Retronix Component Recovery: Pioneering Sustainability Through Circular Economy Solutions

Retronix Component Recovery SERVICE: ADVANCING Sustainability Through Circular Economy Solutions

The demand for electronic goods is skyrocketing. However, this rapid growth in electronics consumption has led to a concerning rise in electronics waste (e-waste). The necessity for effective methods to recover and recycle these discarded materials is crucial. One such pioneering solution comes from Retronix Component Recovery Service, a service dedicated to promoting sustainability through circular economy solutions.

The Growing Dilemma of E-Waste

PCB in landfill

The swift pace of innovation, combined with the short lifespan of electronic products has resulted in a substantial increase in e-waste. 

According to the Global E-waste Monitor 2020, the world produced a staggering 53.6 million metric tonnes of electronic waste, and only 17.4% of it was properly documented and recycled. The remaining waste often ends up in landfills or is incinerated, leading to pollution and the squandering of valuable resources.

Embracing The Concept Of Circular Economy

The concept of circular economy has gained considerable importance in recent years. This approach promotes sustainable production, reuse, and recycling of materials throughout their lifecycle. 

By applying circular economy principles to electronics, it’s possible to minimize waste and recover valuable electronic components that can be used again in new products. This creates a closed loop system where waste is minimised, and everything services a second purpose elsewhere in the supply chain.

INDUSTRY APPLICATIONS

Defence, aerospace, and military sectors are critical to national security. The systems they operate are time-tested and have long lifespans. However, the electronic systems that run on these platforms are often obsolete or no longer produced.

Retronix’s component recovery service offers the best solution to obtain electronic components from their own old and scrapped boards for reuse. This not only ensures the availability of tested and qualified components, but it also prevents valuable critical components from being sent to landfill. It also prevents components being sourced from unknown or geo-political sensitive areas, thus mitigating the risk of counterfeit or malicious components entering the supply chains.

Ensuring Military-Grade Durability : The importance of Component Recovery, Laser Reballing and Automated Retinning in High Reliability Electronics

Ensuring Military-Grade Durability : The Importance of Component Recovery, Laser Reballing & Automated Retinning in High Reliability Electronics

In high reliability sectors such as aerospace, defense, security, and space, failure is not an option.

These sectors demand components that can withstand extreme temperatures, vibrations, and radiation among other external stresses. Component preparation solutions like chip recovery & reuse, laser reballing, retinning can help extend the life of these critical components.

Chip recovery involves removing and testing for root cause of failure, the information can then be used to improve the design and quality of future components. It can also lead to cost savings by identifying components that can be repaired rather than replaced new, this safeguards the supply chain against counterfeits, and reduces long lead times on critical components. 

Laser reballing and Automated retinning involves applying a new layer of solder (Pb or Pb Free) to legs of the device or spheres in case of a BGA, this can help in increasing the reliability of the component by reducing the risk of solder joint failures and mitigating tin whiskers.

Overall, the automated high reliability component services can help ensure the safety and reliability of personnel and equipment, while also reducing costs and improving performance.

The Importance Of Military-Grade Durability In Electronics

The need for military-grade durability in electronics is paramount, especially in sectors such as aerospace, defense, security and space. Electronic components in these sectors must endure harsh environments, including extreme temperatures, vibration and shock.

They must also operate reliably and safely in critical applications; where failure can lead to catastrophic consequences. Therefore, it’s essential to ensure that electronic components are not only repaired but also restored to military-grade durability.

The requirements for military-grade durability vary depending on the sector and the applications. For example, aerospace and defense sectors may require chips to meet the MIL-STD-883 or MIL-PRF-38534 standards.

Component Recovery & REUSE

Component recovery is the process of removing electronic components from a circuit board or other electronic devices for reuse or recycling purposes. The process involves the use of specialized equipment and techniques to remove components safely and effectively without damaging them, i.e using minimal thermal stress.

The benefits of component recovery are many. It allows for the reuse of expensive chips and reducing cost of repairs. It also reduces the lead time for replacement components and safeguards supply chains against counterfeits. Additionally, it reduces e-waste which is beneficial to the environment. 

Component reclaim is a critical process and it is essential that it is done exactly in conformance with the high reliability standards to avoid damage to the chip set.

Laser Reballing

Laser reballing is a process of restoring the solder balls on a component to their original condition or the desired solder alloy. This process is necessary when the solder balls on a component have been damaged, removed, or if the solder alloy needs changed. Laser Reballing involves the use of a laser to attach new solder balls to the component.

The benefits of laser reballing are that it allows for the reuse of expensive BGA’s reducing the cost of repairs. It also reduces the lead time for replacement components. Retronix carry out laser reballing to the IEC Standard.

It ensures that the chips are restored to their original condition without using a reflow/thermal cycle – therefore it meets the required standards for military-grade durability.

Automated Retinning (ROBOTIC HOT SOLDER DIP)

Retronix Automated Tinning Process is a state-of-the-art technology that offers an innovative approach to automated tinning, making the process faster, more efficient, and cost-effective. 

Robotic hot solder dip technology is a process that involves dipping the component leads in a batch of the desired solder – the process is controlled by a robotic arm, which precisely dips the leads for a predetermined amount of time. The solder creates a strong and reliable bond between the leads and the circuit board.

This automated tinning process offers advantages such as consistency, precision, and improved quality control, making it an ideal solution for various industries, such as aerospace, defense, security & space.

As the world continues to become more environmentally conscious, many companies and industries are looking for ways to reduce their carbon footprint and become more sustainable. One of the most effective ways to do this is by transitioning to a circular economy. This blog article will look at how the circular economy can be accelerated in automotive electronics, data centres, and Electronics manufacturing.

Retronix Component recovery, re-use & circular economy solutions

What is a Circular Economy?

A circular economy is an economic system that is based on the principles of sustainability. It works to eliminate waste and pollution by focusing on reusing and recycling materials. 

In a circular economy, goods are designed to be reused, repaired or recycled. This reduces the amount of waste that is produced and helps to conserve natural resources. 

The benefits of transitioning to a circular economy are numerous.

For one, it can help reduce the costs associated with waste disposal and resource extraction.

Additionally, a circular economy can help create jobs and stimulate the local economy. Finally, it can help reduce carbon emissions and promote a more sustainable way of doing business.

AUTOMOTIVE ELECTRONICS AND THE CIRCULAR ECONOMY

Automotive Chip Shortage

Automotive electronics are a critical part of the automotive industry. They are used to control the functions of a vehicle and enhance its safety and performance.

In a circular economy, automotive electronics can be reused, repaired or recycled. 

Reusing and recycling automotive electronics can help reduce the costs associated with manufacturing/sourcing new parts and it also helps with safeguarding the supply chains by not having to source them from unknown suppliers.

In order to facilitate the reuse and recycling of automotive electronics, companies need to adopt innovative technologies and processes. This could include Retronix component recovery solutions that help with re-introducing safe components back into the manufacturing process.

Additionally, companies could also partner up with companies that provide automated testing systems to ensure that recycled parts meet the highest standards of quality.

DATA CENTRES AND THE CIRCULAR ECONOMY

Data centres are an important part of today’s digital economy. They are responsible for storing and processing large amounts of data.

New initiatives seek to combine data centre management with the core principles of the circular economy, such as disassembly and reuse.

By doing so, data centre operators can dramatically reduce their environmental footprint and carbon emissions, while also increasing operational efficiency.

Component recovery involves the reuse of components from decommissioned or retired servers and other hardware, as well as the responsible recycling of non-reusable parts.

This approach can help to reduce the total carbon footprint of data centres, as well as the overall cost of operations. It can help to reduce the amount of e-waste associated with data centre operations.

THE BENEFITS OF COMPONENT RECOVERY, REBALLING, RETINNING & TEST

Electronic component reballing, retinning, and recovery can bring many benefits in a circular economy. Reballing and retinning can help extend the lifespan of existing components, while component recovery can help minimize waste and reduce the need for new components.

Reballing is the process of replacing the solder balls on a component. The solder balls are melted and then replaced with new ones. This helps to extend the life of the component and reduce the need for new components. Retinning is the process of applying a fresh layer of solder to a component. This helps to improve the electrical connection between the components. Electronic component testing is an important process that can help to ensure the quality of components. This could include testing for moisture and temperature, as well as verifying the functionality of the components.

These practices can help to reduce the environmental impact of manufacturing and disposal, as well as help companies save money by salvaging usable components.

It can help to support the circular economy by maintaining the flow of resources, making products more sustainable and cost-effective for the long-term.

Circular Economy- reclaim & reuse electronic components.

Circular Economy - reclaim & reuse of electronic components

The global demand for electronics continues to grow. 

The International Data Corporation forecasts that the internet of things, artificial intelligence, and virtual reality will drive worldwide spending on information technology to more than $1 trillion. In the digital age, electronic products are an indispensable part of our lives. 

However, the fast pace of innovation and short product life cycles also mean that electronics often have a short user lifespan. This has led to a rise in e-waste as well as a loss of valuable resources locked inside these devices. Every year millions of tons of electronic devices end up in landfills instead of being recycled. 

Reducing this waste and finding new ways to reuse or recycle old electronics could help reduce their environmental impact while also driving business value at the same time.

Industrial digitalisation and the circular economy are two important megatrends that can help drive innovation in the electronics value chain. The global market for electronic devices is estimated to be worth more than $177 billion in 2019.  

As a result, companies operating in this sector now need to adopt new strategies to remain competitive in the digital age. One of those is adopting a circular economy approach, which involves principles such as sustainable production, reuse, and recycling of materials at every stage of their lifecycle.

By applying these principles to electronics, computers, server boards, hardware, internet of things, telecom electronics, and more, it’s possible to reduce not only waste but also recover valuable electronic components/devices that can be used over again in new products – creating a closed loop system where nothing is wasted and everything has a second life somewhere else in the supply chain.

Circular economy thinking is everywhere these days. Innovation leaders in every industry embrace circular principles to reduce waste, cut costs and boost productivity.

Cheap as Chips | A Road to Recovery for Automotive

Cheap as Chips | A Road to Recovery for Automotive

The chip shortage is back for Year 2 and, the automotive industry continues to bear the brunt as semiconductor manufacturers continue to neglect their cheap chips. 

Nvidia Corp recently led a string of predictions from fellow chipmakers at the J.P. Morgan Tech Forum with its forecast for the chip shortage. With a consensus that there will be minimal improvement to the situation before the middle of 2022, maybe not even then.    

A somewhat alarming outlook for a sourcing issue that dates back to March 2020 but, of the endless problems thrown at companies by Covid-19, the global chip shortage appears to have been one of the most destructive. Companies should count themselves lucky to have avoided the disruption inflicted by the lack of chips which has caused backlogs for products, including vehicles, consumer electronics, and household appliances.

Legacy Semiconductors

Perhaps no other industry has been as affected by the semiconductor deficit as automotive, with carmakers large and small relying on these tiny computer chips to power everything from infotainment systems to steering wheels and much more. According to US-based consulting firm AlixPartners, shortages related to semiconductors cost the automotive industry a whopping $210 billion in revenue in 2021.

The automotive OEMs aren’t holding their breath about the situation letting up anytime soon, either. As reported by Reuters, Ford has taken the tough decision to suspend production at eight factories following a slump in share. Even Elon Musk has announced that because of the chip shortage, there will be no new Tesla models released in 2022. 

As with most things in the convoluted automotive industry, there are countless reasons why the chip shortage has been so severe. What might be surprising is a route cause to the situation is the type of chips used. Yes, while automotive technological advancements have progressed significantly over the years, cars use a lot of older, lower-tech legacy chips, which cost mere dollars to produce. 

Therefore, mature vehicle chips, which can date back to 2005, deliver a lower profit margin, and ultimately there is less incentive for chip manufacturers to invest in more capacity. Both Infineon and Apple Inc’s Tim Cook have agreed that the market for mature chips would remain tight as semiconductor makers have an incentive to focus on the newest and most expensive chips (Reuters). 

If the semiconductor giants have their way, the days of the automotive industry relying on these cheap commodity chips are numbered. In the meantime, before more factories close their doors, there need to be shorter-term solutions to this relentless chip shortage.  

Component Recovery

While currently there is a lack of capacity for legacy semiconductors, it doesn’t mean that there are no chips out there. However, these mature components might be attached to obsolete PCBs, gathering dust in storage. Retronix has a component recovery service that provides a means to safely remove chips from PCBs and return to a like-new condition. We combine our rework, re-tinningre-balling, ICOS coplanarity testing, electrical testing, and re-packaging services, to ready components for your new builds. 

What’s more, with legacy components dating back to as early as 2005, six years before the RoHS directive, there may be a requirement to convert parts from Pb to Pb Free. Our fully automated alloy conversion system will ensure that your devices aren’t exposed to excessive heat or abrasion, meeting the stringent High Reliability standards of GEIA-STD-0006. Retronix is one of the few companies that offer a full bill of material (BOM) conversion process.

Could chip shortage push automotive towards a more sustainable future?

Could Chip Shortage Push Automotive Towards a More Sustainable Future?

Despite automotive only representing 10% of semiconductor demand, it has been hit the hardest by the global chip shortage. With the crisis showing no signs of letting up, could a Semiconductor Circular Economy put the brakes on the supply chain crisis?

The Impact of the Shortage on Automotive

The global semiconductor shortage has caused carnage across the automotive supply chain, so much so that the everyday consumer has now become affected. Consulting Firm AlixPartners has estimated that the supply chain crisis has cost the industry a staggering $210 billion in revenue in 2021 alone. Shocking but not entirely surprising if you look at the growing list of OEMs that have had to either halt production or shut factories completely, including Daimler, Toyota, Ford, JLR, and most recently Opel.

As would be expected, there are continuing disputes over how long the shortage will last. The year 2022 is being cited by many industry professionals as the holy grail. However, such predictions indicate that there is going to be a definitive end to the draught. The truth is that there has been an imbalance in the semiconductor supply chain for many years now, far before the recent geopolitical shifts, natural disasters, and pandemics (of course). And with the car industry now rapidly pivoting to electric vehicles, attaining a semiconductor supply chain equilibrium seems almost impossible.

A Semiconductor Circular Economy

This dire supply chain scenario has finally forced organisations to take notice of innovations that support a semiconductor circular economy in order to address the current global supply chain imbalance while mitigating future shortages (AZO). More importantly, the model would push us toward a more sustainable future within both automotive and the wider electronic industry.

While electronic goods have revolutionised our daily lives, in this tech-hungry world, we are eating through electronic devices at an alarming rate. Each year a staggering 50 million tonnes of e-waste is produced and, if current trends continue, it is forecast to reach 120 tonnes by 2050. Sadly only 20% is recycled.

Sundar Kamak, Head of Manufacturing Solutions of Ivalua Inc. discussed with Forbes the need for manufacturers to turn their attention to reusing and recycling chips from older devices and equipment, “Not only could this help ease the burden on supply chains, but it will also have a positive impact on the economy and encourage regenerative design to reduce reliance on finite resources”.

How can we Move from Linear to Circular?

For decades the semiconductor industry has relied upon a linear economy model, and therefore, the move to circular won’t exactly be ‘straight’ forward for organisations. However, as highlighted by the UN, moving to a circular approach will open doors to new markets for businesses and provide opportunities to increase market share, cut costs and risks, push innovation and align performance with public expectations.

“Successful businesses of the future will be ones that deliver excellent value with minimum resource use and environmental impacts while moving rapidly toward nature-positive solutions and net zero carbon emissions” UN.

For three decades now, Retronix have been helping businesses adopt the Circular Economy ethos of refurbish and re-use. As previously highlighted by Kamak, everyday, millions of dollars of brand new and high-value components are scrapped by manufacturers simply because they are attached to faulty/obsolete PCBs.

Retronix have developed a process to recover and refurbish these electronic components including BGA chips, to enable reuse. This process meets the component manufacturer’s specifications of maximum reflow cycles allowed on an electronic component, adhered to extensively by both OEMs and CEMs. 

In 2020 Retronix recovered nearly 3 million components from approximately 650,000 PCBs that would otherwise have gone to scrap or landfill. We expect this number to be double this year as due to the component shortage, more and more organisations discovered Component Reclaim as a viable and valuable solution to their component souring issues.

Gray Market – Don’t get burnt by Counterfeit Chips

The Gray Market - Don't get Burnt by Counterfeit Chips

With the electronic component shortage predicted to last until at least 2022, Retronix has not only seen a significant growth of customer requirements for our testing services. But alarmingly, the quantity of counterfeit chips and suspicious components that we are detecting has risen significantly also. During any time of shortage, we observe a spike however, the severity of this particular supply crisis has dramatically worsened the counterfeit chip problem. 

Playing with fire

The top manufacturers within the computing industry are lucky enough to receive orders directly from the chip manufacturers. However, manufacturers from other industries such as automotive, white goods, and medical electronics, source their chip stock from intermediary suppliers. Now because it is near enough impossible for these suppliers to obtain chips directly from the source, many have been exploring alternative channels. As a direct result, the gray market for semiconductors has grown, at an exponential rate.

“The gray market refers to the sale of products via distribution channels that are unintended, unofficial and unauthorised by the real vendor of the products.” Techopedia 

Dubious sellers are taking advantage of the dire situation, luring in desperate buyers with the likes of search engine ads and swindling them fake chips under the guise of genuine stock. 

The Danger of Counterfeit

According to Semiengineering, the counterfeit chip market is growing with a worldwide value of $75 billion. Hand in hand with the industry becoming more lucrative, counterfeiters are becoming more sophisticated in their techniques. However, the difference between genuine semiconductors and fakes semiconductors couldn’t be more extreme. As explained by the Semiconductor Industry Association, chip manufacturers spend billions of dollars each year developing, manufacturing, and testing products that will perform to the highest standards and reliability levels for many years.

Counterfeiters, on the other hand, will repurpose components from old electronic waste using crude and poorly controlled processes that churn out semiconductors with far higher failure rates. This inherently effects the long-term reliability of these devices and worryingly jeopardises lives since they are prone to fail at the worst possible moments, such as when car airbags need to deploy, defibrillators are used to apply shocks, or when aircraft are landing.

XIlINX Device our Test Department Detected as Compromised

Don't get duped by counterfeiters

Retronix has a test department dedicated to the identification of counterfeit parts along with the best tools for this process. We also have years of experience earned from dealing with this issue for numerous customer in varying industry sectors. 

Due to the supply chain shortage, our test department has been uncovering new and inventive techniques that we have never seen. For example, we are starting to see chips with 2D Barcodes that have been laser-etched off. Suppliers will say that the 2D Barcode was only removed to conceal how the parts made it into the open market, encouraging desperate buyers to use the parts, assuring them the functionality of the devices will not be compromised. Don’t fall for it! Any device which has been visibly altered or changed should be considered compromised or counterfeit. This issue has also recently been raised by ERAI and more information can be found on a discussion on the ERAI: Counterfeit Part Avoidance, Detection, Disposition and Reporting Linkedin page.

If you have acquired components from an unverified source or are unsure about the authenticity of the parts, please get in touch with Retronix today.

Tin Whisker Trials & Tribulations | Finally a Micro Component Tinning Solution

Tin Whisker Trials & Tribulations - A Solution to Micro Component Tinning

It’s a well-known fact (there are hundreds of technical papers confirming) that Tin Whisker filaments can grow uncontrollably from tin plating. The danger comes when one of these filaments peels off the tin and connects with an adjacent component causing a short.

When the EU Restriction on Hazardous Substances (RoHS) directive came into place, the High Reliability industry braced itself for an influx of tin whisker issues. That was back in 2011 and thankfully since several techniques and applications to tame the tin needles have been identified.

The Solder Dip Solution

The most common method to eliminate tin whiskers is to convert the plating from ‘lead-free’ (tin plating) to tin/lead plating. The process is carried out by simply dipping a component’s terminations into tin-lead solder. High Reliability industries (aerospace/defence/medical) are allowed dispensation to use tin/lead solder, as they cannot run the risk of tin whiskers long term. Unlike, commercial products such as phones/laptops that have a much shorter life cycle.

However, it’s still not that simple as the conversion process needs to conform to a standard called GEIA which strictly controls dip time and temperature, plus it must be automated. 

The problem is that 0402, 0603, and SOT chip capacitors cannot (until now) be handled in a manner that allows for automation. Such micro components are processed manually by someone picking them up with tweezers and hand dipping in a solder pot. It’s important to note that the success of solder dipping as a solution to protect against tin-whiskers directly depends on coating the exposed tin-plated surface (Electronic Design)

The Cut Corner Solution

Despite this knowledge, many manufacturers are rejecting hand dipping, instead believing that assembling PCBs with lead paste will resolve this issue. The consequence of this workaround is that the lead solder from the paste only covers the sides of the termination but does not reach the top surface. As widely reported by NASA, this process DOES NOT protect against the risk of Tin Whiskers. 

Despite such clear evidence, the general thought process around the tinning of micro components such as capacitors and resistors is, “there is no suitable process that meets the GEIA standard, therefore it’s not a problem” so, issue a concession to bypass it. Or do the above which is a partial solution but not good enough.

The Retronix Solution

With the automated process designed exclusively by Retronix – Patent Pending – to tin micro devices such as 0402, 0603, SOT’s to GEIA standards, the industry finally has a comprehensive all-inclusive solution for tinning requirements.

  • The automated micro tinning process is carried out on our plating systems.
  • The lead-free capacitors are picked up by a specially designed tool that can hold multiple devices at a time.

The devices are moved to the fluxing station & then accurately over the solder wave. The pre-programmed automated system ensures the dip is precise & consistent.
