The Retronix IC Recovery process: Why it will change the landscape of the IC recovery market.

The philosophy of the Retronix IC recovery process is built around industry standards, adopted by the largest IC manufacturers. For them, when you are soldering ICs to PCBs, temperature and time are your enemy. The higher the temperature, and the longer the profile, then the more likely damage is to be caused. Think of passing your wet finger through a candle flame, no damage. Then think about holding it there for a minute! IC Manufacturers state (as a rule) no more than 3 or 4 reflow cycles should be carried out on an IC, but up to that number is fine:

Micron - "The maximum number of reflows is defined as three...product guarantees may be invalidated" (Ref 1.)

Xilinx - "Pg.11 JEDEC STD-20 compliant Packages capable of withstanding high reflow temperature rating (245 C-260 C) for 3 reflow cycles" (Ref 2.)

INTEL - "Many BGAs (including Intel BGAs) are rated for 3 reflow cycles" (Ref 3.)

Intel specifies two more points which are relevant, in the above referenced document, point 9.4.4.1 specifies, that the profile goes above 154 deg. after approx 1.9 minutes, and does not come below 154 deg. again till about 6.4 minutes. So it is above that temperature for approx. 4.5 minutes, moreover some profiles are even longer than this.

Keeping the above standards in mind, the Retronix IC Rescue process is different and unique as it manages to stay within all the stated manufacturers specifications, much shorter in terms of temperature and time, safe and well below stated reflow profiles.

Following comparison shows the traditional method  to the Retronix method, and how the Retronix IC recovery method is changing the landscape of the component recovery market.

The first time the component goes onto a PCB it has gone through a reflow profile, therefore the count starts from 1.

As can be seen from the comparison above:

The Retronix IC Rescue method is well within the manufacturers specifications, the process is automated, controlled and completely safe. 

Additional benefits of Retronix IC Rescue method include an automatic wash which makes sure each IC is clean, a mechanical test to verify functionality, including curve trace test, key functional test and memory test. A solderability test and XRF test to verify composition of leg or ball.

Retronix 'IC Rescue' process helps maximise returns for a service repair company.

A service company that specialised in field repairs of telecommunication systems had a large quantity of spare PCBs, all brand new, that they bought in order to carry out repairs on systems. The product turned out to be far more reliable than estimated, and the product did not sell in the volumes expected.

The end result was that the service company ended up with a large quantity of brand new PCBs they had no use for, and there was no obvious external market.

Using Retronix’s “IC Rescue” process, the PCBs were stripped of valuable ICs, which were then offered to the market as 100% genuine, zero hours use ICs which were safely recovered from brand new PCBs.

These were either utilised on other PCBs which used the same chips, or sold on the general market to other companies, who knew they were recovered but also knew it was done with zero reflows and were from brand a new certified product.

This allowed the service company to maximise their return  on this product which otherwise would have returned no value, other than precious metal recovery.

Anti Counterfeit IC Testing : Visual Inspection

As part of the Retronix Anti-Counterfeit IC testing service a customer approached us asking for our level 1 authenticity test, specifically the visual inspection service.

The customer send us approximately 3000 qty - NUD4700 type parts and asked to pick a random sample of 11 for visual inspection to check for authenticity. The reel information and datecodes given were the following: 

    Where :

  

    M = Date Code

    MNH = Device Code

    . = Pb-Free Package

The first check straight away points out certain discrepancies.  Markings do not match the information on the datasheet, and the direction of the text with reference to the Anode was found to be incorrect, further inspection about the device itself revealed the following:

As it can be seen from the datasheet image and from the image that is sourced from Mouser Electronics, the bottom side of the device should be connected to the Cathode and continue onto the entire bottom side. But as can be seen with the image of the device on the right that these devices have two isolated pins with the bottom side being the outer casing and not a contact, this shows us that the device in question is not as per standard and is considered suspect.

Continuing investigation of the device for further inspection shows:

1                                              2        

Device contacts are found to be incorrect, Anode and Cathode are formed into a gull wing as can be seen in 'Image 2' and not as they originally should have been as shown in 'Image 1'

Conclusion :

The visual inspection of the sample puts the batch as suspect and cannot be termed original as per standard datasheet and information available about the device. The report along with all photographic evidence and technical information was provided as a report to the customer as suspect counterfeit. This gives the customer a good insight into future purchases from the buyer and also this current purchase which could have caused big issues in case the customer would have gone on and implemented the same into his supply chain.

The Retronix advantage: Recovering and reusing ICs from scrap or obsolete PCBs

A CEM had a large customer base of complex telecoms PCBs, and found these difficult to debug if they failed after assembly. This was mainly due to their being such a large amount of revisions, the techs found it difficult to be familiar with all of them.

Subsequently there was a lot of PCB “shotgunning” going on. This was the practice of making an educated guess at what IC was causing the issue, and changing it. This meant a huge expense in ICs, most of which were thought to be fine; it would be a solder problem causing the fault (open or short under the BGA).

So they introduced an exercise of sending the removed ICs to Retronix for IC Recovery, and putting them then back into the repair loop. For IC Recovery were also sent 3^rd time failed PCBs.

This resulted in a 61% drop in IC cost in the repair area, with no noticeable difference in test yields.

All the ICs were tested electrically by Retronix before being returned.

Retronix working with Service Repair Companies

A cell phone company manufactured its product in Asia, but had an EU Service based operation for EMEA. The service operation had small easy fix/replacement centres scattered around EMEA, but central repair facilities for PCB debug and repair issues.

It bought parts in bulk from HQ, but experienced many issues with parts shortages, over stocking and obsolete stock at the end of life for a product.

Retronix introduced a programme whereby they recovered the scrap PCBs from the company’s CEM manufacturing operations in Asia, (which were previously landfilled) and recovered the ICs locally. The recovered ICs were then shipped to the EU and held by Retronix free of charge. The service company had online access to all parts held, effectively parts held which had cost nothing, and were known genuine.

The service company would then call off parts as needed by its repair operations. At this point the parts would be refurbished using Retronix’s “IC Rescue” safe process and shipped in a few days to where they were needed. At this point Retronix would invoice for the refurbishment, which was a fraction of the cost of buying new.

The service company experienced no issues with these parts, which were brand new with zero hours use, and had been recovered using the safe “IC Rescue” process.

This successful programme slashed the parts costs of the service company, in terms of both buying and sourcing, as well as reducing obsolete costs massively.

A possible solution to “Hard to find electronic components”, when you cannot find the new parts, on time

A USA based OEM was looking for Xilinx parts but they could not be found within the timescale. It was offered parts by a broker in China which were advertised as “refurbished”. After further investigation, the OEM found out the parts were on scrap PCBs which the broker had bought from a local CEM. However the part were still on the PCBs, and the PCBs were in ESD bags, in boxes.

The broker was planning on outsourcing the recovery and refurbishment of the BGAs to a local company in Shenzhen, however Retronix was asked by the OEM to do the BGA recovery.

IC Recovery/ IC Repair

We recovered the Xilinx parts and others from the PCBs locally in Shenzhen. This was done using our new “IC Rescue” process that recovers ICs without a reflow cycle in order to comply with the IC manufacturers’ specifications.  The parts were packed and shipped to our European facility. Shipping of the ICs only was low cost. The remainders of the PCBs were sent for recycling in Shenzhen.

BGA Reballing

Retronix then removed the excess solder from the BGAs, using a controlled process without reflow or abrasion, then cleaned the parts and immediately reballed them. The parts were mechanically & electrically inspected and packed to be shipped to the USA based OEM.

The parts were placed without any issue and zero failures were reported.

Certificate verification

The remainder of the parts were held by Retronix pending sale by the broker, and were sold with a “Retronix Certified” certificate of conformance, protecting the broker and the end user.

IC Recovery: Retronix “IC Rescue” process in action

With the demise of Nortel, it has left existing users with a problem if they want to expand their existing Nortel telecoms telephone system – where do they get the hardware?

Flextronics were tasked with supplying a daughter board for an exchange, and could source all the parts apart from one – the Nortel processor itself.

The part was a NT6X54AA ASIC, long since out of production. The only alternative at the time was to set up a production run to make a batch of chips – however this was a massive cost.

Then it was discovered that although the revision of daughter board needed did not exist, earlier revisions of the board existed in quite large numbers – and the only constant between all the revisions was the ASIC chip!

So Retronix was asked to carry out a recovery operation on the chips so they could be re-used.

Retronix used their unique IC Rescue process to remove and refurbish the ASIC chips without using any dangerous heat or abrasive processes. All chips were then fully tested, both mechanically and electrically, and supplied to the CEM to be installed on the latest revision of PCB.

This proved a highly successful operation, with no reported field failures after 2 years of installation.

For further info on how Retronix can help you recover chips for reuse, to either save money, the environment or because you cant source them, email us at info@retronix.com

Combating Counterfeit

Evolution of the Counterfeit Trade

It's the three words every purchasing department dreads - "the grey market."

Counterfeit electronic components have been making their way to the UK market for some time now and it is estimated that 95% of these unsafe and unreliable parts are arriving from Asia - a recent study revealed that the counterfeit industry accounts for 8% of China's gross domestic profit. The Chinese counterfeit market is becoming more and more sophisticated and those involved are spending vast amounts of time and money on developing new ways to "fake" components.

Most CEMs, franchised brokers and non-franchised brokers have had some experience of counterfeit components in the past. Using these parts can lead to massive financial liability as well as loss of reputation - it is believed that counterfeiting costs the semiconductor industry around $7.5 billion every year in lost revenue.

Combating Counterfeit Worldwide

There are ways to stop the spread of counterfeit components. 

Retronix has been at the forefront of the "combating counterfeit" initiative for a number of years and has recently invested significantly in state of the art testing equipment to help in the fight to stop counterfeit components reaching production lines all over the globe.

Ensuring Authenticity of Components

For Retronix's strategy to be effective, it is vital for the purchasing professionals, distributors and brokers to become part of the fight and use Retronix's services as the first line of defence. Send your grey market components to Retronix for testing before you purchase them and, provided that they pass our scrupulous testing process, you will be able to hand them over to your customer with our certificate of authenticity.

Retronix has also developed a revolutionary process that allows us to recover components safely from obsolete PCBs without the component die reaching reflow temperatures. Apart from the obvious cost savings, this also ensures that the history of the component is traceable - meaning that you have no doubts about their authenticity.

All components that are recovered using the Retronix method are tested, baked, packaged in tape and reel or waffle trays then vacuum sealed. Working to IDEA-STD-1010-B standard, Retronix offers various tests including:

• Visual Inspection
• Acid Wipe Test (examining component for changes to screen printing)
• Curve Trace Test (powered and un-powered)
• Key Functional Test
• De-capsulation
• Ionic Contamination Test
• Solderability Test
• X-Ray
• XRF    

We know that careful and thorough testing combined with our unique component recovery process will help in the fight against counterfeiting and ensure that you provide your customers with authentic and reliable components. To find out more about what Retronix can offer, please visit our website or email one of our team members.
