Defence, Medical & Aerospace PCBs

Retronix’s innovation provides authentic, safe & tested components

“Innovation distinguishes between a leader and a follower.” Steve Jobs

Using our unique processes such as our latest automated Alloy Conversion/Retinning; ICs can be recovered and reused from obsolete PCBs or manufacturing fallout, even applicable to Military Electronic Components.

This means that the AUTHENTICITY of the components is established which eliminates counterfeit components and stops them being introduced to your supply chain.

Our unique processes use NO REFLOW CYCLES or abrasive techniques to do this, ensuring the most reliable product

Working to IDEA-STD-1010-B standard, Retronix can test your components to ensure authenticity and thus limit the chance of a counterfeit component entering your supply chain.

Defence/Medical/Aerospace are vulnerable to counterfeit ICs

Many defence, medical and aerospace systems rely on electronic parts that are no longer produced by the original manufacturer or sold by their authorized distributors. That reliance is based, in part, on the long life cycles of these systems.

An electronic part may be manufactured for two years, but many defence, medical and aerospace systems which use these parts may be in service for more than two decades. Older components often need electronic component test & retinning to avoid solderability issues like tin whisker.

These high reliability industries are critically dependant on a technology that obsoletes itself every few years (or faster), is made in unsecure locations and over which it has no market share influence.

To source scarce parts, purchasers in the defence, medical and aerospace industries often buy from independent distributors or brokers. This introduces a high risk of faulty or counterfeit components being acquired.

Retronix’s testing laboratory detects counterfeit and faulty parts and prevents them from being acquired. When we recycle the components from authentic PCBs, safe, reliable and tested ICs can be sourced instead of taking the risk associated with non-franchised brokers. Any ICs we source will have been processed properly, have no tin whisker issues and be functional.


Automatic re-tinning and alloy conversion of leaded devices

“It is the quality of our work which will please God and not the quantity.” Mahatma Gandhi

Retronix have made a substantial investment in a fully automated re-tinning and alloy conversion machine to ensure that we provide the best and most reliable service for our partners.

The system is an LTS-QFP system modified to comply with our detailed specifications and provides automated tinning process in accordance with ANSI/GEIA-STD-0006-2008 standards.

This is a complete system providing “hands off” solder dip coating of fine pitch QFPs, other SMT devices and all PTH devices. The machine will leave components with a SnPb finish thus avoiding any possibility of tin whiskering.

We are constantly improving our services to make them safer, more reliable and more repeatable.

Alloy conversion of BGAs and micro BGAs

Retronix have developed a process that can safely remove existing solder spheres without any abrasive contact or reflow cycles then place new solder spheres using a laser process – again with no reflow cycle.

This process can convert any device from lead-free to leaded, or vice versa.

The process DOES NOT subject the silicon to the reflow temperatures associated with mass reflow.

All components that pass through Retronix are 100% AOI inspected and you only pay for the components that PASS this inspection criteria.

We do work for many defence companies who perform audits on a regular basis and we comply with the necessary quality standards to ensure that this service is safe, reliable and of the highest standard with class comparable to the best of military electronic components.
