Gen3, a British manufacturer of testing and measuring the electronics industry, announced that Dr. Chris Hunt, Technical Director, will present at the SMTA Electronics in Hard Environments conference. The presentation “Objective Evidence and How to Convince Auditors” will be held on Wednesday, May 18, 2022, from 16:30 to 17:00 at Park Plaza Victoria Amsterdam.

Gen3’s Dr. Chris Hunt will address the issue that everyone faces in the global industry, what does “Objective proof” mean / require?

  • This will be a measurement system that will be repeatable and reproducible and that may have an indicator that is directly related to productivity.
  • It is an appropriate indicator for the ECM resistance.
  • ECM manufactures corrosion products and ion currents that contribute to unwanted circuit elements.
  • Therefore, the measurement of the insulation resistance between the characteristics of the circuit provides a direct indicator of the efficiency of the circuit.
  • SIR and CAF are examples of techniques that measure resistance and therefore provide objective evidence.

SIR, for testing validation processes, was first created more than 30 years ago. It was a separate product from the British CFC Elimination Project, led by Dr Colin Lea OBE, at the British National Physics Laboratory. With the then entry of fluxes without cleaning, this was the only test method to determine the electrochemical reliability and therefore acceptable purity used at the time.

It was found to be unsuitable for process control and that ion process contamination testing (PICT) should be maintained for rapid and effective control within 15 minutes.

In the last 2 years IEC has introduced new test methods:

  • IEC 61189-5-502 – Surface Insulation Resistance (SIR) Testing of Assemblies – 2021
  • IEC 61189-5-504 – Ionic Contamination Test (PICT) – 2020

Gen3’s presentation will look at other test methods and compare their pros and cons, including ion chromatography, FTIR, SEM + EDAX and new digital microscopy.
