Dear colleagues,
We would like to rationalise our PBA materials (solder pastes, flux)
qualification procedures. Our question is:
What is the added value of tests/measurements like halide content
determination,
copper mirror test, electromigration, silver chromate paper test, etc.,
when one does a Surface Insulation Resistance (SIR) test? What do they
tell more about the final product reliability? Does the SIR test not
cover it all? For example, should we be worried about the halide
content when the material passes the SIR test?
We welcome any comment.
