Hello. We are building a CCA which has a silicone-based adhesive whose purpose is to bond the bottoms of multiple LED displays to heat sinks. Our customer wants the CCA to be tested for ionic residues per J-STD-001, but we are hesitant to test the

Are you performing ionic contamination testing?

Hi -K We are a manufacturer of ionic contamination testers (not yours). In most cases, automatic mode is appropriate. In some instances however, you may need extra time to �release� entrapped contamination from the sample. Automatic mode is not a

Where on the assembly is the dewetting occurring? Factors that influence dewetting usually involve non-ionic contamination such as: * Residues from board manufacture including silicone surfactants from solder resist & HASL rinse contamination * Comp

If no-clean flux is reflowed correctly, many of the activators are encapsulated within the resin residue left behind after reflow. An ionic contamination test cannot differentiate between ionic residue that was encapsulated (not harmful) and residues

We understand that testing for ionic contamination and surface insulation resistance measure different properties. We assemble printed circuit boards for other companies. We will not get combs on 90% of the boards that we assemble. We have no custo

From personal experience, if the PWB vendor is cutting costs and doing their final rinse with tap water instead of DI you will get ionic contaminants left on the board. You might consider having CSL, or one of the other independent labs mentioned e
