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

It is still a big concern on using No-clean or aqueous cleaning for CSP assembly. I prefer to use no-clean, however, not all components are suitable to use it. Especially those dirty capacitors or connectors which may cause solderability problem. It

I'm afraid we don't agree regarding the best test method to use here. My understanding is as follows. The omegameter test measures board-level, ionic contamination (i.e., average for the entire board area and all components); it does not tell you w

Dear Micheal, SIR test is used to characterize fluxes by determining the degration of electrical insulation resistance of rigid printed wiring board specimens after exposure to the specified flux. (IPC TM-650 #2.6.3.3 http://www.ipc.org/html/tm2.6.h

Kelvin, Yes, we're referencing the same spec. I performed the test under the Class 2 conditions (except that I used a 100V bias rather than 50V...but my water-washed microBGAs still passed). Regarding the omegameter test: we have this instrument,
