Is anyone aware of any white papers regarding the possibility of lead contamination on ROHS assemblies from using the same test fixture with the same test probes on both tin/lead and ROHS assemblies. We have customers switching over but we are still

since IPC-J-STD-001 RevH obsoleted the 1.56ug/cm2 UCL of ionic contamination tester in testing using ROSE test, how do you define the acceptable limit per PCB assembly? thanks

The industry standard for Resistivity of Solvent Extract (ROSE) Testing analysis is IPC-TM-650 Method 2.3.25 – Detection and Measurement of Ionizable Surface Contaminants by Resistivity of Solvent Extract (ROSE).

We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

Hello, tried searching the SMTnet archives, but not yet a clear answer - maybe there is not a one yet ? ;) last discussion I found is few years old so maybe there is a fresh view on that? Q: we want to prove that our proces is "clean" we use SAC30

I'm looking for test labs in Taiwan that are capable of performing ionic contamination testing on small to medium sized SMT boards. I'm interested in both ion chromatography and ROSE test methodologies. Is anyone aware of any labs performing contami

How does no-clean flux residues on a PCB assembly impact the ROSE testing? Does no-clean flux residues on the PCBA dissolve in solution of ROSE tester and increase ionic contaminants level in terms of NaCl per surface area? Is ROSE tester solution (a

Casimir: Let me expand on something that I said in my response to your thread on ionic testing. Generally, no-clean people don�t use ROSE testing as part of their process control, because the ROSE test is essentially washing your board in DI/IPA �

We use a NC Flux in the wave solder and after aAcelerated Life Test cicle we found contamination white residues paths between some solder points. Does somebody know a possible cause for this contamination.

Do I need to have an Ionic Contamination tester if my process is no-clean?
