I know - A stimulating topic.... IPC-TM-650 2.3.28 method calls for a PCBA or PCB to be placed into a bag with solution, shake, analyze. Great. There is a method of doing this testing that focuses on a specific area of a PCB or a component where r

Hi, Thank you for your answers. But I want to explain some points on which I would appreciate any comment: * Having calibrated the process, we intend to carry out the ROSE test just on SAMPLES of the finished boards. Lets say one every hour. I exp

Both are equally efficient process control tools. Neither is particularly effective in testing ionic contamination. The best way to sell your customer on allowing you to do this is to show them that you understand the WHOLE process and are able

Graham: I agree. Very thorny. What is clean?? And how is that controlled?? Back 25 or so years ago, soldering was done with high solids rosin fluxes. The issue with cleanliness was ionic contamination. The US military and others set a fairly a

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
