First, you must determine a few things: 1. What specific de-fluxing chemical are you going to use? Basic required determinations include the chemical�s pH, is it a VOC (if so, what is its VOC content), what concentration is the chemical used in (1

Thanks Davef, unfotunately in order to keep TIC of PBA inside our customer TIC requirements, we have to pre-wash (DI water only)connectors before assembly. Too high level of Br- continuosly get released by connectors molding compound. Our assemb

What does your flux supplier say?

Hello, The first thing that you need to do is to make process mapping about this incident, so you can exactly determine all factors and observable changes happened during 2 weeks of timeline difference. According to my experience, if all equipment

This is one of the most common questions I get asked. Why clean no-clean flux. It was stated earlier that no-clean residues are benign. This may or may not be accurate. It depends on several factors including the reflow process. In a perfect world, t

Cory, I've got a lot of experience of testing of this type. The physical (not chemical) nature of the flux residues is the crucial issue in compatibility. If you have a softer residue (either caused by a thick initial solder paste deposit, or a low p

Dear All, I would like to take your opinion about the result that we have faced after cleaning the PC assemblies in a cleaning machine (Miele Dishwasher) with the cleaning detergent Qualitek Everkleen 1005. We use DI water for cleaning purpose in t

Hey Dreamy, Dave is correct. If you attempt to clean your water soluble (OA) flux with water only, you will turn the no-clean flux white. No inspector or end-user will accept this. If a proper cleaning system is not available to you, then I would

We too use both Water soluble and No-clean in our shop. I can tell you that we have won 6 different contracts from other local contract house because our boards "look pretty". It's amazing how some customers judge how other houses build their board
