Hi Ramon, We have had this problem before on our Seho Wave Solder Machine. We are currently using a spray fluxer as well. By imersing the PCB into the flux you stated you are getting good results. What you need to do is check your spray patter

How to clean a contaminated board would depend on what it�s contaminated by, alcohol may be just the thing. If there is bare copper that has corroded that could be more of a problem, or maybe not if its due to poor tinning by the board house you coul

If you go even further, the flux residue actually isolates the joints from the surrounding atmosphere, so it is actually supposed to be there. Adding a step in your process that is obsolete, doesn't comply very good with the whole lean concept. I don

Not to be repetitious, I just don't remember if this has been said or not, I'm old, give me a break. Some people have found that DI water is too thick to properly remove flux residue under low stand-off components.

I believe the correct statement (I've been told) is "the process is no clean". The solder paste is "low residue". As a CM, in the past we had customers that insisted on a wash after soldering. We used DI water with a saponifier which had mixed result

| Hi, | I have a customer who's electronic assemblies produce RF. He is insisting upon aqueuos cleaning. We switched to a no clean solder years ago and no longer have an aqueous system. | Is aqueous cleaning necessary to eliminate 'cross talk' of

We are currently using non clean paste and non clean flux in our manufacturing process. But recently our customer feedback that using a non clean process might cause flux blockage in via hole area and potentially might burn or explode the boards over

We use Kester 979 no clean flux in our Ersa.
