The most effective cleaning of high solids RMA has been with a good saponifier (5-7%) [eg, Kyzen Aquanox, Lonox formulations, Envirosense Envirogold, etc ] in deionized water, 150F, with 2-3 DI water rinses. Dull solder connections when you do spot

Now seen the Blow Holes and shallow inverted and non wetting problem an aweful lot over here. Over came the Blow Holes and shallow inverted joints by washing the bare PCB with hot Saponifier then rinse and dry = problem dissapears. Think most PCB ven

Good afternoon everyone, We have a customer that wants to specify "cleaning processes" on a board that typically has a "no clean process". Normally, I would not care, but I have one component on this board for which I question the cleaning process.

Hi Joane, this flux is primarily designed for wave soldering. I think that manual soldering it´s possible. Certainly it´s very hard to dispensing correct amount of the flux. Succinic acid is one from all ingredients of this flux. If you have this

Hegemon, Thank you for the acknowledgment. Jacki, There are 3 rosin flux categories: R – Pure rosin (no cleaning required) RMA – Rosin mildly activated (can be used without cleaning in non critical applications) RA – Rosin highly activated (due t

wlsmt: You’ve got to help us out here: * Why did you apply solder paste to capacitors prior to water washing the PCBA [where the caps were attached?]? * Did you reflow the Alpha WS-609? * How is the Alpha WS-820 involved in this? * Talk about the

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
