Now the ball starts rolling. I'm lookin' for a new aqeous cleaner. Do I really need chemical cleaners or saponifiers, surfactant etc. for an Aqeous Cleaning Machine in removing OA or Water Soluble flux from under my 1.27mm Pitch BGA down to 1mm Pitch

Hey guys - our lab has some data and photographs available for the MS2 for use in wave solder from some of the studies we have performed for P Kay. There are other versions being studied, but that is the only version available to market currently.

I was able to escape from Riyadh last week to attend APEX. PK Metals actually had a booth where they did a live demo. They had a working solder pot with dual wave, and demonstrated how their material acts as a barrier to oxidation, which causes dro

Let me give some information on the use of MS2. The average wave solder machine will use one liter per five day week per 8 hour shift. The usage can vary + or - 20%. Instead of removing 6 to 10 Lbs of dross every 3 hours you will have to remove 100 M

Baer, Sara, et al., Thank you all for your responses. I apologize, we have a new line installed and have been quite busy the last month... I'm downloading the video as I type this from pkay. Samir, please, if you get the sample and give it a tri

We have a great deal of new reliability data and we are preparing a full document that shows the statistically valid reduction in solder related defects as well as the improved throughput. It will include all of the SIR test results which are all goo

A 70 reduction in solder useage is about what we are seeing. You are correct that there are machines that work better with MS2 than others. We are able to make slight modifications to those units, mainly making it more difficult for dross to hide fro

I agree Patrick many people blame the assembly fluxes when it is some other hygroscopic chemistry left on the bare PCB such as surfactents from the HASL process these will do exactly what the guy reported in his post fail then cool down and pass ever

Causes of dewetting in conformal coating. Factors that influence dewetting usually involve non-ionic contamination such as: * Residues from board manufacture including silicone surfactants from solder resist & HASL rinse contamination * Component res

Improper washing of water soluable flux residues can be a major contributor to flux residues remaining on the board surface. ;-O That you appear to be only complaining about the pathetic state of the ability of your washer to clean under BGA, it may
