We have carriers that we use in wave flow solderers that are machined specifically for each board out of ESD composite. I was wondering if anyone knows about lead contamination of this material and the cleaning of composite? I know that it is a p

Does anybody do this? Are there any problems with doing this? Thanks Craig

I suggest not to. You are also adding the flux of the paste that may cause you trouble in the long run. I suggest setting up a reclaim process with you paste vendor, or someone they reccomend.

Hi, I would appreciate some help here.. I am black residue with my wave soldering provess with my Electrovert machine sometimes, they are dotted all over the board ! I am also using no clean flux through an externel spry fluxer unit.. thanks Darren

Daren: suggestion from a friend of mine 1. Is residue on the top or bottom of the board? If on the bottom, then you might need to do solder dedross. if on the top, you might need to check 1. after spray flux, check for any excess flux on the top of

HI all, thanks for the advise.. Electrovert is being used from 7am to 7pm and we do dedross from the surface of the solder bath during lunch time around 12nn. Break Time we just sweep them to the side.. Every two week, we do the solder bath maintena

I ever thot of changing the whole solder pot altogether but then it prove to be a costly measures.. If looking at the source of the problem, it might be mainly due to the way that the machine had been maintain... Anyone care to share how they are per

Robert: Several points: 1 Dross is a mixture of various things with no "fixed" composition: � The obvious things are metal oxides mixed with metal and this can vary in color with temperature and composition - remember some intermetallic oxides form

Even the level of solder in the pot can have effect on your wave height. backflow gate may have been tweaked a bit, that affects wave height, many many things affect the proper RPM required for the correct wave height. Pot may be a little lower tha
