IMHO I would avoid sprayed silicones like the plague. They can travel around your facility and cause solder wetting issues that you will never know the root cause for. Also found this e-drive article on using silicones around motors and relays. Loo

I'm not that concerned about the solderability of the motor. Our customer is concerned about the outgassing of the conformal coat effecting the motor brushes. Silicone will break down into SiO2 and SiC will result from a spark between the brushes a

Thanks to all for the info. The ideas to correct the situation are all excellent and if we see any more boards from this source with this condition we will know what to do now. In the end however, the real questions we are trying to answer are, 1.I

We are a pcb manufacturing facility and we have a question. We wash our boards in a metal wire rack that has latex � inch tubing connected to it so the pcbs do not move from water or air flow. It acts as a buffer between the wire cage and the pcb. Ca

Mydata would be good, Contact Systems would be good for what you are doing, very good software, crappy feeders but fine for 0805 parts. You may be able to get a Universal GSM pretty cheap these days. If you make a decision then look for a machine you

Hey Guys, We are looking to set up a line to manufacture low volume high mix PCBs. We have work in the display technology and military sectors. Part tracking, lot tracking are critical. The machine may also end up in a class 10,000 or 1000 clean room
