They work great as long as your conveyor speed has been calibrated and checked on some type of PM schedule. On some oven types these sensors can warn you to possible problems with the conveyor speed. Say the oven is calculating that the board is movi

We have been getting solder balls on some of our SMT boards that are scattered across the board. We are using AIMS RMA291 in a cartridge. The profile we run matches what is called out on the tech data sheet for the solder with only the soak time mayb

I'd tend to agree with what the others have said. Check the basics, board supports, setup, wiper paper working correctly. If it's a humidity issue, try taking some paste, place it on a chem wipe, and roll it around a bit, which removes some of the mo

I agree with you 100% Very well stated. No the service guys probably aren't rewarded like they should be. None the less when we become big boys and girls we need to learn when not to have inflamed lower lipps. Believe me, by the time I get to the po

Currently in our facility we store used and discarded flux residues from the wave solder machines in 50 gallon drums. These drums are picked up and disposed of by an outside contractor. During a recent audit we were cited for not having the drums pr

If people use an inert gas, they use nitrogen for mass soldering. Inert gases get progressively more expensive as you move down the periodic table. Many times no-clean flux is less active than other flux types. So, people use an inert gas to lower

I don�t know much about zinc either. I can tell you that zinc forms no intermetallics with lead. So, I�m not so sure that �diffusion� is the correct term. Of the following: * Hwang "Modern Solder Technology For � * Wassink "Soldering In Electronic

FMEA, when used correctly, is an excellent tool. The best thing about it is that it holds INDIVIDUALS accountable. The meeting cannot be closed until specific people (usually process types like me!) are assigned specific duties. I agree with Dave tha

Hello ! That was an one of our troubles. But we decidet it. Our way : 1. Vibrofeeders of Phillips may be ajusted for special ironrails , horisontallylairs , so IC goes permanently and correctly, also we create some acceptable subfeeder for Phillips
