Dear Mr. Stephen: After all boards we lost & hard time we had, the only convencing solution for us is to run a good pc_motherboard (which is our product)to confirm the experiment. After that we need to remove the big BGA ,clean & flux the PCB then s

Steven, While agreeing with your method here, I also would like to ask a question since we're right on that subject. Have you ever experienced problems with IR heating while working with a Heat-Slug BGA, or a Viper BGA where the whole top is covere

Roland: Speaking of the archives, what are your plans to make the archives earlier than the first part of 2000 available to SMTnetters?

Humm OK - sort of what i thought - So 90% of the time it's something else - but I assume that if you say that you are fairly confindent that you have a robus process around BGAs - where as i do not. Can we assume that it is actually the BGAs (as so

Sorry for the late reply, I am an ersa dealer may I suggest mounting an alternative thermocouple attached to a DMM in close proximity to the BGA. See what the differences are in your readings from the DMM and the Digital temp reading on the IR550A. I

Thanks, We currently use Metcals for our regular work and I was looking at the ERSA system for the BGA rework. From what I have seen it seems simple to use, and since it uses IR you don�t need all the attachments for different size BGA�s. You just

I use the exact same paste flux that we use in our solder paste for SMT manufacturing with great success. I have also had great success using the Air Vac DRS Hot Gas units with the same size BGA's. If to much heat is applied to fast to the BGA be it
