| I am in the process of documenting the SMT process for the PCB Dept. I wonder if there may be something out there already formatted, I want to do an overall procedure instead of individual ones for now. Pat: We write our work instructions for in

| We want to produce BGA�s which will be see burn in conditions | of 140�C / 24h active tested. | Now we think about problems for the solderball uniformity. | Does anybody know about problems or about special solderball | alloys for such productscon

I realize this is a SMT forum, but I have another problem related to electronics assembly and hope there will be someone out there that can save my life (this time). We build quite a few VME assemblies to which we attach a SAM board. Fairly standard

| Wondering if anyone has information on percentage of components that we | can expect to "lose" during our SMT process. We are new to SMT, using | QUAD machines and feel we are losing to many parts during our process. | We are spending a lot of tou

| I am currently involved in a reliability project related to SMT QFP and TSSOP fine pitch solder joint reliability. I have decided to use a temp chamber for stress testing. Is there a test standard that covers this? I am also a bit unsre as to wheth

We have just go another batch of PCB's from our loaders, and some of the boards are severely warped. The boards are PCI cards and one of the boards is 9mm out at one end. The PCB is 210mm long and 4 layers. I am wondering if anyone knows what could
