Hi, Thanks for your reply. I run 2 boards, using the same paste, thermal profile and the same method of aqueous cleaning, 1st is a Topline test board with topline BGA (BGA 272 with 1.27 Pitch) and the 2nd is our product PCB with our BGA from Motoro

Hi Russ, Thanks for the reply. No this is 856, I sprayed some on boards just to try it out and noticed it dries very quickly also but if its soldered right away as would be the case in the machine, it's fine. I believe I tried some 857 and found th

Thanks davef. Your comments are well taken. How about the trays transporting boards from one station to another or staging at WIP Kanban? It��s easy enough to segregate rework stations and tools. Trays are used thru out the plant without segregation

Degeaser isn't a good chemical to use either cause it leaves a residue so don't use it. alcohol works good. Not sure why everyone thinks it blows up. heck i remeber back in the day when I hade 24 inch foam fluxers bubbling flux and alcohol (IPA no

I feared so. The only thing to be done is to tell the PCB manufacturer to increase the Thermal cure so dont set the oven to 150C but to 170C and actually measure the middle board and once it hits 155C then give it an hour cure from then. Also insist

Some of this was copped from Fred. There are numerous package types that now fall under the rubric of land grid array [LGA]. Land grid devices [ie, Bumped Chip Carrier� [BCC], LGA, Quad Flat-pack No-lead [QFN], MicroLeadFrame�, etc] are essentially

Steve, I wave solder most if not all our boards with selective wave pallets. I did not catch if the solder balls were on top of the board or on the bottom but that will make a difference on what to do to get rid of them. Pallets are good and bad. On
