Reflow => Top side DIP => Bottom side glue => Bottom side SMT => Wave solder ... We couldn't keep the DIP clinch apparatus away from the bottom side SMT if we did the bottom side SMT prior to DIP.

Have you thought of contacting these people: http://www.solder.net/ I have a feeling they may be quite close to you geographically.

Rob, Even this Yank got that British humor. I guess the guys at Business Electronic Soldering Technologies are not very busy lately. All of these thinly veiled advertisements they are posting here just makes me not want to use them. Jerry

Hi, thanks for reply. Kapton tape is costly and it may create another handling issue. BTW can you share the thread for the cleaning process ?

Hi David, thanks for reply We did doing some study, most properly this problem was due to reflow process. Any thing that we can do for the reflow profile ? slow down the ramp up rate or .....

Yes, thanks for bringing up that point, DaveF. All polyimide tapes are not created equal, and in my experience Kapton has always worked for this application. The "better deal" has not, ever.

You don't clean contaminated gold fingers so much as you replace them. I once had the "cleaning" solution. It totally dissolved the gold fingers so that they could be replaced.

so you bend it to go in? Can you not let it lay flat? We run flex on carriers, but nothing that large. We also run 48inch long boards, but they are aluminum.

I don't have equipment that can handle this size of a board. Do you see any challenges on printing 48" board?
