We are investigating alternatives to HASL finishes for more dense PWBs. OSP is not a good choice because of low solid flux and possibly long shelf life. Immersion gold is expensive and so far has been more difficult to wave solder. Has anyone had

Thx to everyone who replied. we will be running single sided thru hole and double sided smt, 186 rosin flux cause they tell me it can take the heat needed for 18 layer pwbs. some long leads. also they are ordering in pallets to deal with the irregu

We have a product, with various PWBs, with over 600 parts each one (We are a low Volume/high mix company with an average component placement per PCB between 250 to 300 parts). This PWBs have 7 to 10, 20 mils pitch parts. We are having problems with o

Hi Well you already got good answers with some diversity, yet from what I read they are giving you the answers for Assembled PWBs, i.e. post solder or PWAs. I don't remember ever doing this for raw boards. For most of the current pwb finishes it se

I had parts replaced on SMT PWBs and the repair created measling defects. Reliability Question: Q1. Can measling be aggrevated or grow over time due to temperature cycling and moisture. Customer environment is -62C to +85C. Thank you Doug Hotal

We have been trying to flow some PWBs with pth that have foil on both the primary and secondary sides. What would be the best way to setup the wave solder machine to accomplish this task. for example (solder temp,conveyor angle,conveyor speed)

I have seen the 6.5 ug/sqin and we have a fab house using 6.4, but I have no definitive answer for today. I see some interesting discussion here which I can also follow up on.
