No adhesive? Then how about 2 different solder pastes? Higher melting temp for the first side, lower for the second.

All, What controls do you have in place for PCB moisture control? If you had a kit of 400 and you ran out of a part which wasnot due in until 6 weeks- do you store the boards in a dry cabinet ? Vacuum seal and store on a rack? Alan...

Thanks Dave. We are UK based which is why we are still allowed to use Trike and our product is for an aerospace application so changing a cleaning chemical is much easier than requalifying a new flux. This was pretty much what I thought my options

Ooops sorry! Has anyone ever had a problem with using FR4 for a burn-in board? We suggested using Nelco or getek, but will FR4 have any problems in the assembly area through the solder wave?

nope it will not, I am sure that an FR-4 board has been wave soldered sometime in history Russ

Does anyone have a motor frequency inverter(driver) for an ERSA Versaflow, that you can sell me? It says "Seidel" and then "digifas 7200". I know this is a long shot, but even if it's used I'll take it.

Funny that you post this, but I just had one of these go bad on me. ERSA Field Service came in and replaced it.

Using a meter to check a BGA connection to the board, there will be other parts of the circuit involved. Sounds like a bad batch of parts.

We have not had very much luck hand dispensing on small pads. It can be done but you will most likely have bridging and insufficients.

If it's only 30 boards why not just get a stencil foil and hand print it? It's a piece of cake...
