Most of the design considerations will be for the wave soldering of the SMT parts. Have you considered selective soldering pallets or masking as an alternative? One problem I have seen with the epoxy process is parts that are high off the board and t

Paul We don't like to mix metals on press fits. Yano, we do gold on gold or solder on solder, but we don't mix metals [except with imm silver / tin] to avoid electrochemical corrosion. Is that bad information or does AMP think that's not a problem

I am interested in your experience with dross reclamation equipment. What percent solder can be recovered? Who makes a good system? Thanks, Kevin

My company is looking into selling off our old solder paste, Is there anyone who currently does this and can offer some comparitive prices/pound.

Does a third solder reflow compromise component and solder reliability? We find that the only way to rework a particular BGA without warpage is to reflow the entire board.

I am looking at dispensing solder paste using a Fuji GLV glue dispenser. This is to enable us to produce prototype pcb's without the need to purchase a stencil. Has anybody tried this before? If so what problems should I expect to encounter.

The FGLV has a air pressure displacement valve, which is designed for adhesives. A positive displacement valve is better suited for solder pastes. Check with Fuji to see if they offer optional valves.

In printing,the thickness of solder paste perpendicular to the Squegge direction is always lower 1 mil than that parallel to the Squegge direction,so Insufficient Solder may occur.I think you may slow printing speed or widen appertures to resolve it.

Hi: I'm looking for input from anyone who has experience assembling the MLP package on PCBs. We are experiencing solder opens after assembly, and I'm curious to see how others are processing these critters. The part we are using is a Semtech SH3000

Pete I'm not very informed about it but from the things I red today - 2D inspection : solder component solder joints x-ray and what ever type exsist.
