215 to 220 deg.C peak reflow. We bake then store all PCB's in low humidity cabinets (appox. 3% RH) prior to running.

We are recieving many QFN's in Tubes instead of trays and tape. Does anyone have luck with these in a tube feeder, or vib plate? We cant justify to order a full reel because the cost of the part.

I've got specialized tooling I'm building for SMT processing. It requires a 0.125" thick sheet of high temp. silicon rubber cut to shape. Does anyone know of someone who can cut silicon sheets to a specific pattern/design?

I would also look at Orion Industries. They are a power member and help support this forum... http://www.orionind.com.

We are going to be evaluating a Seica firefly laser soldering system and I was wondering if anyone had any feedback on their machines? Thanks

As a distributor we sell very little SN100C for SMT, we sell far more SAC305 for SMT. The higher temperatures are the reasons.

3-5% is extremely high. Think of that in terms of DPMO. 5% fallout would be a 50000 DPMO. That's not acceptable for most people.

Two pictures. Dark circles around solder joints. leaded solder, water soluble flux, selective soldering and seeing these dark lines circling around solder joints. Can not remove this either. Any idea what is making this occur??? See attached photos

We do selective soldering here so if you attach the pictures I might be able to offer some suggestions.
