High temp solder is the best, but your profiler manufacturer will have some type of adhesive. I know KIC does.

More often than not lately, we use Al tape [like Brian W mentioned in a recent thread].

Dave, I use Dexter Hysol epoxy 9340 gray. It's a two part epoxy kit. Thermally conductive and electrically insulative. Cures in about 10 minutes at 100C. Terry

I'm trying to find information/articles describing the effects of temp and humidity on solder paste. Just recently we have gone through a change outside temperature and humdidty and have notice solderabilty problems with smt boards.

The size i had changed from 55 x 20 mils to 42 x 20 mils. The component size i have is 40 x 20 mils ( 1mm x 0.5mm ).

Profiles design is primarily determined by oven geometry, paste specifications and component thermal limitations. This means that no one "standard" profile exists for all production. A free profile planning utility can be quickly downloaded from

Consider the profile recommended by your solder paste manufacturer to be the starting point to begin tailoring ramp rate, dwell times, and temperature excursions to meet the requirements of your boad design, the capabilities of your components, and t

Can you recommend a good material to put in the cleaner for both water soluble AND no clean residues? Mike mweekes@phoeintl.com

Just a guess-- Could you be seeing the nickel under the gold plating because you are removing some of the Gold with the Kapton Tape ? This should be easy to verify. Otherwise it sounds like things are pretty much covered.
