Is it possible you could simply over print to achieve the same paste volume? Supply me the numbers and I will do the calculation for you. Cheers

Don't overlook the SMTnet Archives there is quite a bit of experience there from people slopping solder on their gold fingers.

A question for all you wavesoldering buffs out there ? What i'd like to know is what causes the bulb-shape type joints around chip components when flowed over the wave ? which wavesoldering process parameter contributes to this type of defect & how

It sounds like the temperature of wave is a little lower. It should be 245~250 deg.C for solder Sn63/Pb37.
