"OK. If the connection doesn't look like I expect it to look, how do I know that the metallurgy is correct?" Comments are: * There are no pictures that will get you though this. * You should expect that gold that is dissolved in Pb/Sn solder to make

Hello everyone out there in the SMT world. I have a dilema I'm currently running a board that has 3 csp's with a .75 mm. ball pitch and .3mm ball size. And 2 qfp's-160. The stencil is 4 mils thick and I'm using a 63/37 solder paste. My reflow prof

This paper describes the results of an intensive whisker formation study on Pb-free assemblies with different levels of cleanliness. Thirteen types of as-received surface-mount and pin-through-hole components were cleaned and intentionally contaminated with solutions containing chloride, sulfate, bromide, and nitrate. Then the parts were assembled on double-sided boards that were also cleaned or intentionally contaminated with three fluxes having different halide contents. The assemblies were subjected to high-temperature/high-humidity testing (85_C/85% RH). Periodic examination found that contamination triggered whisker formation on both exposed tin and solder fillets. Whisker occurrence and parameters depending on the type and level of contamination are discussed. Cross-sections were used to assess the metallurgical aspects of whisker formation and the microstructural changes occurring during corrosion.
