In general, it is safer to use a single alloy with a known composition and performance characteristics. If you need to change the alloy used in your selective soldering machine bath, it is advisable to consult with the manufacturer or a soldering exp

Dear proffessionals! Question is about this alloys - Sn99Cu07 and Sn100 (Sn100C,Sn100Ni+ etc.). Is it O'k to mix them? In my case to use Sn99Cu07 as addition to selective soldering machine bath with Sn100C? Main components are the same, but minor add

Sure it's conceivable that thin HASL can cause tombstoning. Harkening back to the ample discussion in the fine SMTnet Archives, tombstoning is caused by an imbalance in solder surface tension between the two pads of SMT component. The source of thi

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to
