Typically, Sn/Pb solders are used to preserve solderability on leaded and leadless SMT components. Are other finishes (such as those used in PCB manufacturing e.g. Sn, NiAu, OSP's, etc.) frowned upon by PCB stuffers and their customers? I am intere

Hi, For hand placement you should see about 150-200 ppm of errors (solder, placement, values etc) on a board populated of types such as 1206, 0805, SOT, Tantalum etc. . As for solely wrong components (component at wrong location) you can usualy redu

Chrys: Funny that you mention that, but here at my company, our oven is blamed on almost everything: skewing, tombstoning, solder shorts, etc.... In fact, we often have to tell the supervisors, "It's not the oven because we don't turn the skewing

Chrys and C.K. (or Little K from what I'm told), Where "I" work at, our fine management staff has informed us of "Smart Solder"! Not sure who makes it, but they claim it will make all your soldering problems go away. I'll send ya more info on it

Before changing solder pastes or jumping through too many hoops, check the melting point of the 100 Sn (pure tin) connection. According to Kester, the melting point of 100Sn solder paste is 232 degrees C. If you do not reach that temperature, you wi
