Yano, at lot this discussion is kinda school boy theory. Other issues are: * Soldering time * Corrosion [did we say that already?] * Safety [ie, personnel, plant, environment] * Cost of ownership

Hi Everyone, I am just curious, is there a guidline that people follow for choosing their lead-free solder paste? In other words, how do people know whether they should use Indium alloy, or Castin (Sn/Ag/Cu), or whatever else? Thanks

The temp is not an issue with selective soldering as the SN100C can be used at the same temp we used for tin lead. 260C. Some are using a higher temp, we did not notice any difference in the results with a higher temp. Most people run thier waves a

On average there are about 3 parts per board that get hand placed (x24 is 72 parts per panel). One of these parts is a big 1W resistor that cannot fit on our axial machine. We also have a Zener Diode that needs to be hand placed because its leads are

From what I see, you have a couple of options... 1. Hand solder the secondary side LED's. This is only a good option if you're going to be at low-ish volumes. Higher volumes tend to necessitate more automation to reduce production costs. However
