With a solder paste inspection system, you measure the volumes, see how consistent they are, see what the transfer ratio is and you can make a much, much more accurate comparison and use statistical analysis to make a choice. Phil And as far as an in-process tool, look at the number...

Method and device for producing an electronic circuit arrangement with uniform solder residues when transferring solder pasteA method for producing an electronic circuit device includes a repair step in which, in a case where a semiconductor device once mounted on a wiring board is defective, the ...
• Solder bridging between pads In the process of ICT, probability of defects mentioned above is relatively proportional to severity of issues. Slightly insufficient solder paste will seldom lead to defects while absence of solder paste, however, will almost lead to defects during ICT. Insufficien...
Basically, we calculate the surface area of the lead of the component or the ball to the area when it is collapsed that is in contact with the solder paste. In other words, tangent. And for each of the inter-connects, leads, balls, whatever. Or in the case of a QFN, we haven't ...

A lead-free solder joint requires more energy than a lead-containing joint under the same conditions. This applies to all soldering processes, regardless of whether you use solder wire or solder paste. Since the amount of energy required is higher, the heat transfer to the soldering point must...
