QFP soldering issue

Electronics Forum | Thu Jan 08 16:16:09 EST 2004 | Dean

My first concern would be the choice of solder paste you have. There are better chemistries out there that far exceed the capabilities of the 609 2. Yes, the part will partially float on the solder (assuming plastic qfp). Cross sectioning would sho

I will review some of the advantages/disadvantages of AOI vs. X-Ray one by one according to the main differences that you may find between them. * AOI uses optics that can "see" only visible elements. X-Ray can "see" hidden elements. There is a ve
