Hi Dave, Thanks on your feedback, May I know the how's the contributing of Moisture content of bare board and the Thickness of the copper plating in the PTH to the solder ball and solder splash during hand soldering process ?

Electronics Forum | Sat Jul 25 08:47:25 EDT 2009 | davef

Both "moisture content of bare board" and the "thickness of the copper plating in the PTH" are related to each other. As you heat the solder connection, moisture in the board boils and out-gasses through the solder connection. Plating with the proper

Gyver: Lemme take a wack [if you�ll excuse the expression, given direction of the later discussion] at your questions. Q1. Will the baking of BGA or PCB cause more oxidation before the SMT process? A1. It certainly will not cause less oxidation,

Prof. Whoopee - amazing facts that you find on your 3-D BB, it has completely confounded my comrade, Chumley. Plainly spoken that around the SF Bay Area a.k.a. Silicon Valley(ever hear of the famous SF Fog?)during the winter months, near the coast a

We're looking at redesigning our stencils to facilitate better (well, it's pretty much non-existant, so any improvement is a big leap) release from fine pitch apertures. Currently we have perpendicular walled laser cut apertures. We'll be having
