The need to prebake boards to remove moisture from the board [to prevent voiding] prior to wave soldering is driven by the thickness of through hole plating. * 1 thou [25um] or greater requires no prebaking * LT 1 thou [25um] requires prebaking

Hi, I am also facing the same probelm. I assembly a substrate with a thickness of 0.30mm and the board warp after reflow. If I bake the substrate at 125 Deg C for 2 hours will it help to solve this problem? Thanks

In our house we have had some of our BGA's reballed because it was a lead-free part and wanted to place on a leaded assembly. Hope this helps.

Good Morning, We are seeing an increased number of our customers that specify a Pb-Free BGA when the rest of the board assembly is SnPb. Of course when we reflow at the SnPb profiles, we don't always get a properly collapsed BGA. So we end up rewor

I once took a pair of binoculars and stared at a wave solder for over an hour.

Russ, Take a look here: http://www.geigercounters.com/Monitor4.htm You can buy one already assembled, or buy the kit and build it yourself. I've built two of these kits, they work just fine.

We produce High mix very low volume Military assemblies. So a typical order mya be for 50 pcb's, at a 5 up array. Do you work in the fab shop? Scott

There is no actual book on HOW to program equipment. The books that Bob mentions all deal with the theory of SMT, and doesn't go into the nuts and bolts of how to program a machine.
