Yes I stand corrected............we'll see what the future holds for them and hopefully they can survive. I know they've been shopping this unit around for some time.

Hi All, I have some question about expired solder paste. What would be some of the effects regarding assembly quality. Is there any changes in flux composition toward the end of shelf life? Thanks in advance for any replies.

All of what Dave says is spot on. I suspect that the most likely corresponding defects on your assemblies would be poor wetting and insufficient solder.

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.
