Oh silver and its...improved solderability over tin / copper. BS if you ask me. Look to your flux and thermal profile for wetting spread. Ask yourself just how much "wetting spread" do you need to fill a barrel? I have the same 100% barrel fill

The blistering is around the plugging via. I can forward you the pic. For the plugging process, I'm not too sure how they plug. What is the correct practise for the plugging via. Now, what they did is. They will do a tenting process for both side.

Try vision type 12 for capacitors, this will give you much better acceptance in the vision inspection, since those are slightly rounded. Resistors works normally fine with vision type 10. If you have a component that is very hard to get pass the visi

I have a wave machine (offshore made) with internal spray fluxer configured with a conventional spray gun set up. In order to spray fluid (in this case, flux) I must set the air pressure at 0.3 mPA (43 PSI). At that pressure, my flux sprayer creates

Unfortunately, I don't have a copy of IPC-A-610 D on hand, however, I believe in IPC-610, this �floating height� between lead and pad has no maximum specification restriction. As long as there is no voiding, it is still acceptable for all 3 classes.
