This might be a trival mundane suggestion but try to use non conductive plate to hold components. Probably even made of the pallet material. I am sure your pallet fabricator will have tons of scrap and he can help you find one. T

Yes Davef, storage condition and long time remaining on shelf could effect pealing strength, but we experimented that by using Polystirene Carrier Tape also this problem was reduced almost to zero. Df, If I am not wrong when you talk about pr

Can static built up on the surface of a reel be removed?

Electronics Forum | Tue Jun 21 17:27:10 EDT 2022 | kojotssss

Offcourse, RH is between 47-50%. The cause of problem is that the one of the embossed carrier reels/package materials coming from supplier static charged. Material now is like insulating, not dissipative or conductive. Example: https://drive.google.

Kevin: We know of no handy approach to developing recipes. * Certainly programs provided by profiler suppliers give you a good first pass, based on your oven and solder paste. * Second pass in developing your recipe comes through trail and error chan

Via filling methods are: * Tenting * Plugging * Capping * Flooding Tented Via. A via covered with dry film soldermask; the via is not filled. When tenting from both sides there may be issues with trapped air that expands during mass soldering. Plug
