Bob Willis (was the first I knew of) that has a splatter test that can be performed over a ceramic hot plate or the like. The concept is pretty straight forward, using a zoned circle, users can introduce the solder wire at a consistent rate and coun

Davef, Thank you. I wonder if you have ever faced with concrete layer thickness selection for SMT shops? All I have found refers to metal treatment shops (primarily milling & drilling). 6" concrete is thick enough for them to stabilize milling machi
