ABSTRACT:
Sacrificial coatings are applied to the rounded ends of the flattened spiral laminates for wound film capacitors. The coated laminates are positioned between tapes masking their flat surfaces. The end faces of those laminates are then sprayed with the schoopage metal and the laminates are subsequently tumbled to remove the coatings and any overspray appearing on their rounded surfaces.
