Abstract
A method of coating an electronic component comprises applying a U.V. curable liquid resin containing a photoinitiator, rotating the coated component from its coating position, and passing the rotated component next to a source of U.V. radiation.
Claims8
A method of curing coated electronic components, where the coating is subject to withdrawal after application, comprising the steps:
- (A) placing an electronic component in a bath containing an ultraviolet radiation curable, liquid coating composition resin comprising a monoacrylate and a photoinitiator, to completely coat the electronic component;
- (B) removing the coated electronic component from the resin bath, necessarily causing a downward flow of the applied resin;
- (C) rotating the coated electronic component from its bath position to control the flow of resin resulting from removal from the bath;
- and
- (D) passing the rotated electronic component next to a source of ultraviolet radiation.

A method of curing protective coated electronic components having edges thereon, where the coating is subject to withdrawal from the edges after application, comprising the steps:
- (A) passing an electronic component having edges thereon through a bath containing an ultraviolet curable, liquid, polyester-monoacrylate coating composition containing photoinitiator, to completely coat the electronic component;
- (B) removing the coated electronic component from the resin bath, necessarily causing a downward flow of the applied resin with resulting resin withdrawal from the edges at the top of the electronic component;
- (C) rotating the coated electronic component to control the flow of resin resulting from removal from the bath;
- and
- (D) passing the rotated electronic component next to a source of ultraviolet radiation.
