Abstract

A solder masking support plate covers all the circuit except the selected areas which are to be exposed to solder. A number of spring-loaded plungers arranged in holes in a pressure plate resiliently hold the flexible circuit against the masking plate around each area to be exposed to the solder. Used for soldering printed circuits where the substrate is made from flexible plastic. The plungers press the circuit against the support plate eliminating a possible separation between the support plate and the flexible circuit if the support plate warps thus preventing voids or skips. Pressing the flexible circuit around the areas to be soldered makes a kind of seal which prevents solder from penetrating or spreading outside the areas defined by the apertures in the masking plate.
