Abstract
Abstract A solder resist, i.e., a material that is not wet by and hence not adhered to by solder is applied to a portion of a sheet metal blank. The sheet metal blank is stamped and formed to produce a substantially cylindrical female terminal for receipt of a plugin male terminal as of a solid state device. The terminal is flow soldered in place in a printed circuit board, and the solder resist prevents solder from adhering in areas where it would adversely affect operability of the female terminal.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
121 words
A terminal for printed circuit boards comprising a hollow body having a wall with inner and outer surfaces and having a discontinuity in said wall, said body being adapted to be inserted through a hole in a printed circuit board including printed circuit wiring thereon and soldered in place, an upper open portion integral with said body and adapted detachably to receive a complementary terminal which when in the body is surrounded by said inner surface, and a solder resist on said inner surface at least in the region that is adapted to surround said complementary terminal to prevent at least in said region the adherence of solder that may flow through said discontinuity when the terminal is soldered in place.
Claim 2
Dependent Claim
121 words
A terminal for printed circuit boards comprising a hollow body having a wall with inner and outer surfaces and having a discontinuity in said wall, said body being adapted to be inserted through a hole in a printed circuit board including printed circuit wiring thereon and soldered in place, an upper open portion integral with said body and adapted detachably to receive a complementary terminal which when in the body is surrounded by said inner surface, and a solder resist on said inner surface at least in the region that is adapted to surround said complementary terminal to prevent at least in said region the adherence of solder that may flow through said discontinuity when the terminal is soldered in place.
Claim 3
Dependent Claim
106 words
