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: 16
Claim 1
Independent Claim
133 words
The process of manufacturing a printed circuit board terminal having a hollow body with a section for receipt in a hole in a printed citcuit board and with a wall having inner and outer surfaces and a discontinuity in said wall which comprises applying a solder resist to only a portion of one face of a sheet metal blank and with said solder resist being thinner than the blank, severing said sheet metal blank in predetermined locations including said solder resist to form a terminal outline, and deforming the sheet metal of said outline to form said hollow body with said solder resist on said inner surface of said body and over only a portion of the length thereof that includes said section and with said discontinuity running at least over said section.
Claim 2
Dependent Claim
133 words
The process of manufacturing a printed circuit board terminal having a hollow body with a section for receipt in a hole in a printed citcuit board and with a wall having inner and outer surfaces and a discontinuity in said wall which comprises applying a solder resist to only a portion of one face of a sheet metal blank and with said solder resist being thinner than the blank, severing said sheet metal blank in predetermined locations including said solder resist to form a terminal outline, and deforming the sheet metal of said outline to form said hollow body with said solder resist on said inner surface of said body and over only a portion of the length thereof that includes said section and with said discontinuity running at least over said section.
Claim 3
Dependent Claim
31 words
The process set forth in claim 1 wherein the step of applying the solder resist comprises rolling a sheet of solder resistant metal against said sheet metal blank under substantial pressure.
Claim 4
Dependent Claim
25 words
The process set forth in claim 1 wherein the step of applying a solder resist comprises flashing a metal resist on said sheet metal blank.
Claim 5
Dependent Claim
26 words
The process set forth in claim 1 wherein the step of applying a solder resist comprises applying an organic solder resist to said sheet metal blank.
Claim 6
Dependent Claim
25 words
The process set forth in claim 1 wherein tbe step of applying a resist comprises adhesively applying a solder resist to said sheet metal blank.
Claim 7
Independent Claim
81 words
The method of making a female terminal which comprises selecting a sheet of resilient, deformable metal of predetermined thickness securing thereto a thinner solder resist on at least a part of one surface of said metal sheet that extends from one longitudinal edge thereof over a fractional part of the width thereof, and deforming the workpiece into a female terminal to present the solder resist in an internal area of the terminal which is adapted to surround an inserted male terminal.
Claim 8
Independent Claim
81 words
The method of making a female terminal which comprises selecting a sheet of resilient, deformable metal of predetermined thickness securing thereto a thinner solder resist on at least a part of one surface of said metal sheet that extends from one longitudinal edge thereof over a fractional part of the width thereof, and deforming the workpiece into a female terminal to present the solder resist in an internal area of the terminal which is adapted to surround an inserted male terminal.
Claim 9
Dependent Claim
20 words
The method set forth in claim 6 which comprises rolling the solder resist against said metal sheet under substantial pressure.
Claim 10
Dependent Claim
17 words

Claim 11
Dependent Claim
17 words
The method set forth in claim 6 which includes applying an organic resist to said metal sheet.
Claim 12
Dependent Claim
18 words
The method set forth in claim 6 which comprises adhesively securing a solder resist to said metal sheet.
Claim 13
Dependent Claim
43 words
The method set forth in claim 6 wherein the metal sheet comprises an elongated sheet having opposite longitudinally extending edges, wherein the solder resist is applied intermediate said edges, and including the further step of longitudinally severing said metal sheet intermediate said edges.
Claim 14
Dependent Claim
50 words
The method set forth in claim 6 including the further step of dipping the sheet including at least a part of the resist in an etchant, and then hot tin dipping the sheet to apply a conductive and solderable coating to said sheet and a part of said solder resist.
Claim 15
Dependent Claim
27 words
The process as set forth in claim 1 wherein the step of applying the resist comprises oxidizing a portion of the surface of the sheet metal blank.
Claim 16
Dependent Claim
20 words
The method as set forth in claim 6 which comprises oxidizing a portion of a surface of said metal sheet.
