Abstract
It is aimed to provide a terminal capable of realizing a cost reduction while maintaining solder wettability. The terminal has a board connecting portion to be connected to a circuit board, and includes a base and a plating layer. The base has a plated surface covered by the plating layer and an exposed surface. The plating layer on the board connecting portion has a first inclined surface for covering a slope connecting the plated surface and the exposed surface.
Claims12
A terminal with a board connecting portion to be connected to a circuit board, comprising:
- a base;
- and
- a plating layer;
- wherein:
- the base has a plated surface covered by the plating layer and an exposed surface;
- the plating layer has a first inclined surface for covering a slope connecting the plated surface and the exposed surface in the board connecting portion;
- the board connecting portion has a rising surface rising at an angle from the exposed surface;
- the rising surface exposes the base;
- and
- the plating layer has a second inclined surface for covering a slope connecting the plated surface and the rising surface.
A terminal production method for producing a terminal, comprising:
- providing a plate material having opposite first and second surfaces
- applying plating to form first and second plating layers respectively on the first and second surfaces of the plate material to obtain a plated plate;
- stamping the plated plate to obtain a terminal piece having the first and second plated surfaces and an exposed surface extending between the first and second plated surfaces;
- and
- rolling the terminal piece at areas of the first and second plating layers adjacent the exposed surface to form first and second inclined plated surface areas that are inclined toward the exposed surface.
A terminal (30) with a board connecting portion (31) to be connected to a circuit board (10), comprising:
- a base (41) including:
- a first non-inclined surface (42A1) and a second non-inclined surface (4261) facing oppositely from one another,
- first inclined surfaces (42A2, 42A3, 42A4) extending from the first non-inclined surface (42A1) and second inclined surfaces (4262, 4263, 4263) extending from the second non-inclined surfaces (4261), and
- end surfaces (43A, 43B, 43C) extending from the first inclined surfaces (42A2, 42A3, 42A4) to the second inclined surfaces (42B2, 42B3, 42B3);
- and
- a plating layer (44A, 44B) covering the base (41) across the first and second non-inclined surfaces (42A1, 42B1) and the first and second inclined surfaces (42A2, 42A3, 42A4;
- 42B2, 42B3, 42B3);
- wherein:
- the base (41) is exposed at the end surfaces (43A, 43B, 43C) between the first inclined surfaces (42A2, 42A3, 42A4) and the second inclined surfaces (42B2, 42B3, 42B3);
- and
- at least a first of the exposed end surfaces (43A) defines a part of the board connecting portion (31) that is to be connected to a circuit board (10).
