Soldered interconnect for a printed circuit board having an angular radial feature
View Patent ↗According to exemplary embodiments, a tapered surface interconnect is formed on a printed circuit board (PCB). A compliant pin of an electrical connector may be coupled to the tapered surface interconnect and soldered thereto. The surface interconnect may be formed by drilling through one or more layers of the PCB. The depth of the surface interconnect may be shorter than a height or a thickness of the PCB. The surface interconnect may have a tapered side wall to allow for a better fit with a tapered compliant pin. The inclination of the side wall of the surface interconnect may be linear or concave. The intersection between the tapered sidewall and the bottom of the surface interconnect may be rounded to minimize pin insertion issues and may allow for easier solder flux evacuation. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.
1. An electrical compliant pin connector comprising:
a connector body; and
a compliant pin provided at a first end of the connector body, wherein the connection pin includes:
a tapered end having a tapered surface, having dimensions for a substantially complete insertion below a top surface of a printed circuit board and having a height of up to 0.007 inches; and
a groove that is a continuous divot formed directly above the tapered end of the compliant pin around a circumference of the pin to form a neck.
2. The electrical connector of claim 1 , wherein the connection pin further includes an anchoring feature at an extremity of the tapered end.
3. The electrical connector of claim 1 , wherein a corset anchor is coupled to an extremity of the tapered end.
4. An electrical compliant pin connector, comprising:
a connector body; and
a compliant pin provided at a first end of the connector body, wherein the connector pin includes:
a tapered end having a tapered surface, having dimensions for a substantially complete insertion below a top surface of a printed circuit board and having a height of up to 0.007 inches; and
a groove formed directly above the tapered end of the compliant pin that is a continuous divot around a circumference of the compliant pin to form a neck.
