Flexible press fit pins for semiconductor packages and related methods
First Claim
1. A pin for a semiconductor package, comprising:
- an upper contact portion comprising a contact surface configured to mechanically and electrically couple with a pin receiver;
a lower portion comprising a single vertical stop and at least two curved legs;
a horizontal base coupled directly to the at least two curved legs and configured to be soldered to a substrate to mechanically and electrically couple the pin to the substrate, the horizontal base having an upper contact surface and the horizontal base extending substantially perpendicularly beyond a width of the upper contact portion, and;
a gap between a bottom contact surface of the single vertical stop and the upper contact surface of the horizontal base;
wherein the at least two curved legs are configured to flex to allow the bottom contact surface of the single vertical stop to move toward the upper contact surface of the horizontal base in response to a pressure applied to the pin along a direction collinear with a longest length of the pin toward the upper contact surface, and;
wherein the single vertical stop is configured to stop movement of the pin when the bottom contact surface contacts the upper contact surface.

Abstract
A pin for a semiconductor package includes an upper contact portion having a contact surface configured to mechanically and electrically couple with a pin receiver. A lower portion of the pin is configured to flex to allow an upper portion of the pin to move towards an upper contact surface of a horizontal base of the pin in response to a pressure applied along a direction collinear with a longest length of the pin towards the upper contact surface of the horizontal base when the pin is inserted into a pin receiver. Some implementations of pins include a vertical stop to stop movement of the pin when a surface of the vertical stop contacts the upper contact surface of the horizontal base. Varying implementations of pins include: two curved legs and one vertical stop; two partially curved legs and no vertical stop, and; a single leg bent into an N-shape.

10. A pin for a semiconductor package, comprising:
-
an upper contact portion comprising a contact surface configured to mechanically and electrically couple with a pin receiver; a lower portion bent into only one N-shape, wherein a first bend of the N-shape couples a first section of the N-shape into a slanted section of the N-shape and a second bend couples the slanted section of the N-shape to a second section of the N-shape substantially parallel with the first section of the N-shape; a horizontal base coupled directly to the second section of the N-shape, the horizontal base configured to be soldered to a substrate to mechanically and electrically couple the pin to the substrate, the horizontal base having an upper contact surface and the horizontal base extending substantially perpendicularly beyond a width of the upper contact portion; and a gap between a lower contact surface of the first bend and the upper contact surface of the horizontal base; wherein the N-shape is configured to flex to allow the lower contact surface to move toward the upper contact surface in response to a pressure applied to the pin along a direction collinear with a longest length of the pin toward the upper contact surface, and; wherein the N-shape is configured to stop flexing after the N-shape has bent sufficiently to allow the lower contact surface to contact the upper contact surface. - View Dependent Claims (11, 12, 13, 14)
