Abstract

This design of interconnects require reliable robot placeable contacts which "se pc board area efficiently. As this contact design is purely surface mountable, it eliminates the need for it to go through the printed cir- cuit board. Without the need of through holes, the pcb area savings is particularly significant on multi-layer boards. Surface mounting then enables robot placement of the contacts to be easily achieved. The use of a coni- cal spring achieves a low-profile design as the spring could deflect down to its spring diameter dimension.

SURFACE-MOUNT LOW-PROFILE POGO-PIN CONTACT DESIGN

by K H. Chong

  This design of interconnects require reliable robot placeable contacts which "se pc board area efficiently. As this contact design is purely surface mountable, it eliminates the need for it to go through the printed cir- cuit board. Without the need of through holes, the pcb area savings is particularly significant on multi-layer boards. Surface mounting then enables robot placement of the contacts to be easily achieved. The use of a coni- cal spring achieves a low-profile design as the spring

could deflect down to its spring diameter dimension.

  The design consists of a sheet-metal stamped enclo- sure that houses a conical spring back-loading the con- tact plunger. The enclosure is reflow soldered on the pcb utilising the solder surface area for strength. The conical spring enables the maximum deflection to be achieved at a height lower than a typical compression spring.
