Compliant Pin Interconnection

Interconnections between printed circuit boards can be made with improved reliability, less cost and greater convenience by using double-ended compliant pins for forming board junctions.

Referring to the figure, circuit boards 1 and 2 are joined at adjacent plated through-holes 3 by a double-ended compliant pin 4. The pin is formed with collar 5 to limit pin insertion and provide space for forced air cooling. Pin 4 is pressed into holes 3 and avoids flux entrapment and temperature stress encountered with soldering. Multiple pins can be inserted simultaneously and several boards can be stacked with this technique.
