Abstract
Z-axis pin connectors for interconnecting stacked printed circuit boards are formed from resilient material and have contact sections larger than cooperating through-plated holes formed in the boards. The pin connectors are drawn through the through-plated holes in the stacked circuit board, causing the contact section of the pin connector to frictionally engage the through-plated holes on at least two boards. Formation of pin connectors from a resilient thermoplastic material coated with a conductive layer is also disclosed.
