Mill-Max Multi-Purpose Terminal Pin

By News Release | June 22, 2015

The Mill-Max multi-purpose terminal pin offers a press-fit tail, slotted head, and an additional press-fit feature on the barrel of the pin for reliable connection options.

Mill-MaxMill-Max Multi-Purpose Terminal Pin introduced a new terminal pin suitable for use in a variety of board-to-board and wire-to-board applications. It features a compliant press-fit tail, slotted head, and an additional press-fit feature on the barrel of the pin to provide functional, versatile, and reliable connection options.

The new 3622-0-32-15-00-00-03-0 pin is designed to be a versatile solution for some popular interconnect configurations. The pins can be used individually or they can be packaged in customer-specified connector arrangements. The solderless press-fit tail allows the pins to be staked into printed circuit board holes for soldering operations on the slotted end of the pin without compromising the connection to the board. The compliant press-fit tail is designed to work with standard .040″ (1.02mm) +/- .003″ (.0762mm) plated through-holes and will provide a gas-tight connection.

The 3622 can be used as an edge-board-mount pin by fitting the board into the slotted end of the pin; this facilitates right-angle board-to-board mating such as daughtercard-to-motherboard. When used for board-edge connections, the printed circuit board is slipped into the slot and soldered; this may be done before or after the compliant tails are pressed into the adjoining board. The slot will accept board thicknesses up to .062″ (1.57 mm)*.

The 3622 can also be used for wire-to-board applications where a permanent termination of wires, for power or signal transmission, is required. Once the pin is pressed into the board, the wire can be placed into the slot and soldered. The slot will accept up to #16 AWG stranded wire.

The 3622 slotted, compliant tail terminal is a versatile, robust, and convenient solution for board-to-board and wire-to-board interconnect applications. Like all Mill-Max pins, the 3622 is precision-machined to the highest quality and consistency. It is available with standard 10 micro inches gold plating (thicker gold plating available upon request).

* The machining process produces an arc through the slot. When using multiple pins in line, the slots need to be uniformly oriented to maximize usable slot width.
