Terminal pin suitable for use in BTB & WTB applications


A terminal pin suitable for use in a variety of BTB and WTB applications, has been introduce by Mill-Max. It features a compliant press-fit tail, slotted head and a press-fit feature on the barrel of the pin, providing a reliable connection.

The 3622-0-32-15-00-00-03-0 pin is designed to be a solution for interconnect configurations. The pins can be used individually or packaged in customer specified connector arrangements. The solderless press-fit tail allows the pins to be staked into PCB holes and have 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 1.02mm ±0.0762 mm plated-through-holes and will provide a gas tight connection.

The pin can be used as an edge board mount pin by fitting the board into the slotted end of the pin; this facilitates right angle BTB mating such as daughter card to mother board. When used for board edge connections, the PCB 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 1.57mm.

The pin can also be used for WTB 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. Since there is no soldering operation required to make the secure electrical connection to the board, there is no concern about compromising this connection during the soldering of wires. The slot will accept up to 16AWG stranded wire. It is available with standard 0.254μm gold plating.
