The number of contacts for each connector is from 2 to 10 poles. This pair of Preci-Dip connectors is an optimal solution to connect and stack printed circuit boards. Both carriers are made of high- temperature plastic and maintain the position of the contacts during the soldering operation. Carrier is used as a pick-and-place cap, allowing automatic positioning on the PCB. Cap is not foreseen to be removed after soldering. Both connectors can be supplied either in bulk or in a tape-and-reel packaging. The challenge was to develop a connector that will be soldered on a minimum PCB surface.

Main advantages of this connector are its small size; it can be soldered from underneath with optimal connection between two PCBs, with technology using a BeCu clip with 500 cycles guaranteed. The maximum current rating is 3 Amps.

The pair of connectors (socket connector and pin header) has originally been designed and developed for a connection between two LED lighting strips. Each strip is equipped on one end with a 2-way socket connector and on the other end with a pin header. The LED lighting strips are stackable. For this application, a connector with SMD solder tails at the back of the connector was not possible due to space limitation. This type of connectors can be used in many other applications where a board-to-board connection is needed.
