Board to board connectors


Board to Board Connector

Board to board connectors provide the electrical connection from PBCs to other PCBs. Relevant factors for choosing the right connection include the number of poles, geometric size, quantities to be transmitted such as current, voltage or data rate. In addition, the arrangement of the PCBs to each other is decisive for the optimal interface. HARTING offers solutions for all possible PCB arrangements - extender card, mezzanine, mother to daughter card as well as ribbon cable connections.

Extender Card Connection


Device Connectivity PCB Connectors B2B Extender Card.psd

Extender Card describes the arrangement of two or more printed circuit boards in one plane next to each other. The necessary connectors are called angled variants. Their contacts are mounted vertically on the PCB and then describe a 90 degree arc. In this arrangement, the connector is positioned at one of the edges of the PCB and the mating face points away from the PCB.

Mezzanine Connection


Mezzanine describes the arrangement of two or more PCBs at least partially flat on top of each other. Both connectors protrude vertically from the flat side of their PCB and connect in the space between them. The distance is determined by the height of both connectors and the possible overmating area.

Motherboard to daughtercard Connection


Device Connectivity PCB Connectors B2B Motherboard to Daughtercard.psd

Motherboard to Daughtercard describes the arrangement of two or more PCBs in which one of the two PCBs is perpendicular to the surface of the other. In this arrangement, one connector is oriented perpendicular to the PCB and can be positioned almost freely on the surface of the PCB. The connector of the second or additional PCBs has a 90 degree angled design on the edge of the PCB. This arrangement is often used in racks where a large PCB forms the mothercard on which the daughtercards are inserted vertically via a rack rail.

Via Cable


Ribbon cables are used to connect PCBs when the distance to be bridged is too great for one of the other connections, with connector to connector. Ribbon cables can also be used when the possible routing of both boards makes another connection impossible.
