PCB threaded connections using press-fit technology

Würth Elektronik offers its 'REDCUBE PRESS-FIT for Automotive', a new range of threaded connections optimised for the automotive industry. The robust components can carry currents of up to 250A and are manufactured according to particularly stringent quality standards.

The automotive industry includes some of the most demanding customers. Reworked products are not acceptable. High requirements apply to the components used, especially for current-carrying connections. They must be mechanically stable, highly conductive, and not thermally stress the circuit board.

The company now serves this demanding market with its new screw connectors for circuit board assembly utilising press-fit technology. The process provides an even contact between the pin and the copper layer, particularly on PCBs with very thick coatings, and offers greater reliability and stability than soldering. The new connectors allow a gas-tight and extremely strong mechanical connection. The contact resistance for the new automotive series is less than 200µOhm.

Three variants are available:

WE-PFIFUA with internal thread (full plain automotive).

WE-PFEFUA with external thread (automotive).

WE-PFICFA with internal thread (circumference automotive).

Each connector is available in the thread sizes M3, M4, M5, M6 and M8.

Every component is visually inspected for dimensional accuracy throughout manufacture. The pins are particularly robust to stop bending during transport or assembly. This ensures consistently high-quality production results. REDCUBE PRESS-FIT connectors made from RoHS-compliant CuZn39Pb3 alloy can be pressed in without thermally stressing the PCB.
