Surface mount 3-point printed circuit board (PCB) sockets cover pin sizes from 0.80 to 1.90 millimeters for automated production processes

Electronic devices and modules usually require replacement over time. Soldering temperatures also introduce a risk of early failure of these modules. Direct soldering onto the printed circuit board (PCB) is inadvisable. Removal of a failed or damaged module can be difficult and could result in scrappage of the whole board.

To tackle this problem, Harwin has announced further additions to its Sycamore Contact series of surface mount PCB sockets. While this series was initially capable of accommodating 1 and 1.5-mm diameter contact pins, it now covers pin sizes from 0.80 to 1.90 mm. According to the company, the product now allows odd-form devices/modules that are not suited to regularly-spaced socket strip arrangements to be attached without any future inconvenience, should removal be required at a later stage.

“Whereas other contact solutions of this kind only comprise two points of contact to the mating pin, making them vulnerable to exposure from vibrational forces, the new design of the Sycamore Contact gives engineers access to three contact points. This markedly improves operational stability, as well as delivering stronger pin retention and heightened levels of signal integrity”, Harwin explained in the announcement.

Product specs:

  • Available in both top-entry and bottom-entry configurations, these sockets have a current rating of 6A and a 15 mΩ (maximum) contact resistance.
  • The products come in sturdy construction, which uses beryllium copper with gold plating, and provide upto 500 mating cycles.
  • The sockets exhibit an operational temperature range spanning from -50° to 125°C.
  • As these components can be supplied in a tape-and-reel format, they are highly suited to automated production processes with the surface mount placement feet also serving as the pickup areas for pick-and-place machinery
