RAST 2.5 IMS [direct connectors for Aluminum-PCBs]
Automotive electronics increasingly require the
heat produced from electronic components to
be dissipated in order to improve the life and
functionality of modern parts. Especially highpower LEDs for vehicle headlights demand an
optimized heat management for tight installation spaces.
Insulated Metal Substrate (IMS) is used more and
more for printed circuit boards, with aluminum
being the primary thermoconductive substrate to
which dielectric and copper traces are applied.
As a pioneer in the field of RAST connectors we
have developed a direct connector that secures the
safe single-sided mating with an aluminum PCB
edge. Its mating face is based on the versatile 2.5
RAST connectors which can be processed on fullyautomatic harnessing equipment and whose proven record sees it used in millions of vehicles.
