Reducing production complexity: The right fastening solution from the design phase

heat sink

“The customer contacted us for the heat sink in the headlight body for Jaguar Land Rover. While working on their issue with the heat sink, we also pointed out a better solution for the fastening of the PCB,” said Klemens Freyinger, product manager of clinching technology.

ZKW Elektronik GmbH in Wiener Neustadt, a part of the global player of lighting technology for the automotive industry, was developing a new headlight body for Jaguar Land Rover in 2018.

In the headlight, the 3-part flex-rigid circuit board, which is bent twice, is to be installed in a heat sink. The original idea of ZKW Elektronik GmbH was to screw 3 circuit boards individually on each side. After receiving the inquiry, our Sales Engineer Lothar Preininger and our Product manager of clinching Klemens Freyinger looked into the detail of the headlight body design and suggested the use of PEM SMT Standoffs (SMTSO).

With the use of SMTSO fasteners, the 3-part Flex-rigid circuit board will only need to be fastened once and from one side only. That also means that two boards can be fastened with one fastening joint. On top of that, the SMTSO fasteners in the tape-and-reel packaging allow them to be installed by a pick-and-place machine like other fasteners elements without extra installation equipment and step. All the above-mentioned benefits largely reduce the number of fasteners needed, the installation time, and the installation equipment needed.
