Garbsen, June 2008 – TRW Automotive builds more functions into car steering wheels. Using the LPKF-LDS® method enables TRW Automotive to cut costs at the same time. A laser is used to lay electronic circuits directly onto three dimensional plastic parts, also known as moulded interconnect devices (MIDs). This eliminates connectors, PCBs and cable harnesses – to save assembly costs and create room for new functions.
The LPKF-LDS® method beats conventional methods thanks in particular to the short process chain, low production costs, and fine structural resolution.
LPKF Laser & Electronics AG produces machines and laser systems used in electronics manufacturing, the automotive industry and the production of solar cells. Approx. 75 per cent of its turnover is generated by exports. The company has approx. 360 staff around the world.
