Visteon Corporation has announced the automotive industry's first use of lead-free solder paste in a printed wiring board (PWB) electronic module. The company received approval from Ford to manufacture and supply its Passive Anti-Theft System (PATS) transceiver module using the lead-free solder.

The module uses a lead-free solder paste to replace the tin-lead (Sn-Pb) alloy solder. Visteon has been researching and developing this technology for several years and it has exceeded performance requirements in both laboratory analysis and in-vehicle testing.

Visteon says that the implementation of this technology is a significant step forward in the manufacturing and supply of lead-free electronics modules due to the anticipated restrictions on the use of all but trace amounts of lead in vehicle components in North America, Europe, and Japan.
