Gold-plated FPC connector family expanded

The selection of connectors for FFC and FPC from Würth Elektronik is expanding. The manufacturer of electronic and electromechanical components now offers WR-FPC ZIF connectors (Zero Insertion Force) with locking mechanisms and featuring gold-plated contacts. Gold over nickel on the connector strip improves electrical conductivity, wear resistance, corrosion resistance, and reliability. The new variant is mainly aimed at connecting FPCs.

The mechanical properties and polarity of the gold-plated connectors are identical to the standard series with tin plating, so no design changes are necessary if a customer wishes to upgrade. In addition to enhanced conductivity and signal quality, the FPC connectors provide another advantage: FPCs usually have gold-plated contacts. The new connectors avoid mixing gold and tin in the transition zone. Gold and tin form an electrochemical series, which can cause corrosion and limit the service life of the connection. It is, therefore, recommended to ensure that gold is combined with gold and tin with tin on the contact surfaces.
