Waldenburg (Germany) – The selection of connectors for flat flexible cables (FFC) and flexible printed circuits (FPC) from Würth Elektronik is getting even larger. The manufacturer of electronic and electromechanical components now offers WR-FPC ZIF connectors (Zero Insertion Force) with locking mechanism, 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 primarily aimed at connecting flexible printed circuits.
The mechanical properties and polarity of the gold-plated connectors are identical to the standard series with tin plating, so no design changes are required if a customer wishes to upgrade. In addition to improved conductivity and signal quality, the FPC connectors offer 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.
The FPC connectors with gold-plated contacts are now available.
