Current IssueThe Essential Guide to Surface Finishes
We go back to basics this month with a recount of a little history, and look forward to addressing the many challenges that high density, high frequency, adhesion, SI, and corrosion concerns for harsh environments bring to the fore. We compare and contrast surface finishes by type and application, take a hard look at the many iterations of gold plating, and address palladium as a surface finish.
It's Show Time!
In this month’s issue of PCB007 Magazine we reimagine the possibilities featuring stories all about IPC APEX EXPO 2025—covering what to look forward to, and what you don’t want to miss.
Fueling the Workforce Pipeline
We take a hard look at fueling the workforce pipeline, specifically at the early introduction of manufacturing concepts and business to young people in this issue of PCB007 Magazine.

Würth Elektronik Expands Its FPC Connector Family
October 30, 2024 | Würth ElektronikEstimated reading time: Less than a minute
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.
