INEXPENSIVE AND EASIER TO ASSEMBLE
Besides a broad range of flat flexible cables (FFCs) and lockable ZIF (Zero Insertion Force) plugconnectors, Würth Elektronik now also offers the LIF (Low InsertionForce) connector WR-FPC.
Small and flexible flat-ribbon cables are widely used in LCD screens,board-to-board connections for medical equipment, test and measurementdevices, industrial applications, entertainment electronics, and the
broadest conceivable range of other types of devices. In many of theseapplications, it’s not important to have a vibration-free interlockfor the plug-in connector. For such applications, Würth Elektronik nowoffers the more inexpensive and easier-to-assemble solution of an LIFconnector. Fully suited for SMT pick-and-place assembly systems, theWR-FPCs in the 1-mm grid format are available in a variety of versions,from 4 to 30 pins, in horizontal and vertical plug-in directions.
Besides serving as sockets for flat flexible cables, they are alsointended for use as connectors for flexible printed circuit boards –hence the designation FPC. The rated current is 1 A, the operatingvoltage 125 V. To ensure a high degree of elasticity, low wear and tear,and a low resistance (30 mΩ), Würth Elektronik has selected phosphorbronze as the material for the contacts. The connectors have anundercoat of nickel to prevent the so-called tin whisker phenomenon.
To enable development teams and small companies to put these products touse more easily (just as for the entire range of FFC/FPC items), thesenew WR-FPC low-insertion-force connectors are offered ex stock incomponent belts without a minimum order volume. Free-of-charge samplescan also be supplied on request.
