The ZIF (zero insertion force) connector is one of several connection options for flexible printed circuit (FPC) connector attachment. ZIF connectors are ideal for small centerline spacing requirements that make larger wire-to-board interconnects not practical. With various pitch and circuit size options, ZIFs offer easy actuation and secure cable retention between the FFC-FPC and the connector terminals.
ZIF Connection Advantages:
- Wear – Zero Insertion Force allows for cycling with minimal wear
- Strength – Maximum cable retention in the smallest size
- Insertion – Easy insertion of very thin, flexible cables
To prevent ZIF contact miss-alignment, laser routing of the ZIF circuit demand precision tolerances of +/- 25um. With integrated vision alignment, MLT’s ZIF cuts hold the most challenging ZIF requirements. Many panel or board layouts require the ZIF leads to extend beyond the routing path to facilitate testing or plating prior to excising. Even with ZIF copper contacts in the rout path, MLT’s hybrid laser processing can process the metal and metal-free flex areas seamlessly.
To meet the required ZIF thickness (typical .012″), polyimide or polyester “stiffener” is attached under the connector circuit to create the proper thickness. The stiffener thickness is adjusted to the construction of the circuit (single sided, double sided, or multi-layered circuit).
Micron Lasers routing processes can adjust laser energy control on the fly as the stack-up thickness and materials change (i.e. transition from 4mil flex to 12mil flex/stiffener). Without proper laser energy control, the thinner circuit areas can be over processed exhibiting charring or discoloration from the higher energy required to rout the thicker flex sections or metal cutting areas.
