Zero Insertion Force (ZIF) Connectors
Mating with Zero Insertion Force (ZIF) connectors is an increasingly popular
termination for flexible printed circuits.
Use of a ZIF connector eliminates the need for a mating connector. The flex end
“mates” into the connector, usually located on a rigid board.
Several issues should be addressed with a ZIF termination:
- With a ZIF connector, registration between the cutline of the circuit and the center of the conductors must be closely controlled. All Flex has developed a robust manufacturing process for optimum control of this feature. The process capability profile can be viewed in the attached pdf file. Click here for ZIF Graph
- Material thickness in ZIF mating areas is critical. .012” is common.
This can easily be accomplished by the addition of a polyimide stiffener in the mating area.
- When adding a polyimide stiffener, coverlay and stiffener points should overlap a minimum of .030” (.76mm) to avoid stress points.
