Flexible Printed Circuits & Circuitries- Dual Access


Dual Access Flexible Printed Circuits has the same construction as single-sided flexible printed circuit; however, pre-routed openings are made in the cover film allowing access to both sides of the copper layer.


Application of dual access flex printed circuits & flex PCBs:


Vibration Motor for Mobile Phone
LCD Module for Mobile Phone
