Enig Polyimide Flexible PCB Board Printed Circuit Board

-Definition

Flexible PCB – Flexible Printed Circuit, referred to as FPC.

A flexible printed circuit can be defined as an outline of conductive traces bonded on a flexible substrate. It is made into conductor circuit patterns using light pattern expose transfer and etching processes on the surface of a flexible substrate.

-Characteristics

Flex circuits widely used in mobile phones, cameras and smart wearable’s.

polyimide pcb can better fit wiring capability in spaces than the traditional rigid boards.Flexible circuit boards also have better resistance to high temperatures, shock and vibrations. polyimide copper flexible pcb has good performance with design challenges such as: unavoidable crossovers, specific impedance requirements, elimination of cross talk, additional shielding and high component density.

-Classify

• Single-sided flex PCB
• Single-sided flex with dual accesss
• Double-sided flex PCB
• Multi-layer flex PCB

Flexible PCB Manufacturing Process

-Double-side Flex-PCB:

Cutting → Drilling → PTH → Electroless Plating → Pretreating → Dry Film Lamination → Position → Exposure → Develop → Pattern Plating → Remove Dry Film → Pretreating → Dry Film Lamination → Position and Exposure → Develop → Etching → Remove Dry Film → Surface Finish → Cover lay Lamination → Lamination → Curing → Immersion Gold → Silkscreen → V-cutting/scoring → Electrical Test → Punching → FQC → Packaging → Shipment

-Single-side Flex-PCB:

Cutting → Drilling → Dry Film Lamination → Position and Exposure → Develop → Etching → Remove Dry Film → Surface Finish → Coverlay Lamination →Lamination → Curing → Surface Finish → Immersion Gold → Silkscreen → V-cutting/scoring → Electrical Test → Punching → FQC → Packaging → Shipment
