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.



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

It 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. it has good performance with design challenges such as: unavoidable crossovers, specific impedance requirements, elimination of cross talk, additional shielding and high component density.



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




ABIS 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

How ABIS Dealing With Flexible PCB Issues?

The first thing we ensure is the right equipment to produce your board. Next, the staff experienced enough to handle the challenge of manufacturing flexible boards.

  • Opening a solder mask or overlay enough-different steps of the process might change how a flexible board looks. Etching and plating can adjust the shape of the PCB, which is why you should ensure that overlay openings are of suitable width.
  • Choose the materials carefully, also considering other things, such as size, weight, and reliability of the board.
  • Control appropriate proximity of solder joints and bending point – the solder joint should be at the required distance from the bending location. If you put them too close, delamination or broken solder pad may occur.
  • Control Solder pad spacing – ABIS ensuring there is enough space between the pads and the conductive traces adjacent to them, so that avoiding lamination loss.




Quality Guarantees

  • Following your instructions and desires to the smallest detail.
  • Choose the best material for your application and budget.
  • Assemble and deliver the board within the specified time frame.
  • The pass rate of incoming material above 99.9%, the number of mass rejection rates below 0.01%.
  • One-year warranty. if any quality problems, not caused by improper use or man-made, ABIS will replace it one by one.
