What is Flex PCB?

Flexible PCBs (Flexible Printed Circuit Boards) are electronic circuits that are manufactured on a flexible substrate material, typically made of polyimide or polyester. These flexible substrates allow the PCBs to be bent, twisted, or folded into different shapes to fit into tight spaces or to conform to irregular surfaces.

Flexible PCBs are commonly used in applications where space is at a premium, such as in medical devices, aerospace, and consumer electronics. They offer numerous advantages over rigid PCBs, including reduced weight, increased reliability, and improved signal integrity. Flexible PCBs can also reduce the number of interconnects required, which can result in lower assembly costs and improved performance.

Flex PCB Assembly

Flex PCB assembly refers to the process of attaching electronic components to flexible printed circuit boards. Flex PCBs are ideal for applications where space is limited or where a board needs to be bent or twisted. The assembly process involves placing and soldering components onto the flexible board, followed by testing to ensure that the circuit functions correctly. Our service provides expert flex PCB assembly for a wide range of applications.

Flexible PCB Manufacturing Process

The detailed process of fabricating Flexible PCBs involves the following steps:

1. Shearing

This step involves cutting the material as per different sizes, designs and layout specifications.

2. Drilling

Depending on the exact design, this involves drilling different holes such as alignment holes, testing vias, component holes and more.

3. Through-Hole Plating

Post drilling the next step involves through-hole copper plating to establish connection between layers.

4. Dry Film Lamination

Pre-treated boards are passed through hot roller to laminate the dry film on it.

5. Exposure

The designated circuit pattern image is transferred to the dry film to create an exposure area.

6. Development

By casting UV light on the film, the dry film on the exposure area is hardened while the one on the non-exposure area can be removed.

7. Etching

This process involves initiating a chemical reaction on the non-exposure area and ensuring the protected area remains unchanged.

8. Stripping

At this stage, the dry film covering the circuit pattern is removed.

9. AOI (Autom
