The detailed process of fabricating Flexible PCBs involve the following steps:
Shearing
This step involves cutting the material as per different sizes, designs and layout specifications.
Drilling
Depending on the exact design, this involves drilling different holes such as alignmnet holes, testing vias, component holes and more.
Through-Hole Plating
Post drilling the next step involves through-hole copper plating to establish connection between layers.
Dry film lamination
Pre-treated boards are passed through hot roller to laminate the dry film on it.
Exposure
The designated circuit pattern image is transferred to the dry film to cretae an exposure area.
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.
Etching
This process involves initiating a chemical reaction on the non-exposure area and ensuring the protected area remains unchanged.
Stripping
At this stage, the dry film covering the circuit pattern is removed.
AOI (Automated Optical Inspection)
A robust process, this checks the quality of the circuit boards.
Coverlay pre-lamination
An insulating layer called the coverlay is introduced to protect the circuit boards.
Hot Press
Next, the board is passed through a hot press to ensure adhesion.
Metal Coating
The bonding area is coated with metal, often gold or nickel.
Screen Printing
Silk screening is applied to print information such as logos.
Testing
Robust electrical and functional testing ensures efficacy of the circuit boards.

Some of the other advantages that Flex PCBs offer include:
Reduced assembly time and costs
Not only do they require less manual labor, they also take away the high cost of routing, wrapping and soldering wires. The fact that they also lend themselves to reduced errors in PCB assembly, is an added perk.
Freedom of Design
As opposed to rigid boards that offer restrictions, flex boards offer endless design options. In fact, at Mermar Electronics we take great pride in designing highly complex boards that can stand the test of time in harsh environments.
Ease of Installation
Once again as opposed to rigid boards, flex PCBs lend themselves to ease of installation. With flex boards you do not have to contend with space or weight issues.
Ideal for high-density Applications
With miniaturization being the need of the hour, the demand for flex PCBs has increased as it frees a lot of space and can fit in easily.
Improved heat dissipation
With the compact design of PCBs, it allows a shorter thermal path and hence lends itself to improved heat dissipation.
Maximum Reliability
With fewer interconnections, Flex PCBs offer improved reliability.
Reduced Weight
Flex PCBs are being extremely thin; they allow not only for streamlined designs but also reduced package size and weight.

Application of Flexible PCB Fabrication
Flexible circuit boards find both static as well as dynamic application. While a static application involves designing circuits with a small amount of flex, a dynamic application involves the circuit being flexed repeatedly. Such applications are designed with RA Copper.
Some of the industries that Flexible Circuit Boards find extensive application in, include:
- Electronics
- Manufacturing
- Automotive
- Medical
- Aerospace
- Military and Defense
- Telecommunications
- Transportation
