FPC Prototyping
What does Flex PCB prototyping mean? Why Flexible PCB prototyping?
What is the function of Flex Circuits prototyping? Flex PCB
prototyping refers to the designer has designed the drawings, but
to ensure no mistakes and perfect PCB performance, the test
products, i.e. samples, will be made before mass production.
Flexible PCB prototyping first needs to give the specific PCB data
for prototyping to the partner manufacturers. Take the PCB
manufacturer as an example. First of all, we need to give the
specific data of PCB prototyping to the staff, who will quote the
customers and the delivery cycle of products according to the
specific data, process requirements and proofing quantity. If both
parties think there is no problem, after both parties sign the
cooperation contract, the staff will arrange the order and follow
up on the production progress.
Flex Circuit Board Cutting
Customized size cutting can save costs:
First, the first step is material cutting. It is necessary to cut
the board according to the data and design requirements provided by
the customer, and cut the substrate material to the required size.
After cutting, the substrate needs to be pretreated to remove the
surface pollutants of copper film and improve the surface
roughness, which is conducive to the subsequent film pressing
process.
Flexible PCB Structure Layer formation
Lamination-Exposure Development-PTH Removal:
PCB, the inner layer shall be pressed first, and the copper surface
of the finished substrate shall be pasted with an anti-corrosion
dry film through hot pressing. Then, after exposure and
development, the image on the original negative film is transferred
to the photosensitive base plate through the action of the light
source, and the dry film without chemical reaction is washed off
with alkali solution, leaving the dry film with chemical reaction
as the anti-corrosion protective layer during corrosion. The
exposed copper after development is corroded by the drug solution
to form the required inner line pattern.

Rigid-flex PCB introduction:
A rigid-flex PCB (printed circuit board) is a type of circuit board
that combines both rigid and flexible materials in its
construction. It offers the advantages of both rigid and flexible
PCBs, making it suitable for applications where space constraints,
complex geometries, and reliable interconnections are important.
In a rigid-flex PCB, the board consists of multiple layers of rigid
materials, typically FR4, and flexible materials, such as
polyimide. The rigid portions provide structural support and
accommodate components, while the flexible areas allow the board to
bend or fold as needed.
Rigid-flex PCBs are commonly used in electronic devices that
require a compact form factor, such as smartphones, tablets,
wearables, and aerospace applications. They offer several benefits
over traditional rigid PCBs, including:
Size reduction: Rigid-flex PCBs can eliminate the need for
connectors and cables, enabling a significant reduction in space
requirements.
Increased reliability: Rigid-flex PCBs have fewer interconnects and
solder joints compared to traditional PCBs, reducing the potential
points of failure. They also offer better resistance to vibration
and thermal stress.
Improved signal integrity: The combination of rigid and flexible
materials allows for optimized signal routing, reducing signal
loss, and improving overall signal integrity.
Enhanced design flexibility: Rigid-flex PCBs can be designed to fit
complex and irregular shapes, conforming to the available space in
a device. This flexibility enables innovative product designs.
