Flexible PCB Manufacturer in China

Advantages of HXD as a PCB Fabricator

We not only produce Flexible PCBs, but we are also committed to solving the physical limits of Flexible PCBs through advanced processes.

Materials
HXD uses high quality materials such as Dupont and Shengyi in Flexible PCB manufacturing, and also offers PCB stiffener including PI, FR4 and stainless steel. For dynamic bending requirements, we can also offer a highly flexible RA Copper solution that can support millions of 180° dynamic cyclic bends without cracking.

Equipment
HXD has a complete range of Flexible PCB production equipment, including process equipment for copper lamination (FCCL), etching, laser and mechanical drilling, and surface treatment. High-precision UV laser technology enables blind vias as small as 0.075mm (3mil), providing more routing space for miniaturised devices.

Customisable
HXD offers custom Flexible PCBs, including 1 to 10-layer flexible boards, single-sided flexible boards, double-sided flexible boards, Rigid-Flex PCBs, and transparent flexible boards.

What Is a Flexible PCB (FPC)?

Flexible PCB (Flexible Printed Circuit), also called FPC, is a type of printed circuit board made from flexible substrates (such as PI). It does not have the mechanical rigidity of a normal rigid PCB. Flexible PCBs can bend or fold back and forth freely without harming the inner electronic circuitry. They can withstand high-intensity mechanical movement and keep the signal going. Flexible PCB has become the key technology that makes today’s electronic products light, thin, short, and small.

Flexible pcb Stack-Up

In Flexible PCB design, the design of the Stack-Up directly affects the impedance control, flexibility, and overall thickness of the board. Below are a few typical stack-up solutions. For customisation, please contact us and we will manufacture to your specifications.

Why Choose Flex PCB(FPC)?

The advantage of Flexible PCB is not only the softness, but also the overall optimization of the system.

Optimum use of space: Flexible boards can be folded and curled in 3 dimensions to fill the product shell. It is easy to bend to avoid internal obstacles.

Reduced weight significantly: Flexible pcb can reduce the weight of the circuit by 70% – 90% compared to rigid boards. It is very suitable for aerospace, drones and wearable devices to help achieve long endurance.

Superior Durability:With RA copper, Flexible PCB can survive millions of dynamic bends without cracking or breaking.

Reliable performance: Flexible PCB can reduce the use of connectors, which greatly reduces the risk of poor contact due to vibration.
