Growth and proliferation for flex circuits and flexible printed circuit boards continue exponentially. Flexible printed circuits, also known as flex circuits, are sometimes regarded as a printed circuit board (PCB) that can bend. Flexible circuits are members of the electronic and interconnection family. They are mainly composed of CU (copper foil), acrylic, epoxy resin thermal-setting glue and PI  to protect the conductor circuits. The technology has been used for interconnecting electronic devices since the 1950s in one form or another. It is now one of the most important interconnection technologies in use for the manufacture of many of today's most advanced electronic products.

In the article, you will read something about the characteristics of the flexible PCB. According to it, you will know more about the flexible PCB.

Here are some characteristics of the flexible PCB:

1. The size of the flexible PCB is comparatively small.

2. The flexible PCB is easier to be controlled by engineers.

3. The flexible PCB is durable and reliable.

1. The size of the flexible PCB is comparatively small.


The flexible PCB can be used in a way of rolling up or being folded up. The conductor cross-section of the flexible PCB is thin and flat, so that the wire size can be reduced. Compared to the hard PCB, the flexible PCB has a 60% reduction on the PCB area. Also, in the same volume, the weight of a flexible PCB can be reduced by about 70% compared with a wire and cable at the same current carrying capacity. Compared with a rigid PCB, the weight can be reduced by about 90%.

2. The flexible PCB is easier to be controlled by engineers.

According to application requirements, engineers can control capacitance, inductance, characteristic impedance, delay and attenuation when designing the flexible PCB. They can be produced to have the functions of a transmission line. Technologically, these parameters are related to wire width, thickness, spacing, insulation layer thickness, dielectric constant, loss tangent, etc., so it is difficult for engineers to complete this process when using wire cables. What’s more, the flexible PCB can be manufactured with different base materials according to different usage requirements.

3. The flexible PCB is durable and reliable.

Flexible printed circuit boards can withstand thousands of times of use without damage. When installing the flexible PCB, factories will eliminate errors. As long as the processing drawings are proofread and passed, all the winding circuits produced later will be the same. There will be no wrong connection when installing the cable. It’s convenient to check the PCB in the future. To customers, choosing a flexible PCB is more reliable.

Our company, Boyunfa, has a long history of producing and designing the flexible PCB. we have many excellent cooperative factories,they have many QC auditors with rich experience who use advanced testing equipment such as AOI, BGA X-ray and PCB E-test to ensure all our products comply with I S O, U L certifications. We purchase superior raw materials and components from the authorized dealer, and we have established a quality control department to strictly monitor each production detail.

Thanks for your trust! We hope to have a cooperation with you!
