What are the top FPC manufacturers in the world in 2024? What are the FPC manufacturer's capabilities? You can find answers quickly from this blog.

Top FPC Manufacturers in the World

FPC is a flexible printed circuit. Its other name is flexible PCB. The top 3 FPC manufacturers on the largest scale in the world are:

Avary Holding

Avary Holding Co., Limited - Founded in 1999, it's a listed company in Shenzhen, China. It deals with FPC design, R&D, and manufacturing. Its FPC minimum hole aperture/trace width can be 0.025mm/0.025mm. However, it works only on FPC bulky production for giant OEMs (original equipment manufacturers).

Mektec Corporation

Mektec Corporation - Founded in 1986, it's a Taiwan-Japan joint venture as a subsidiary of Japan's NOK Group. It provides FPC manufacturing, including the FCCL (flexible copper-clad laminate). However, it also only works for long-term and bulky production for giant OEMs.

Sumitomo Electric

Sumitomo Electric Industries, Ltd. - It's a listed company in Japan. It provides bulky FPC manufacturing for smartphones. Like the top FPC manufacturers mentioned above, it only works for giant OEMs.

If you are one of the small & medium-sized OEMs, startups, business makers, and research institutes, it's unlikely for you to meet the requirements of the above top 3 FPC manufacturers.


However, you can work with a one-stop FPC manufacturer, PCBONLINE, that has R&D capabilities and produces FPC without a quantity limit. Founded in 1999, PCBONLINE has one FCCL factory, two large advanced PCB manufacturing bases, one PCB assembly factory, and an R&D team to provide DFM (design for manufacturing) to ensure the success of your FPC project.

For an FPC project, you must want to modify design defects and eliminate potential risks before putting your design into production. By working with PCBONLINE, you can make it.

Advantages of the FPC manufacturer PCBONLINE

PCBONLINE provides free DFM, including BOM (bill of material) check, PCB design, solving potential issues, reducing component procurement costs, etc.

PCBONLINE can do the R&D and take part in your project's early design stage, improving your design, reducing production costs, and preventing possible technical issues in the FAE (Field Application Engineer) stage.

From FPC prototypes to final product box build assembly, PCBONLINE provides one-stop R&D and manufacturing without a quantity limit.

For FPC projects that come to the bulky production stage, PCBONLINE refunds the fees of R&D, final product samples, and FPC assembly functional testing (which means they are free).

Affordable FPC manufacturing and assembly as PCBONLINE produces the FCCL, FPC, and assemblies as a source factory manufacturer.

High-quality FPC manufacturing and assembly certified with ISO 9001:2015, IATF 16949: 2016, RoHS, REACH, UL, and IPC-A-610 Class 2/3.

PCBONLINE offers one-on-one engineering support throughout your FPC project and ensures the design and manufacturing success before FPC production. You can rest assured by working with PCBONLINE for FPC manufacturing and assembly under one roof. To get a quote for your FPC project, please email info@pcbonline.com.

Capabilities of the Top FPC Manufacturer PCBONLINE

An FPC project aims to be used in IoT systems, wearable devices, automotive modules, battery cell packs, smartphones, cameras, computers, industrial controls, medical equipment, aerospace electronics, biological equipment, and military electronics.

FPC projects used for middle and high-end applications require the FPC manufacturer to have powerful capabilities to meet the manufacturing demands. How do you know if an FPC manufacturer can meet your FPC project requirements?
