M2PCB details high-precision flexible PCB process and production capacity

M2PCB outlined its flexible printed circuit manufacturing process in Shenzhen, highlighting fine-line routing, bend-resistant substrate construction, and quality testing for advanced electronics. The company also detailed certifications, monthly output, and a red light therapy belt application that reached 500,000 units for a U.S. customer.

Why it matters: - M2PCB is targeting flexible electronics that need tighter routing, repeated bending, and consistent electrical performance. - The company’s manufacturing specs and certifications matter for buyers in medical, automotive, and consumer electronics markets. - The stated capacity and low minimum order quantity position M2PCB for both prototyping and high-volume production.

What happened: - M2PCB, a Shenzhen-based group company focused on Flexible Printed Circuit and PCBA production, described its CoreTechnologyArchitecture for flexible PCB manufacturing. - The company said its factory spans 8,000 square meters, employs 200 people, and produces 360,000 square meters annually. - M2PCB said it manufactures 1- to 14-layer flexible PCBs and delivers about 800 varieties per month. - The company said its monthly production capacity is 40,000 square meters. - M2PCB said typical lead times range from 3 to 20 days, depending on order complexity. - The minimum order quantity is 1 unit. - The company exports to Europe, the United States, South America, and Australia, with exports accounting for 70% of output.

The details: - M2PCB’s flexible LED PCB achieves a minimum line width of 0.05 mm and minimum spacing of 3/3 mil, or 0.076 mm by 0.076 mm. - The maximum panel width is 240 mm. - The board uses a polyimide, or PI, substrate for thermal stability and flex endurance. - Automated exposure and etching are used to keep trace geometry consistent across production runs. - The fabrication process includes laser drilling, hot pressing, and PI reinforcement to improve bend resistance and layer adhesion. - M2PCB said the thin-core PI material and controlled lamination parameters help the product withstand repeated bending cycles without conductor fatigue. - The company’s PCBA services include Turnkey BOM options, program burning, X-ray testing, fly-probe testing, automated optical inspection, and 100% electrical testing. - All materials meet RoHS requirements. - M2PCB said its quality control system follows ISO guidelines. - The flexible LED PCB is certified under UL standard E530809 for medical aesthetics, automotive, and electronic products. - The UL certification covers compliance with UL6950-1, UL60065, and UL62368-1. - The product also meets IATF 16949:2016, under certificate T184452 issued by NQA. - The company showed laser direct imaging and drilling equipment in its production line. - The company also showed a visual inspection station for final quality assurance.

Between the lines: - M2PCB is signaling that its value proposition is not just flexible PCB output, but process control across routing, lamination, and inspection. - The combination of UL and IATF references suggests the company is aiming at regulated and safety-sensitive applications. - The red light therapy belt example shows how the same flexible PCB platform can be adapted for wearable and body-conforming products. - M2PCB said one ODM project delivered 500,000 units for a U.S. customer over two years. - The belt design uses PI-based flexible PCB strips that conform to the body while maintaining reliability under repeated flexing. - The application is used to deliver photobiomodulation for pain relief in the waist area.

What's next: - M2PCB is positioned to pursue additional custom flexible PCB and PCBA orders across prototyping and volume production. - The company’s mix of low MOQ, short lead times, and export reach suggests continued focus on international demand. - Buyers seeking flexible circuits for compact or bend-intensive products may look at M2PCB’s routing and substrate process as a differentiator.

The bottom line: - M2PCB is pitching a manufacturing platform built for dense, durable flexible circuits, backed by testing, certifications, and a broad production range.
