FR4 PCB Capability
With 15+ years’ experience in PCB fabrication, we have handled hundreds of thousands of PCB projects, and covered almost all kinds of substrate materials including FR4, Aluminum, (PTFE)Rogers, etc. This page only touches standard FR4 based PCB. For PCBs with special technical substrate, please refer to corresponding web pages for information.
We can manufacture up to 10 million pieces high quality PCBs with very competitive prices. To endow your project with expected function and more possibilities, we offer advanced features for FR4 PCB services. Comprehensive capabilities can be found in the following table:
