MORE PCB LTD Offer High Quality FR4 PCB Fabrication Services.
Our FR4 PCB productions are trusted by thousands of PCB designs & engineering companies.
We have enough advantages to manufacture variety of PCB from single to double sided, multi-layer Printed Circuit Boards and the latest materials and processes.
Also have dedicated branches specializing in different types of Printed Circuit Boards to optimize for cost and leadtime.
MORE PCB LTD offer prototype PCB services, quick lead-time PCB runs and no minimum order quantity.
We focus to deliver quality PCB’s at a low cost – more so than from any other PCB manufacturer.
In addition, our PCB designers look over every design for potential mistakes, this service can’t be found at most PCB fabrication houses.
Also, we follow very strict PCB manufacturing workflow to ensure the high quality delivery.
Our FR4 PCB Comprehensive Capability
With 10+ 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:
