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:

Gold-Plating finger pcb
Gold Plating Finger PCB

Gold Plating Finger PCB

It’s hard plated gold over plated nickel for edge-connector fingers. . Electroplated gold is thicker and harder making it ideal for edge-connector contacts for PCBs which will be repeatedly plugged in and removed.

Blind-Buried-Via PCB
Blind-Buried-Via PCB

Blind-Buried-Via PCB

Blind and buried vias are used to connect between layers of a PCB where space is at a premium. A blind via connects an outer layer to one or more inner layers but does not go through the entire board. A buried via connects two or more inner layers but does not go through to an outer layer.

18 Layers HDI PCB
HDI PCB

HDI PCB

HDI boards, one of the fastest growing technologies in PCBs. HDI Boards contain blind and/or buried vias and often contain microvias . They have a higher circuitry density than traditional circuit boards.

Flex-rigid PCB

Flex-rigid PCB

The typical flex-rigid PCB circuit includes two or more conductive layers that comprise either flexible or rigid insulation material between each one ,the outer layers may have either exposed pads or covers.

Castellated Hole PCB
Castellated Hole PCB

Castellated Hole PCB

Castellated features are vias or thru holes that are cut through to create a partial or half hole for the purpose of creating an opening into the side of the hole barrel. These partial features are used for the purpose of mounting a PCB to another PCB by means of solder, or insertion of specially design edge connectors.

Rogers+FR4 Mix Stack Up
Rogers + FR4 Mix Stack Up PCB

Rogers + FR4 Mix Stack Up PCB

Rogers + fr4 mix compression boards.The hybrids use materials with very different dielectric constants that are used for enhanced electrical performance. In the case of some couplers or filters, it may be advantageous to use laminates with different dielectric constant values.
