Company Advantages
1. All specifications of our pcb surface finish are available.
2. A-TECH has been highly recommended not only the good quality of pcb surface finish but also the professional service. It has low water absorptivity in the damp environment
3. This product can maintain its clean appearance. Its antistatic fabrics help keep particles away from it and make it not easily get dusty. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
4. This product has wear comfort. Elements affecting comfort which involving human physiology and the role of clothing are well-arranged its design. It is offered with low dielectric loss
5. This product does not easily get discolored or dingy. Its fabric materials will last for a long time and stay vibrant and maintain a fresh look. It can be printed with numbers, names, data codes, logos, or other specific information


Carbon Ink is typically used to create a protective contact surface for switches, sometimes few copper elements or patterns of the PCB board are used for keyboard contacts, LCD contacts and jumpers etc, to do this it’s usable to print some conductive/resistive carbon ink over those copper part, which normally are SMD pads or fingers or other typical contact patterns.

Carbon Ink printing process is screen printing like silk screen process, the carbon ink is printed in the specified location of the PCB, after oven cured and tested, formed a carbon film which with certain resistance to instead of the original resistance components. The difference is that silkscreen is only played a welding role but carbon ink has conductive performance.

The typical thickness of carbon ink is 10-50um, because the carbon ink has good electrical conductivity, so the carbon printed on the finished PCB should have a certain gap to ensure that no short circuits, usually require the min 8mil gap for Hoz copper and min 12mil gap for 1-3oz copper, and the minimum carbon line width is 12mil.

A-TECH is a capable PCB manufacturer to offer Carbon ink process, we require the data files to clearly indicate on which side of the PCB carbon is to be applied and the carbon areas must be properly indicated on specific layers with proper file naming.




Company Features
