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.




All A-TECH peelable solder mask pcb are 100% visually inspected. The QC engineers continuously take random samples for detailed computerized dimensional and material compound analysis. The zinc thickness is enough to prevent rust or other hidden dangers
A-TECH enig pcb finish is made from polymers that are made up of many many molecules strung together to form long chains that behave differently. The product features good electrical insulation and strong transmission
A-TECH enig pcb finish has undergone a series of tests such as tensile strength tests, tear tests, H-Drawing tests, compression tests including set up of its stop force. With excellent fatigue resistance, the product is built to last for decades
The production process of A-TECH enig pcb finish involves coagulation, a process that curdles or thickens the polyisoprene into a mass. This process is accomplished by adding an acid. The product features good electrical insulation and strong transmission
Some chemicals and other additives are added to customize the A-TECH peelable solder mask pcb for the intended use, including anhydrous aluminum silicates as reinforcing fillers. It is distinguished by good shock and vibration resistance
The product features low-temperature resistance. Due to its amorphous molecular structure, the low temperature has little effect on its properties. The product can withstand extreme external conditions, such as heavy rain and storm, snow, or thundering
