Carbon ink PCB, is the circuit board with carbon ink applied onto the copper pad. The carbon will be a conductor to connect two traces on PCB board, and a resistor between the traces or traces and components. The key factor in carbon ink PCB production is to control the printing, baking and resistance control. The carbon ink can be printed onto flexible circuit, rigid-flex board and rigid PCB, such as polyimide, polyester, FR-4, FR-5 and PTFE laminates. Carbon ink can offer resolutions as fine as 100μm trace width and spacing, and it is always applied for the printed circuit boards, including RF shielding, keypad, remote control, automotive vehicles, industrial engine control, welding equipment and etc.
Carbon Ink PCB are typically used to create a protective contact surface for switches, which are far more cost effective than typical alternative: hard electroplated gold.
We offer one-stop Carbon ink PCB solutions. We are Carbon ink PCB manufacturer in China.
Yes, laser trimming is available, and the linearity variation tolerance can up to ±0.02%.
The distance between the carbon tracks more than 0.4mm.
Yes, laser corrected requested if linearity variation tolerance less then 2%.
It is recommended that the contact force between carbon wiper and carbon ink is less than 20 mg. For details, please consult the metal carbon wiper supplier for specific parameters. Wiper quality based on bending strength and wearing strength.
Yes, it’s available. But the thickness of carbon ink cannot be too thick. As thinner as possible for example less than 18μm.
