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.
1) Carbon ink PCB with high quality which compliance after RoHS and REACH.
2) Laser corrected is available. The Linearity error can up to ±0.02%.
3) Full experience in exporting Carbon ink PCB to European and American market.
4) The conductive ink we normally use from Asahi Chemical Research Laboratory Co., Ltd.
5) Capable of producing Carbon ink PCB up to 2000mm material in total for the longest length.
Conductive ink from Asahi Chemical Research Laboratory Co., Ltd.
Yes, laser trimming is available, and the linearity variation tolerance can up to ±0.02%.
The min space is 0.3mm, ideal space is 0.5mm
The distance between the carbon tracks more than 0.4mm.
At least or more than 0.15mm (normally the mini solder mask width can be accepted is 0.15mm and tolerance is ±0.1mm).
Yes, laser corrected requested if linearity variation tolerance less then 2%.
Normally if each item total amount over 2,000$ then can be free.
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.
Thickest carbon ink we can do is 25-60μm. We need double printing of carbon ink if the thickness over 25μm.
Yes, it’s available. But the thickness of carbon ink cannot be too thick. As thinner as possible for example less than 18μm.
