Product Overview:

Carbon Oil PCB from PCBGATE is designed for stable contact and long life.
The carbon layer is printed on the PCB surface to replace gold plating, offering a cost-effective solution for keypads, remote controls, and industrial devices.

Key Selling Points:

· Professional PCB manufacturer with over 15 years experience

· Stable carbon ink with good conductivity

· Cost-effective alternative to gold plating

· Suitable for keypad and contact applications

We are skilled manufacturer in varied Carbon PCB/PCBA with nine years expertise, our cabon PCB is especially used for potentiometer, automotive air con door sensors, automotive wipers, automotive dimmers and resistance sort controllers. we are able to give an inexpensive worth with top quality product.

Main technical parameters:

Resistance Range: 1KΩ to 1MΩ

Resistance tolerance: ±15% (inclusive) or more

Durability: more than 1 million times

Special introduction of manufacturing process

PCB printing insulation paint, silver paint, carbon paint, ink, peelable adhesive need to go through 170°C~230°C, after high-temperature sintering and curing, the film is polymerized, and high-temperature ovens and tunnel furnaces are high-power devices (50KW~60KW).

Production Flow

Engineering Support: DFM (Design for Manufacturing) check before production.

Testing: Flying Probe Test, Fixture Test, Impedance Control Test, Thermal Stress Test.

It is widely used in remote controls, membrane switches, and control panels.

Our factory ensures:

· Stable resistance value
