High Resistance Carbon Oil PCB – 1KΩ to 1MΩ Customizable Range

Product Overview:

Carbon Oil PCB from PCBGATE is designed for stable contact and long life. Single sided high resistance carbon pcb for windscreen wiper. 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. Can meet the special requirements of the cup shape hole, cone shape hole, mirror surface aluminum base, and the 3oz 4oz thicker copper circuit board etc.

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

Applications for Carbon Ink PCBs

Other uses for carbon ink are to create surface resistors and slider switches for potentiometers. These require even more skill to screen since the definition of the feature directly impacts the performance of the board.

Carbon inks and adhesives play an increasing role in applications including printed resistors, polymer thick film circuitry, membrane switches, electrical attachments, heaters, and static elimination. Carbon inks to obtain a range of electrical conductivity values by blending them with silver inks and adjust conductivity to a specific level. Creative Materials can also blend carbon inks with silver inks to reduce cost for some applications.

Carbon inks are lubricious, providing low friction and excellent thermal stability. They are also chemically inert, with low reactivity to solvents and other chemicals. Carbon inks can be applied by screen-printing, dipping, and syringe dispensing and feature excellent adhesion to Kapton, Mylar, glass and a variety of other substrates. Unlike conventional conductive materials, carbon inks are very resistant to abrasion, scratching, flexing and creasing.

Carbon inks are environmentally friendly, while offering the same characteristics of high printability and varying electrical conductivity as our solvent-based carbon inks.

Production Process:

PCB Manufacturing Process:

Engineering Review → Material Preparation → Circuit Pattern → Copper Bonding → Etching → Solder Mask → Surface Finish → Testing → Packing

Special introduction of manufacturing process
1. Our company's PCB high resistance carbon printing materials: carbon paint, silver paint, insulating paint, ink, peelable plastic, etc are imported materials with expensive price, and material cost is the most important cost.

2.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).

According to the process of copper surface treatment of the circuit board
1, FR-1: Single Side Gold Plating and Sinking Gold Plates
2, CEM-1: Single Side Gold Plating and Sinking Gold Plates
3, CEM-3: Single Side Gold Plating and Sinking Gold Plates
4, FR-4: single-sided, double-sided and multi-layer gold-plated, Sinking Gold Plates
