Product Details

We are a customized High Resistance FR4 Carbon Oil PCB Assembly for Regulator  supplier in Shenzhen. For the production of  fr4 regulator high resistance carbon oil pcb we have a wealth of experience. We adhere to the highest quality standards in both samples and batches.


Special introduction of our manufacturing process:
1. Our company's PCB high resistance carbon PCB 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).

Description:

1. Carbon oil gap: Because carbon oil has good electrical conductivity, so the carbon plate on the finished board should have a certain gap to ensure that no short the circuit, usually require the min 8mil gap on the finished board (HOZ bottom copper), 12mil gap (1- 3OZ bottom copper), if the production of film can increase the gap, then try to increase the gad at the finished board to ensure that no short circuit.

2. Carbon oil minimum tolerance: +/-6 mils

3. Carbon oil window size and copper gap:

consider the tolerance and oil leakage and other factors, carbon oil should bigger 6 mil than copper PAD side(HOZ bottom copper), 8mil (1-3OZ bottom copper), can guarantee not exposed copper.

Carbon oil thickness: silk screen carbon oil thickness: 0.3-1.0mil, tolerance: +/- 0.3mil;


If require carbon oil thickness more than 1.0mil, you need to return the carbon oil twice, The second carbon oil,thickness: 1.0-2.0mil,tolerance: + / – 0.4mil, the second return of carbon oil film should smaller mil than the first silk screen carbon film. So the MI need to write two sets of tools.
