 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).
