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).
