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
