Capacitive Touch Sensor

Capacitive Membrane Switch with PET substrate, the thickness can be as thin as 25 μm, with printing thickness uniformity controlled within ±1 μm. It enables precise fitting into the internal space of equipment, helping products achieve ultra-thinness and simplified structure while maintaining stable performance.

Our printing process achieves ultra-fine printing with a line width down to 0.1 mm. Complex circuits including straight lines, horizontal lines and arc patterns all feature sharp edges, free of ink overflow and burrs. The flexible printed circuit remain clear and uniform even under 100× magnification, ensuring stable and reliable signal transmission, and providing solid technical support for high-precision, high-density device interaction design.

The line width of flexible printed circuit can be controlled at 0.1±0.02 mm(Industry Average: 0.3 mm), enabling ultra-fine circuit layout. This not only effectively improves the stability and response speed of signal transmission, but also allows more functional contacts to be integrated in a limited space, providing core support for high-density design and precise control experience.

We achieve a registration accuracy of ±0.05 mm for 7-layer printing. By precisely controlling the shrinkage rate and alignment deviation of the substrate, we can stably reach a registration accuracy of ±0.05 mm even on ultra-thin 25 μm PET material.
