Direct manufacturer of custom membrane switches, graphic overlays, silicone keypads, capacitive touch panels and thin-film sensor assemblies with 100% inspection.
Every keypad batch engineered by Dongguan AXRU Electronics Co., Ltd. is evaluated in our internal testing lab to guarantee long-term field reliability.
100% electrical continuity, circuit resistance, short detection and visual cosmetic review before packaging.
Validates bonding peel strength of 3M adhesives and ensures flexible tail exit pull-resistance.
Checks ink adhesion under solvent, alcohol and rub tests to guarantee legends will not fade.
Repeatedly actuates tactile metal domes up to 1,000,000 - 5,000,000 cycles to confirm endurance.
Measures precise actuation force, travel displacement and click ratio curves for uniform tactile feedback.
Tests waterproof sealing and circuit stability under extreme thermal ranges from -40°C to +85°C.
Accelerated UV aging verifies that transparent window materials and white overlays maintain optical clarity.
Dedicated digital plotters and prototyping rigs provide fast sample turnaround in 5 to 7 working days.
Precision stamping achieves ±0.1mm dimensional tolerance for seamless mechanical integration with enclosures.
Dongguan AXRU Electronics Co., Ltd. manufactures tailored HMI interfaces to your mechanical, electrical and environmental requirements.
