TAVO Electronic Information Technology Co., Ltd.
TAVO Electronic Information Technology Co., Ltd. was established in 1990. For over three decades, we have focused on the comprehensive processing, precision engineering, and specialized manufacturing of membrane switches, membrane keypads, and graphic overlays.
Through persistent technical refinement, our core product portfolio has expanded to include high-reliability FPC membrane switches, LED integrated membrane switches, and membrane switches with liner. Our custom human-machine interface (HMI) solutions serve mission-critical applications across industrial automation, medical instrumentation, intelligent household appliances, and electrical apparatus.
Our operations are strictly managed and audited in compliance with the ISO 9001 quality management standard, guaranteeing end-to-end traceability, consistent tactile response, and rigorous electrical performance across every production batch.
International Trust & Critical Infrastructure Projects
Continuous technical expansion and stringent process control have earned our products wide recognition across global markets, backed by nearly a decade of direct OEM/ODM collaboration across the United States, Germany, and European countries.
High-Speed Railway Control
Engineered rugged, high-durability locomotive control panels capable of withstanding intense vibration, mechanical shock, and continuous duty cycles.
Three Gorges Project
Supplied high-reliability control interfaces and precision graphic panels deployed in hydro-electric and national infrastructure monitoring stations.
Aerospace Electronics
Manufactured specialized lightweight, EMI/ESD-shielded switch assemblies adhering to tight aerospace dimensional tolerances and material stability requirements.
State-Run Engineering
Trusted supplier for governmental and municipal equipment programs requiring verified compliance, traceability, and extended product life cycles.
Comprehensive In-House Test Laboratory
Every batch of membrane switches, keypads, and graphic overlays is rigorously validated using dedicated environmental, electrical, and mechanical life testing equipment to prevent field failures.
100% Quality Inspection Computer Circuit Tester
Performs 100% automated inspection of contact resistance, short/open circuit detection, dielectric breakdown, and loop continuity on every finished switch before dispatch.
Mechanical Endurance Button Life Cycle Test Unit
Evaluates tactile snap ratio, rebound force, and switch actuation life through repetitive mechanical cycling up to and exceeding 1,000,000 cycles for metal dome and polydome arrays.
Climate Simulation Humid & Temp Programmable Tester
Exposes interfaces to programmable cyclic thermal and humidity profiles (-40°C to +120°C, 20% to 98% RH) to verify adhesive bonding, silver trace stability, and material integrity.
UV & Sunlight Aging Xenon Lamp Aging Test Chamber
Simulates real-world outdoor spectrums and solar radiation, validating ink colorfastness, polycarbonate overlay yellowing resistance, and long-term graphic film stability.
Corrosion Defense Auto Salt Fog Chamber
Conducts ASTM B117 salt spray testing to confirm corrosion resistance of connectors, metal backers, terminal pins, and ingress-sealed overlay edges in harsh chemical or marine environments.
Clean Assembly Clean Assembly & Packing Line
Final visual inspection, backlight uniformity checking, precision dimensional checks, and anti-static ESD packaging carried out in a temperature-controlled dust-free environment.
CAD/CAM Design & Full In-House Process
By managing everything internally—from drawing design to CAM conversion, film generation, printing, and laser die-cutting—we eliminate third-party delays and maintain total quality supervision.
01. Drawing Design & DFM
Experienced design engineers convert client sketches or CAD files (DWG, DXF, AI, STEP) into optimized DFM manufacturing drawings.
02. CAM & Color Separation
Digital artwork is separated by Pantone code, layer tolerances are calculated, and precision tooling films and printing screens are created.
03. Precision Screen Printing
Conductive silver inks, carbon resistors, and graphic layers are screen-printed under micron-level alignment registration.
04. Embossing & Laser Die-Cutting
Precision tactile rim or pillow key embossing, followed by tight-tolerance CNC laser or steel-rule die-cutting of outlines and windows.
