From rapid NPI turnarounds to high-volume Tier-1 scalable manufacturing, explore our field-proven human-machine interface components designed for medical electronics, cleanroom equipment, and industrial automation.
From medical device hubs in North San Jose and Sunnyvale to robotics corridors in Fremont and Santa Clara, our engineering matches the stringent environmental, electrical, and tactile requirements of California's top hardware pioneers.
San Jose and Silicon Valley MedTech leaders require completely sealed, antimicrobial front panels capable of withstanding daily sterilization using hospital-grade chemical disinfectants (bleach, IPA, glutaraldehyde). We manufacture continuous-surface IP67/IP68 tactile membrane switches with flush embossed keys that eliminate bioburden retention crevices.
Serving the massive semiconductor tool corridor from San Jose to Milpitas, our control panels are engineered for zero outgassing in vacuum and cleanroom chambers (ISO Class 5/6). Equipped with static dissipative coatings, ITO shielding, and grounded copper mesh, these panels prevent ESD events that jeopardize sub-nanometer wafer processing nodes.
Silicon Valley's electric vehicle startups and EVSE infrastructure developers deploy equipment into severe outdoor environments. We integrate UV-stabilized Autotex XE polyester films that resist yellowing and embrittlement under intense California sunlight, paired with wide-temperature (-40°C to +85°C) silicone and 3M 467MP/468MP laminates.
Deployed throughout Bay Area logistics automation platforms and commercial robotics, our metal snap dome arrays provide unmistakable tactile confirmation for operators wearing heavy work gloves. With trip forces tuned up to 450g and actuation lifespans surpassing 1,000,000 cycles, our keyboards deliver failsafe operation on rough vibration terrains.
Engineered for portable spectrum analyzers, field calibrators, and smart agricultural sensors tested in Silicon Valley R&D centers. We combine ultra-thin Flexible Printed Circuits (FPC) with gold-plated SUS301 round domes to minimize enclosure depth while preserving high electrical conductivity under continuous mechanical flexing.
Contract manufacturers in San Jose supplying Tier-1 aerospace prime contractors demand absolute adherence to Mil-spec requirements. Our high-reliability panels utilize nickel-plated snap domes, RFI shielding meshes, and light guide film (LGF) backlighting that supports night-vision goggle (NVG) compatibility with zero electromagnetic emissions.
As Silicon Valley companies push the boundaries of embedded computing and industrial design, touch interface technologies are undergoing profound architecture shifts.
Silicon Valley hardware architects are increasingly transitioning from purely visual touchscreens to hybrid interfaces. By integrating capacitive touch sensor films beneath tactile SUS301 stainless steel domes, engineers eliminate phantom touches in high-vibration aerospace or automotive scenarios while maintaining modern sleek aesthetics.
Post-pandemic medical device standards in Northern California necessitate complete enclosure hermeticity. Liquid-proof perimeter gasket adhesives combined with die-cut vent channels allow internal air displacement during rapid button depression without drawing in ambient moisture or aggressive hospital disinfectants.
Instead of bulky discrete through-hole LEDs, San Jose portable device designs require thin Light Guide Films (0.125mm to 0.25mm). By side-firing ultra-compact SMD micro-LEDs through patterned optical micro-prisms, our panels achieve uniform key illumination with less than 20% of conventional power consumption.
Silicon Valley hardware teams operate on accelerated product introduction cycles (NPI). San Jose design centers demand DFM (Design for Manufacturability) iteration within 24 hours, rapid stereolithography and screen prototypes within 5 business days, and seamless migration into high-capacity ISO 9001 production lines.
A high-performance membrane switch or metal dome array is not merely a piece of printed plastic; it is a high-precision multi-layer electromechanical composite. Each sub-millimeter layer must be calibrated for mechanical flexural endurance, thermal expansion coefficient parity, and dialectric isolation.
At Dongguan Cevra Electronic Technology Co., Ltd., our engineering stack-up begins with premium MacDermid Autotex textured polyester or Sabic Lexan polycarbonate. Circuits are printed using high-purity micro-silver paste (sheet resistance <0.05 Ω/sq/mil) combined with carbon overcoat protection against silver migration.
Our stainless steel snap domes are cold-formed from Japanese fine-grain SUS301 strip steel, ensuring precise tactile feedback, crisp snap ratios (>45%), and guaranteed actuation exceeding 1,000,000 cycles under ASTM F1578 testing standards.

Established in March 2009, Dongguan Cevra Electronic Technology Co., Ltd. operates a 2,600m² purpose-built cleanroom production facility in Dongguan, Guangdong, China. We combine advanced Japanese fabrication equipment with rigorous Western quality auditing.
Our facility runs under an internationally accredited ISO 9001 management system. Every production lot adheres to strict Statistical Process Control (SPC), incoming raw material quarantine, and traceable serial batch numbering for complete audit transparency.
Unlike trading companies and broker desks, Cevra is an authenticated physical manufacturer. Our engineering offices, cleanrooms, and testing facilities have undergone stringent onsite inspection and verification by SGS Group, the world's benchmark inspection authority.
Every custom switch undergoes rigorous testing in our on-site lab: automated CCD optical inspection, 100% electrical continuity and open/short testing, dome force-displacement curve analysis, high/low temperature soaking (-40°C to 105°C), and holding tack testers.
We deploy high-speed automatic CCD camera drilling and high-accuracy laser die-cutting machines. This guarantees overlay window alignment within ±0.05mm tolerances, preventing cosmetic light leaks around OLED, TFT, and 7-segment LED display windows.
All sensitive membrane switch lamination, optical display window bonding, and metal dome array tape assembly take place within positive-pressure, ESD-controlled cleanrooms. This prevents airborne particulate entrapment and surface Newton rings.
Our bilingual senior electrical and mechanical engineers review customer CAD, DXF, Gerber, and AI artwork with overlapping California business hours. San Jose clients receive comprehensive DFM reviews, stack-up recommendations, and quotes within 24 hours.
