Thin-Film Metallization
Thin Film Metallization

Thin-Film Metallization

Using vacuum sputtering, evaporation and photolithographic patterning, we deposit precision metal films of 0.05μm ~ 5μm on ceramic, alumina, AlN and similar substrates — meeting next-generation thermal management, optical and RF packaging applications.

  • Multiple alloy systems: Cr / Ni / NiCr / Au / Pt
  • Pattern accuracy ±5μm, film thickness uniformity ≤ 3%
  • Supports large substrates 50.8mm × 50.8mm ~ 200mm × 200mm
  • ROHS / REACH compliant throughout the process

Precision Machining
Precision Machining

Precision Machining

Equipped with laser cutting, ultrasonic dicing and CNC milling, we deliver high-precision cutting, drilling, slotting and contour machining of ceramic substrates and metal housings.

  • Cutting accuracy ±0.02mm
  • Minimum hole diameter 0.1mm
  • Supports hard / brittle materials: 99.6% Al₂O₃ / AlN / sapphire
  • Drawing → sample in 48 hours rapid prototyping

Testing & Validation
Testing & Validation

Testing & Validation

End-to-end testing from incoming inspection to outgoing QA — including electrical performance, reliability and environmental tolerance — with CNAS-accredited reports.

  • Electrical: accuracy, TCR, noise, pulse capability
  • Reliability: thermal cycling, humidity, salt spray, vibration
  • Failure analysis: SEM / EDS / X-Ray full equipment suite
  • CNAS / IEC / MIL-STD reports provided

Process

Five-Step Customization Process

From requirement to delivery, every step has a dedicated engineer assigned — fully transparent and traceable end-to-end.

01
Requirement Discussion

An engineer aligns with you on technical details — power, resistance, package, environmental specs and other key parameters.

02
Solution Design

Based on your application, we provide an initial solution, simulation and cost estimate within 5 business days.

03
Sample Build

After solution sign-off, engineering samples are delivered within 2–4 weeks with a complete test report.

04
Mass Production & Delivery

Production runs with full incoming, in-process and outgoing inspection — delivered to your schedule.

05
Continuous Improvement

Process and quality are continuously refined per usage feedback — supporting long-term cooperation and technology upgrades.
