Precision Machining & Specialized Process Combinations
CMI specializes in high-precision machining and specialized process combinations, including multi-axis CNC, precision stamping with in-die operations, EDM/wire cutting for hard materials, and selective surface finishing for enhanced functionality.
- 5-axis CNC & automatic lathes – Achieves tolerances as precise as ±0.005mm.
- Precision stamping – Produces connector terminals & shielding cans, with in-die tapping and riveting.
- EDM & wire cutting – Creates micro-holes/complex slots in hard materials like Invar and Kovar.
- Surface finishing – Offers selective plating (gold/silver/tin-nickel), passivation, anodizing, and EMI shielding coatings.
Telecom & Electronics-Specific Assembly Capabilities
Specialized telecom & electronics assembly capabilities covering micro-assembly, electrical performance testing, and sealing validation for optical modules, RF components, and outdoor base station equipment.
-
Micro-assembly: automated dispensing, laser welding, precision pressing for optical/RF housings
-
Electrical testing: contact resistance, dielectric withstand, VNA (S-parameter validation)
-
Sealing verification: helium mass spectrometry leak detection
-
Environmental protection: meets IP67/IP68 for outdoor base station equipment
Quality Traceability & Risk Control
Rigorous quality assurance is enforced through statistical process control, full traceability via laser-marked 2D codes, and 100% inspection of critical dimensions.
- SPC & CPK: SPC reports per batch; CPK ≥ 1.33 required.
- Full traceability: Laser-marked 2D codes link to raw material lot, machine, operator, and inspection data.
- 100% critical dimension inspection: Using CCD optical sorting or CMM.
- Risk control: Integrated traceability and statistical monitoring ensure defect prevention and process control.
Fast-Response R&D Collaboration – The Shortest Path from Prototype to Production
Electronics evolve quickly; telecom certifications take time. We balance speed and risk:
- 24-hour quick quote & DFM feedback – upon receiving a 3D drawing, we flag risks (thin walls, sharp corners, undercuts).
- Soft tooling for validation – for 300–2,000 initial samples, using aluminum or rapid injection molds, lead time as short as 7–12 days.
- Staged ramp-up – from hand samples → pilot fixtures → production-grade tools → fully automated assembly/inspection lines, ensuring smooth NPI-to-MP transition.
