Equitment & Manufacturing

At CNTCOM, our manufacturing strength is built on a fully integrated setup covering FPC fabrication, SMT assembly and in-house quality assurance. Every stage — from materials to final inspection — is managed with a consistent process and modern production equipment, giving customers stable output and predictable lead times.

Manufacturing & Testing Equipment


Our production environment is built around a comprehensive suite of equipment that supports every stage of FPC fabrication and SMT assembly. Each machine plays a defined role in maintaining process stability, from material preparation and circuit formation through to soldering, inspection and final verification. With dedicated tools for imaging, drilling, laminating, reflow, optical inspection and electrical testing, we’re able to monitor quality in real time and keep performance consistent from samples to ongoing mass production.

Alongside our main production lines, we maintain a fully equipped inspection area that handles dimensional checks, electrical continuity, solder joint analysis and reliability assessment. This combination of manufacturing and testing systems allows us to manage each batch with traceability and confidence. The tables below provide a detailed overview of the key equipment deployed across our factory floor and quality lab.

Materials We Use

We work with a stable and proven material system that supports reliable FPC production and downstream SMT assembly. All base films, copper foils, adhesives, surface finishes and stiffeners are sourced from vetted suppliers and checked upon arrival to ensure consistency before entering the line. Each material category plays a specific role in achieving dimensional accuracy, solderability and long-term reliability, especially for applications that demand high mechanical flexibility or environmental resistance.

The table below outlines the primary materials used across our processes, covering everything from core substrates to protective films and finishing options. This provides a clear view of the material structure behind our products and the standards we maintain throughout manufacturing.

Manufacturing Process & Production Control

CNTCOM operates a fully integrated manufacturing process supported by comprehensive production and testing equipment across FPC fabrication and SMT assembly. Dedicated machinery is used throughout fabrication, surface finishing and protective lamination to maintain accuracy, process stability and repeatable output. Automated inspection and electrical verification are embedded within the production flow, allowing quality to be monitored and controlled at multiple stages.

Quality assurance is applied through two dedicated FQC and FQA checkpoints, covering both pre-assembly and post-assembly stages. This layered inspection approach helps identify potential issues early and ensures that finished products meet defined electrical, mechanical and performance requirements before shipment. Combined with final functional testing and profiling, this structured quality control framework supports consistent results across prototypes and long-term volume production.
