About JIEZHOU

Jie Zhou Enterprise Co., Ltd.

Jie Zhou Enterprise Co., Ltd. was established in 1989 in Tainan, Taiwan. With over 30 years of experience, the company originally focused on purchasing electronic connector parts, processing, assembling, and selling the finished products.

To provide more diverse options and enhance product competitiveness (high quality, reasonable price, and short lead time), we introduced high-precision CNC machining equipment (processing accuracy < 0.005mm) after the year 2000.

We not only sell electronic connectors but also do turning, manufacturing, assembling, and producing them. With nearly 36 years of experience in the production of electronic connectors, Jie Zhou has now become a professional manufacturer of RF connectors.

Our various electronic connectors are widely used in communications, automotive, drones, AI, medical, military, and industrial control equipment. In addition to connectors, we have also undertaken many OEM/ODM orders in recent years, further developing and producing various integrated products, such as copper, aluminum, stainless steel, and plastic parts. Our products are widely applied in various industries and in our daily lives, such as electronic components, precision equipment, automotive, medical devices, aerospace, military, stamping parts, etc.

High-Precision CNC Turning Solutions

Strict process control and wide material applicability establish a solid foundation of trust.

Ultimate Tolerance Control

We have the ability to process small parts with dimensional tolerances reliably controlled within ± 0.01mm, meeting the most stringent industrial standards.

Multi-Axis Composite Processing

We own Swiss-type and cam-type CNC lathes, supporting side milling, drilling, and tapping in one operation to ensure absolute concentricity and production efficiency.

Wide Material Adaptability

We are skilled in machining stainless steel (SUS303/304/316), brass (C3604), aluminum alloys, and various engineering plastics.

Technical Specifications

Processing diameter: 0.5mm - 27mm
Surface roughness: up to Ra 0.4µm↓
Secondary processing services: Heat treatment, plating (gold, silver, nickel), anodizing, precision measurement, and complete inspection reports

RF Connectors Precision Parts Manufacturing Expert

Our parts are widely used in 5G communications, aerospace, medical equipment, and automated testing instruments. We understand that even a micron of error can affect the return loss of high-frequency signals.

Center Contact

Made from beryllium copper or phosphor bronze through precision turning to ensure optimal conductivity and durability for insertion and extraction.

Body & Shell

High-precision thread machining (SMA, SMB, N Type, BNC), ensuring tight coupling.

Insulator

Precision turned PTFE (Teflon) parts to maintain impedance stability (50 ohm / 75 ohm).

Quality Commitment

Signal Integrity: Strict control of burrs and surface flatness to reduce insertion loss.
Cleanliness Management: Custom packaging solutions tailored to product requirements.
