About QIANSPEC

Company

Shenzhen Qiantang Technology Co., Ltd. was founded in 2014 and is based in Longhua District, Shenzhen. We design and manufacture RF, audio, and vision test equipment, microwave components, and automated production line integration for smart terminal, communication equipment, and consumer electronics manufacturers.

The company is recognised as a National High-Tech Enterprise and as a "Specialised and Sophisticated" enterprise — a Chinese national designation for small and mid-size manufacturers with a focused technical niche. Published figures list a 10,000 m² facility, approximately 50 employees, and two production bases.

What we actually do

Most of our work starts with a measurement problem rather than a product request. A customer has a device that needs to be tested at line speed, or a measurement that will not repeat, or a shield box that works on the bench and fails on the floor. We build the hardware around that specific problem.

That means a large share of what we ship is configured rather than catalogued: cavity dimensions, feed-through complement, fixture geometry, actuation method, and control protocol are set per project. Where a published figure depends on the configuration, we state the condition instead of the number alone.

Product lines

RF shielded enclosures — manual benchtop, pneumatic production, drawer-type, dual-position stations, SMT download boxes, acoustic and abnormal-noise cabinets.

RF components — step attenuators (push-button and rotary), programmable attenuators, 4×16 matrix switches, SPDT switches, high-pass filters, low-noise amplifiers, and phase-stable test cables.

Production test systems — 5G multi-antenna coupling, automated RSSI, UWB, ECG, PCBA functional test, RSE screening, and vision defect inspection.

Integration — fixtures, control electronics, and line-side interfaces for automated production.

How we work with overseas customers

English-language documentation is provided for the products listed on this site, and technical correspondence is handled in English. Where a specification depends on the application, we will say which values are fixed and which need verification on your sample before you commit to a purchase order.

We would rather lose an order than ship a shielding figure that does not hold in your fixture.
