Company Profile

A Shenzhen PCBA Factory Built Around Engineering Accountability

Shenzhen Aozite Technology Co., Ltd. was founded in 2015 to manufacture circuit board assemblies for OEM and ODM electronics brands worldwide.

Our factory sits in Shenzhen, Asia's densest electronics supply hub, which gives buyers same-day access to PCB fabricators, passive and active component stock, and tooling suppliers. That proximity is why we can turn a Gerber and BOM package into tested boards faster than suppliers who rely on long-distance procurement.

Every new project starts with a DFM review by engineers who have spent two decades on SMT lines. We flag footprint mismatches, obsolete or hard-to-source parts and panelization issues before a stencil is cut, so problems are solved on paper rather than on your first production lot.

Inside Our Smart SMT Factory in Shenzhen

As an integrated PCBA manufacturer, we combine component supply, PCB production and SMT processing on one site. Watch how a board moves from bare PCB to a tested assembly, the same process overseas buyers walk through during an on-site or video audit.

Buyer Guide

PCBA Sourcing FAQ for Overseas Buyers

Straight answers to the questions procurement and hardware teams ask most often before moving a PCBA project to a new supplier in China.

Need a capability overview?

Get our catalog with line equipment, inspection capability, board specifications and packaging options.

What files do you need to evaluate a PCBA project?
Send Gerber files (RS-274X or ODB++), a BOM with manufacturer part numbers, the pick-and-place (centroid) file and an assembly drawing. If you need functional testing, add the test specification, firmware and any test fixture requirements so FCT can be planned before production.
Do you support low-volume prototypes as well as mass production?
Yes. The same SMT lines handle engineering prototypes, pilot runs and volume production. Small batches carry a higher unit cost because stencil, line setup and component reel minimums are spread across fewer boards; our engineers advise on panelization and alternate parts to reduce that cost.
How do you control PCBA quality?
Quality is controlled in a closed loop: incoming material inspection, 3D SPI after solder paste printing, AOI after reflow, X-ray inspection for BGA and hidden joints, and functional testing before packing. Workmanship follows IPC-A-610 Class 2 by default, with Class 3 available on request, and the process targets a first-pass yield of 98.5% or higher.
Can you source the electronic components for us?
Yes. We offer full turnkey service where we procure all components through long-term supply partners, partial turnkey where you consign critical parts, and consignment assembly where you supply all materials.
Can overseas buyers audit the factory before ordering?
Yes. Buyers can schedule an on-site audit at our Shenzhen facility or a live video audit covering material storage, SMT lines, inspection stations and traceability records.
