About HSX
Shenzhen Huashengxin Circuit Co., Ltd. (HSX) was founded in Shenzhen in May 2015 to build difficult prototypes quickly: HDI with blind and buried vias, high-layer precision boards and LED display boards.
We still work that way. A team of more than 60 engineers reviews every file, and every process, from lamination and surface finishing to electrical test, runs in our own 12,000 m² plant in Songgang, Bao’an District. In 2025 the factory shipped about RMB 130 million of boards.

HSX / Our factory
The equipment behind the specification.
Original photographs from our Shenzhen factory. Explore the manufacturing process and the equipment used to build and inspect your boards.

CNC drilling
Mechanical drilling produces through-holes and defined drill structures. Our drilling workshop supports prototypes and production orders.

VCP copper plating
Continuous plating equipment supports the copper deposition and via-fill processes used in PCB manufacture.

Electrical testing
Every board is tested for electrical opens and shorts before shipment. The factory has 27 flying-probe testers and three fixture testers.
Send your design. Let’s build it properly.
Upload Gerber or ODB++, stack-up and quantities. Standard PCB quotes usually take 30 minutes in working hours; HDI, rigid-flex and special materials usually take up to 24 hours.
