PCB Manufacturing Capability

2025-12-12

Golden Triangle Group Ltd is professional PCB manufacturing on quick-turn PCB prototyping, PCB mass production and PCB Assembly, it can be supported high mix and low-volume production located in Shenzhen China.

You will find information here relating to the specific materials and the PCB technologies or product types that we currently produce and suport, as well as some of the tolerances which we can achieve.

on rigid printed circuit boards, which are built with premium materials and advanced manufacturing processes, ensuring excellent mechanical stability, thermal resistance, and electrical conductivity—ideal for devices requiring structural rigidity and long-term reliability.

Provide PCB files( gerber file, cam file, .pcb, .pcbdoc format)

Thanks for reviewing our PCB capabilities. Please provide your PCB files in the format of gerber file, cam,gerber file, .pcb or .pcbdoc to our sales team. Please try best to offer gerber file. But if you only have DXP file with (.pcb/.pcbdoc) format, we will use ALtium Designer23.21 and 10.0 software to transfer to gerber.
