About Union

Established in 2010, Union Circuits is well-known as a professional PCB manufacturer located in Shenzhen, China, dedicated to produce and sale Quick-turn, Prototype, small to medium volume PCBs. We have two PCB factories, one located in Shenzhen focus on prototype and small volumes PCB orders, another in Jiangmen of GuangDong, China focus on small to medium volumes. Both factories work seamlessly to offer our clients with the best services.

Our PCB Assembly services started in 2014, equipted with total 10 SMT lines including 4 for prototype PCB SMT and 6 full SMT lines for production. This expansion has enabled us to offer comprehensive solutions, from PCB fabrication to assembly, all under one roof, enhancing our service offerings and efficiency to the next nevel.
