Jiaqing Circuit was founded in 2012 in Shenzhen, China. We own a 5,0000 square meter manufacturing plant with a monthly PCB production capacity of 100000 square meters, capable of manufacturing 2-48 layer PCBs.
We deliver one-stop solutions including PCB design, PCB fabrication, BOM component sourcing and SMT assembly. Our products serve high-end industries such as automotive electronics, industrial control, AI computing, telecommunications and medical electronics.
With mature manufacturing processes and stable supply-chain support, we handle rapid prototyping, small-batch and mass-production orders. We strive to provide reliable custom-printed circuit board solutions for global high-tech electronics customers.
We are committed to providing one-stop, full‑process electronic manufacturing services covering four core areas: BOM sourcing, CAD design, PCB fabrication, and SMT assembly. In BOM sourcing, we offer professional component selection and supply chain procurement to ensure material quality and on‑time delivery. Our CAD design capabilities handle complex, high‑density, and high‑speed board designs, supporting up to 48 layers, 40,000 pins, and 28 Gbps differential signaling, meeting the most demanding requirements. Our PCB fabrication utilizes advanced precision processing, supporting minimum trace width/spacing of 2 mil, minimum mechanical drilled hole of 6 mil, and laser microvia of 4 mil, to satisfy high‑reliability product needs. Our SMT assembly is equipped with state‑of‑the‑art placement lines, enabling high‑accuracy surface‑mount and assembly. By integrating the entire chain from material procurement and design development to production assembly, we help customers effectively shorten R&D cycles, reduce overall costs, and enhance the market competitiveness of their final products.
