PCBONLINE is an advanced PCB manufacturer founded in 1999. Over the 24 years, it has built three PCB and PCBA manufacturing bases - one PCB factory in Jiangxi, one PCB factory in Jiangsu, and one PCB assembly factory in Shenzhen. All levels of production, from prototypes to large-scale manufacturing, happen on the same production lines. You may be curious - what are the manufacturing capabilities of PCBONLINE?

First, let's look into the PCB manufacturing capability. PCBONLINE focuses on high-end PCBs, such as the flexible (FPC), rigid-flex PCB, HDI, etc. Below is its PCB fabrication and assembly capabilities:
