PCB Process

1.Product Hole: Minimum metallized hole diameter: (0.1±0.05); Minimum non-metallized hole diameter: None

2.Product Circuitry: Minimum circuit width: 0.11±0.02mm; Minimum circuit spacing: 0.055±0.02mm

3.Product Solder Mask & Characters: Solder mask opening 0.7±0.075mm; Character silkscreen line width: 0.125mm

4.Finished Product Dimensions: 62.6*7.3mm

5.Surface Finish: Immersion Gold 1-2U

6.Product highlights: Due to the limited space in smart rings, the rigid-flex PCB must be ultra-thin, and the connection 

points between the rigid PCB areas and the flexible PCB areas are extremely narrow, posing significant manufacturing 

challenges. This product is primarily used in Bluetooth hard-network smart rings, health monitoring smart rings, and 

fitness tracking smart rings.
