Digital Security Board PCB
The Digital Security Board PCB is the rigidity PCB circuit board developed and produced by Shenzhen Quanhong Electronics Co., Ltd. the HDI board is made of FR-4 material, surface gold deposition and laser drilling. The minimum line width and line spacing can reach 75um and the minimum hole diameter can reach 0.1mm. The buried blind hole circuit board is widely used in digital cameras, notebooks, mobile phones and other electronic products and automotive electronics.
