The hard gold edge connector multi-layer PCB produced by Mingzhenghong Electronics Co., Ltd. is made of FR-4 TG 140 material. The board thickness is 1.0mm±0.1mm, and the copper thickness of the outer and inner layers reaches 1OZ. The product size is 160mm x 100mm. Through precise impedance control technology, the stable transmission of electronic signals is ensured. The surface treatment process combines electroplated nickel gold (ENIG) and selective hard gold plating "50u" to provide long-lasting wear resistance for the edge connection part (gold finger) to adapt to high-frequency plugging and unplugging usage scenarios. The number of product layers is 8, the minimum drilling is 0.2mm, and the minimum line width/space is 0.13mm/0.15mm respectively. The combination of green/yellow/black matte solder mask ink and white/yellow silk screen color creates clear appearance identification. This PCB is suitable for automotive, intelligent communications, industrial control, LED, power supply, medical and other fields, and can adapt to high-speed, high-frequency circuit requirements. The company strictly follows international quality and environmental management system certification to ensure the professionalism and high reliability of its products.
