Gold finger is the gold-plated connectors that are on the edges of the printed circuit board prototype. They are similar to fingers in that they are long and narrow, usually, the fingers are done by flash gold (hard gold) and the gold thickness is requested to be from 3u'' to 50u'' , because fingers are mainly used for plugging for many times.
Our factory is engaged in PCB manufacturing and offering customized high precision gold fingers printed circuit board with hard gold au20u'' at competitive price. High reliability, strong diversity and expert advice are our characteristics.
The typical chamfer angle for gold finger PCB is 20°,30°,45°and with tolerance±5°
