The circuit board with staged gold fingers/long-short gold fingers breaks through the original concept of gold fingers in design. The gold fingers are designed as segmented or staged structure, which aims to form an effective time difference in the transmission process of the signal, facilitate the signal transmission, realize the hot plug-in technology, and facilitate the subsequent upgrading and maintenance of the product. It can be seen that the market development prospect of staged gold fingers circuit board is broad and the profit is high, but it is also limited by the process difficulty. At present, there are only a few manufacturers in the industry that can achieve the production of staged gold fingers/long-short gold fingers. Rocket PCB is a leading PCB supplier of high-end PCB, which can provide various staged and long-short gold fingers PCB production.
