Gold fingers connect a circuit board to a source of power – one of the major applications of contact edges is linking a module circuit board to a source of power on the linking profile of a giant board.

They facilitate the transmission of signals – categorically, gold fingers connect with other circuit boards to facilitate signal transmission between the peripheral and central Health Care PCB.

Thirdly, gold finger interconnects modules in one Health Care PCB. – traditional electronic devices consist of multiple stable modules that cannot be interconnected easily in the same Health Care PCB. The invention of flex PCBs facilitated the interconnection of several modules within one Health Care PCB.

They create space for future improvements. Think about a motherboard lacking ports and expansion slots? How does that even sound? How can it function, and how can designers improve it without introducing expansion slots? It is impossible. You cannot link the input and output devices. Designers cannot enhance their keyboard or mouse. Generally, without gold finger circuit boards, electronic devices cannot be improved.
