A Fuzz Button is a high performance electrical connection material used to connect two parts of an electrical circuit together, for example an IC to a PCB or two PCBs to each other. Fuzz Buttons consist of a single strand of gold-plated beryllium copper wire compressed into a dense, sponge-like cylindrical shape. Their diameter can range from a few tenths of a millimetre to a millimetre.
毛纽扣是一种高性能的电气连接材料，用于将电路的两个部分连接在一起，例如ic到pcb或两个pcb到彼此。毛纽扣由一根镀金铍铜线组成，被压缩成一个致密的海绵状圆柱形。它们的直径可以从十分之几毫米到一毫米不等。

A Fuzz Button is a high performance signal contact typically fashioned from a single strand of gold-plated berylium-copper wire formed into a specific diameter of dense cylindrical material, ranging from a few tenths of a millimetre to a millimetre. They are often used in semiconductor test sockets and PCB (board-to-board) interconnects where low-distortion transmission lines are a necessity.
毛纽扣是一种高性能的“信号触点”，通常由一根镀金铍铜线制成，形成一个特定直径的致密圆柱形材料，从十分之几毫米到一毫米不等。在需要低失真传输线的半导体测试插座和pcb（板到板）互连中，它们经常使用。
