More Information
Summary:The invention discloses a fuzzy button made by random winding and filling of metal wires. The random winding is better for transmission of high-frequency signals, the size is smaller, contact is more reliable, the randomly wound wires are suitable for connecting any metal surface (pad) to a pad, and no welding or crimping is required. The fuzzy button has the advantages that high signal transmission rate allows signal frequency to be higher than 20 GHz; compressed interconnection needs no welding or crimping; with low mounting speed, the fuzzy button is applicable to an LGA (land grid array) integrated circuit socket and to perpendicular interconnection between PCBs (printed circuit boards); the problems in PCB via-holes and surface mount welding are solved; weld-connecting is avoided, and mounting, upgrading and system maintenance are facilitated; connections range from 1 to 7000; the fuzzy button is available for contact spacing as low as 1mm or higher.
