目前已量產之各式PCB,除日本松電工的ALIVH增層法板材,係另採杜邦商品Thermount之不織布纖維外,幾乎所有板材都採用E-glass玻纖布作為補強。此等玻纖布的製造是先從高溫1200℃熔融玻璃漿的紡位(Bushing)中,同時擠出多支同一直徑的玻 璃絲(Filament),之後經上漿(Sizing)處理的多根(200~400)細絲,再經旋扭與纏繞即成為...
Simply put, SMT refers to Surface Mount Technology, which is an PCB assembly technique that helps arrange components on the circuit board. SMD, on the other hand, refers to Surface Mount Devices. These are components fitted onto the circuit boards. They are designed to be mounted directly on...
Surface mount technology(SMT) utilizes components that have terminations or “lands” that solder directly to matching pads on the surface of PCBs, as opposed to inserting leads into holes. Some benefits of SMT components include: Smaller size – More compact, portable products ...
