SMT 螺帽、緊固件與螺紋銅柱
U-TEK SMT 螺帽、緊固件與螺紋支撐柱為專為全自動化 PCB 組裝製 程所設計的精密緊固解決方案，可相容於標準 SMT 設備及 IR 紅外線 迴焊（Reflow Soldering）製程。產品可提供穩定可靠的機械固定功 能，同時提升生產效率與組裝可靠度。
為滿足高速自動化 SMT 組裝需求，U-TEK SMT 螺帽頂部貼附耐高溫 PI（Polyimide，聚醯亞胺）薄膜，使標準 SMT 真空吸嘴能夠穩定吸取元件，並精準放置於 PCB 指定位置。完成迴焊後，可將 PI 薄膜移除，在 PCB 上形成潔淨、穩固且可靠的螺紋固定點，供後續零組件鎖附與組裝使用。
U-TEK SMT 緊固件提供多種螺紋尺寸、本體直徑、安裝高度、表面處理及包裝方式，可依不同 PCB 設計與自動化組裝需求進行選擇。U-TEK SMT 緊固解決方案結合自動化組裝效率、機械固定可靠度與設計彈性，適用於對生產效率及可靠性要求較高的先進電子產品與 PCB 組裝應用。
