Amber Polyimide PCB Masking Tape (Gold Finger)
进口杜邦PI聚酰亚胺薄膜+硅胶背胶，琥珀黄色，耐温260°C。PCB波峰焊/SMT回流焊金手指与镀金端子遮蔽专用，撕除无残胶。
黄色PI金手指胶带（俗称金手指胶带）以杜邦Kapton®级聚酰亚胺薄膜为基材，复合耐高温硅胶压敏胶。琥珀黄色透明基材是其标志性外观，作为PCB制造过程中的关键耗材，广泛用于波峰焊、回流焊工序中对金手指触点、镀金端子、敏感元器件的临时遮蔽。
聚酰亚胺基材在 260°C 高温下持续工作不变形、不熔融，硅胶背胶在高温过炉后撕除依然干净无残留，避免污染镀金表面。透明黄色便于操作员目视定位需遮蔽的位置，提升贴附效率。
典型应用
PCB 波峰焊金手指遮蔽；SMT 回流焊敏感元件保护；电镀/喷涂工艺遮蔽；变压器线圈固定；柔性电路板（FPC）加固。
