What Is Golden Finger High Temperature Tape? (PI Kapton Tape Definition)
Golden finger high temperature tape is a professional polyimide (PI) film adhesive tape based on high-quality PI film substrate and coated with imported high-temperature silicone pressure-sensitive adhesive. It gets its mainstream name “golden finger tape” because it is most commonly used to protect the gold-plated contact terminals (golden fingers) on PCB circuit boards during the soldering process. As a premium solder masking tape for PCB, it is customized for high-heat electronic manufacturing scenarios that require zero residue and precise shielding.
Different from ordinary PET tape and ordinary masking tape, standard
Kapton polyimide tape features a unique amber transparent color, excellent electrical insulation, ultra-high temperature resistance, and chemical corrosion resistance. After high-temperature baking, reflow soldering and wave soldering processes, it can be peeled off cleanly without leaving any adhesive residue or damaging the surface of precision components, making it the top choice for
SMT high temperature masking tape.
Core Features of Polyimide Kapton Golden Finger Tape | High Heat Resistant Tape
Renowned for its reliable and stable performance, golden finger high temperature tape outperforms ordinary adhesive tapes for industrial high-heat applications. Its core technical advantages are listed below:
-
Ultra-high temperature resistance: This heat resistant Kapton tape supports continuous operating temperatures ranging from 250°C to 260°C and can tolerate instantaneous peak temperatures up to 320°C. It maintains stable adhesion and flatness during SMT reflow soldering and wave soldering, with no melting, warping, or detachment, fully compliant with standard PCB high-temperature manufacturing processes.
-
Zero residue after peeling: Formulated with high-purity industrial silicone adhesive exclusively for PCB golden finger protection tape, the tape never softens or decomposes under high-temperature conditions. It removes completely clean after heating, leaving no sticky residue on PCB circuits or gold-plated contacts, eliminating post-process cleaning work and preventing secondary component damage.
-
Excellent insulation performance: Rated H-class for electrical insulation, this tape effectively prevents current leakage and short-circuit risks. As a professional high temperature insulation tape, it is widely used for insulation wrapping and fixation of motors, transformers, and new energy lithium battery components.
-
Superior chemical stability: Resistant to solder flux, industrial solvents, weak acid, and alkali corrosion, it adapts perfectly to complex and harsh industrial processing environments with long-lasting performance.
-
RoHS compliant & eco-friendly: Contains no hazardous substances, fully meeting international environmental protection standards, suitable for exported electronic products and global industrial manufacturing requirements.
-
High toughness & perfect conformability: The uniform PI film substrate delivers excellent tensile strength and flexible ductility. It fits tightly on curved surfaces, narrow gaps, and irregular parts, achieving precise and seamless masking protection.
