Polyimide tape (commonly known as Golden Finger Tape) serves as an essential category of high-performance specialty adhesive products. Engineered with superior high-temperature endurance, acid and alkali resistance, and strong electrical insulation, it is designed for demanding manufacturing environments across core industries including electronics and new energy.
This is the primary application sector for polyimide tape, addressing the rigorous requirements of precision electronic manufacturing, particularly in the processing of advanced electronic components.
Primarily utilized for gold finger protection. Applied after circuit board plug-in fingers are gold/tin plated to prevent corrosion and contamination during soldering and electroplating. Easily peels off without residual glue, making it indispensable for wave soldering and reflow soldering shielding.
Applied to resistors, capacitors, inductors, and IC chips for lead insulation and solder joint shielding to prevent short circuits. Also securely fastens flat cables and wiring harnesses without releasing harmful substances under high temperatures.
Used for battery lug insulation, wrapping, and fixation in pouch-cell and cylindrical lithium batteries. Withstands high-temperature packaging processes and provides excellent resistance to electrolyte corrosion, ensuring battery safety and stability.
Shields non-treatment areas during spraying, baking, and sandblasting of electronic parts. Withstands intense heat while leaving zero residue and causing no substrate surface damage upon removal.
Meets strict industrial standards for thermal stability, weatherability, and electrical insulation in next-generation clean energy product manufacturing.
Provides shielding protection during PV cell series welding, enduring high-temperature soldering, UV radiation, and severe thermal cycling. Also assists in frame insulation and junction box sealing for outdoor reliability.
Employed within EV drive motors and electronic control systems for reliable line insulation and critical component protection against thermal stress.
Provides insulation, isolation, and vibration-resistant fastening between cells and modules inside vehicle power battery packs across harsh high- and low-temperature driving conditions.
Used for shielding and thermal insulation during fuel cell core component processing, resisting hydrogen environmental corrosion and maintaining system longevity.
Engineered for diverse thermal manufacturing environments, featuring wide versatility and fully customizable specifications.
Protects unworked sections during high-temperature metal spraying, electrophoresis, and electroplating without chemical interaction with metal bases. Also protects surfaces against scratches during stamping and bending.
Used for mold release masking and component positioning during high-temperature plastic molding and carbon fiber composite curing, leaving no residue to maintain surface integrity.
Shields designated areas during the thermal curing processes of hardware, plastics, and surface coatings, consistently adapting across various industrial oven operations.
Applied for wafer surface masking and pin protection during wafer dicing and packaging workflows, delivering dust-free ultra-cleanliness and high-temperature tolerance.
Utilized within precision diagnostic instruments and autoclave sterilization machinery for internal electronic insulation, conforming to medical-grade environmental standards.
Serves as a resilient facestock material for barcoding and tracking labels on components subjected to sustained heat, such as automotive engines and boiler systems.
Offers a broad operational temperature range, exceptional dielectric breakdown insulation, salt fog/acid/alkali resistance, UV stability, and residue-free release that benchmarks global high-end brands.
Tailored thickness, adhesion levels, and heat capabilities designed specifically to match individual manufacturing processes, paired with substantial cost efficiencies over international equivalents.
Polyimide tape, also referred to as Golden Finger Tape, is widely deployed in high-heat manufacturing environments. Primary applications include PCB gold finger masking during wave soldering, lithium battery lug insulation, solar panel assembly, and protective masking throughout metal electroplating and powder coating.
Our polyimide tapes provide continuous temperature resistance up to 260°C (500°F). This thermal threshold makes them optimal for reflow ovens, solder baths, and powder coat curing chambers without thermal degradation or peeling.
No. Engineered with high-grade silicone adhesives, our polyimide tapes strip away cleanly from electronic boards, metals, and composite substrates even after exposure to intense thermal baking or harsh electroplating solutions.
Yes. We supply customized film thicknesses ranging from 0.015mm to 0.125mm, total thicknesses up to 0.18mm, and adjustable steel adhesion levels (2.5 to 6.5 N/25mm) engineered to match your precise application requirements.
In clean energy manufacturing, it delivers cell insulation and harness stabilization in EV power battery packs, protects series busbar welding in photovoltaic modules, and offers chemical and heat protection for fuel cell components.
Selected models such as HY200-2B, HY200-2D, and HY200-2F serve as direct equivalents to industry standards including 3M 98C-12, 3M 7413D, and 3M 98C-1, delivering comparable dielectric properties and thermal stability with superior cost efficiency.
