Electronic and Electrical Industry (Core Application Field)

This is the main use of polyimide tape, which adapts to the strict requirements of precision electronic manufacturing, especially to the processing requirements of high-end electronic components.

Circuit board (PCB) processing: the core is used for gold finger protection. After the plug-in end (gold finger) of the circuit board is plated with gold/tin, adhesive tape is applied to prevent corrosion and contamination during welding and electroplating. After welding, no residual glue can be easily peeled off, which is necessary for PCB process. At the same time, it can be used for local shielding protection during wave soldering and reflow soldering of circuit boards.

Insulation and fixation of electronic components: adapt to resistors, capacitors, inductors, chips and other components for pin insulation and solder joint shielding to avoid short circuit; It can also fix electronic flat cables and wire harnesses, which is resistant to high temperature and does not release harmful substances, and is suitable for internal wiring of high-end electronic equipment.

Lithium battery manufacturing: In the processing of soft-package lithium batteries and cylindrical lithium batteries, it is used for battery lug insulation and battery wrapping and fixing, which can withstand the high-temperature process when battery is packaged, and has the characteristics of electrolyte corrosion resistance to ensure the safety and stability of batteries.

High-temperature electronic process shielding: when spraying, baking and sandblasting electronic components, it is used to shield and protect the parts that do not need to be treated, and it can withstand high temperature, and there is no residual glue and no damage to the substrate after shielding.

New Energy Industry (High-Growth Application Field)

Meet the high requirements of the new energy industry for temperature resistance, weather resistance and insulation, and adapt to the manufacture of high-end new energy products.

Photovoltaic module: It is used for shielding protection when photovoltaic cells are welded in series, and it is resistant to high-temperature welding process, ultraviolet rays and high-low temperature cycles, so as to meet the long-term use requirements of outdoor photovoltaic modules; It can also be used for insulation and sealing assistance of assembly frame and junction box.

New energy vehicles: used in on-board motors and electronic control systems for line insulation and high components.

Fixed temperature position: Inside the power battery pack, it is used for insulation and isolation between batteries and modules, and can withstand the high and low temperature and vibration environment when the car is driving.

Hydrogen energy equipment: It is used for shielding and insulation in high-temperature process when the core components of fuel cell are processed, which can withstand the corrosion of hydrogen environment and ensure the stability of the equipment.

Industrial Manufacturing and Processing Field

It is suitable for all kinds of industrial high-temperature processes, with strong universality and customization requirements.

Metal processing: when metal parts are sprayed, electrophoresed and electroplated at high temperature, they are used for shielding and protecting the non-processed surfaces, which can withstand high temperature and do not react with metal substrates; It can also be used for surface protection of metal stamping and bending to prevent scratching.

Processing of plastics and composite materials: When high-temperature resistant plastics and carbon fiber composite materials are molded, they are used for mold shielding and product positioning, and can withstand high molding temperature, and there is no residual glue after peeling to ensure the surface smoothness of products.

High-temperature baking and curing: It is used to cover the parts that don't need curing in the high-temperature baking and curing process of various products (such as hardware, plastics and coatings), and can withstand the high temperature and adapt to different baking processes.

Other Niche High-End Uses

Semiconductor manufacturing: used for wafer surface shielding and pin insulation in semiconductor wafer cutting and packaging processes, which can withstand high packaging temperature and has high cleanliness without dust pollution.

Medical equipment: used in high-end medical instruments (such as high-temperature sterilization equipment and precision diagnostic instruments) to insulate and fix internal electronic components, which can withstand high-temperature sterilization process and meet medical-grade environmental protection standards.

High-temperature label substrate: Some polyimide tapes can be used as high-temperature resistant label substrate for labels that need to be kept in high-temperature environment for a long time (such as engine and boiler parts).

Complement the core adaptation advantages (fitting the properties of special adhesive customization and benchmarking)

Core characteristics support: wide temperature range, excellent insulation, acid and alkali resistance/salt fog/ultraviolet resistance, peeling without residual glue, which can benchmark international similar high-end products.

Customized adaptation: products with different thickness, viscosity and temperature resistance can be customized according to the needs of different industries to adapt to different processes and scenarios, and at the same time, they have cost advantages and cost performance ratio is higher than that of international brands.

Frequently Asked Questions

Q: What is polyimide tape and why is it called "Golden Finger Tape"?

Polyimide tape is a high-performance adhesive tape made from a polyimide film base coated with a silicone pressure-sensitive adhesive. It is commonly called "Golden Finger Tape" because one of its primary uses is protecting the gold finger (edge connector) area of printed circuit boards (PCBs) during electroplating and soldering processes. Its golden-amber color also contributes to this nickname.

Q: What is the maximum temperature resistance of polyimide tape?

All models in the HY200 series offer a temperature resistance of up to 260°C (500°F). This makes polyimide tape suitable for high-temperature manufacturing processes such as wave soldering, reflow soldering, high-temperature baking, and various industrial curing processes without degrading or leaving adhesive residue.

Q: Does polyimide tape leave residue after removal?

No. One of the key advantages of polyimide tape is that it can be cleanly peeled off without leaving any adhesive residue on the substrate, even after exposure to high temperatures. This is critical in precision electronics and semiconductor manufacturing where surface cleanliness is essential.

Q: What industries use polyimide tape most commonly?

Polyimide tape is widely used across several industries: the electronics and electrical industry (PCB manufacturing, component insulation, lithium battery production), the new energy sector (photovoltaic modules, new energy vehicles, hydrogen energy equipment), industrial manufacturing (metal processing, plastic molding, high-temperature curing), and niche high-end applications including semiconductor manufacturing and medical equipment.

Q: Can polyimide tape be customized for specific applications?

Yes. Products with different thickness, viscosity, and temperature resistance levels can be customized to meet the specific requirements of different industries and processes. This flexibility allows manufacturers to select or order the exact specification needed for their application, from ultra-thin 0.030mm total thickness variants to thicker 0.18mm versions, while maintaining cost advantages over international brands.

Q: Are HY200 series polyimide tapes equivalent to 3M products?

Several models in the HY200 series are direct equivalents to well-known 3M products. For example, HY200-2B is equivalent to 3M 98C-12, HY200-2D is equivalent to 3M 7413D, and HY200-2F is equivalent to 3M 98C-1. These equivalents offer comparable performance in terms of temperature resistance, adhesion, and insulation properties, while providing a more cost-effective alternative with higher cost performance ratio.
