WHO USES IT
Who Uses It · Which Industries
See which scenario matches your application and jump directly to the relevant tape category.
Electronics Manufacturing Services (EMS/PCBA)
Soldering Masking · EMI · Conformal Coating
Tapes must withstand soldering ovens, conformal coating, and EMC testing in the same line, reducing defects from adhesive residue on boards.
Transformers · Motors · Coil Winding
Coil Wrapping · Insulation · UL/CE Certification
The end goal is certification. Tapes with clear UL ratings are required for reference when submitting for certification.
Failures don't appear in the factory, but at the customer's home 2-3 months later. Requires strong adhesion without edge lifting.
Q&A
Frequently Asked Questions
Which tape is suitable for soldering masking (wave / reflow)?
Polyimide Tape (Kapton), such as WE-PI50, withstands high temperatures and peels off cleanly without leaving adhesive residue on the board, eliminating the need for individual IPA washing.
How does "conductive" copper tape differ from regular copper tape?
It depends on the adhesive layer — conductive versions allow current to flow through the adhesive, creating a continuous ground path ideal for EMI shielding. Regular adhesive acts as an insulator, which might secure all points but still fail EMC testing.
Can I order custom widths / die-cuts, and is there a high MOQ?
Yes, we have our own slitting, die-cutting, and laminating machines to cut to your exact sizes/designs. No high MOQ is required, supporting everything from R&D to mass production.
Which tape should be used for transformer / motor applications requiring UL certification?
Polyester insulation tape, such as 3M 1350F-1, has a UL rating (130°C) and can be used as a reference during certification submission, reducing the risk of failing UL/CE certification.
Can I request samples for testing before placing a real order?
Yes, simply send us your job specifications. Our team will guide you from the first step to the recommended model, and provide samples for you to test under actual production conditions before making a decision.
Where do the specifications (temperature, UL) on this page come from, and how reliable are they?
All stated values are referenced directly from the manufacturer's Technical Data Sheet (TDS), such as 3M, and Wetape's own specification catalogs. If you need to use them for official documents, such as applying for UL/CE, we recommend requesting the latest TDS file from our team for clarity before actual use.
Premium industrial-grade dead-soft aluminum foil tape (0.12 mm) with transparent synthetic acrylic adhesive. Delivers extreme temperature resistance from -54°C to 149°C. Features excellent heat and light reflection, along with robust protection against moisture, chemicals, and flames. Highly conformable, making it ideal for aerospace paint stripping masking, thermal shielding, and wire harness wrapping.
Polyimide Film Tape 5413 features DuPont™ Kapton® polyimide film and silicone adhesive, used for PCB masking and high-temperature applications. It is resistant to chemicals and UV radiation. The tape is amber in color with a thickness of 2.7 mm.
Copper tape, only 0.05 mm thick and 33 m long, is used for protecting small electrical circuit components, repairing and modifying circuit boards, and providing extra protection for joints, seams, and insulated wires.
