The Many Uses of Kapton Tape > 자유게시판

Kapton tape or polyimide tape is among the most versatile materials in the semiconductor industry. It is helpful in masking specific regions of semiconductor wafers that require processing. Earlier photoresists or oxides were the main line of defense in etch resistant masking. Polyimide tape's inherent characteristics of excellent dielectric strength and the capability of withstanding wide temperature fluctuations have allowed it to become the defacto masking material. It is also cheap and allows last minute alteration which is simply a matter of masking the new area with Kapton or removing the tape to expose the PCB for the etching process.

Polyimide As a Masking Tape In Semiconductor Industry

Masking Procedure: Kapton tape is available in rolls of thin strips of half an inch and above. Taking the appropriate width of the allows easier application on the region where the masking is required. The tape adheres to the substrate by its adhesive backing. Tape thicknesses vary from as low as onemil (one-thousandth of an inch) and above. Polyimide tape is common in wave soldering applications. Shielding gold fingers on circuit boards prevents unwanted electrical contacts.

Kapton applications in motors



Kapton CR polyimide films have significantly improved generator and electric motor performance. The magnet and wire industry has achieved tremendous success due mainly to the properties of polyimide film. The motors have a longer life and 마스킹테이프제작 increased durability. The insulation space is much less compared to earlier insulating materials as Kapton films occupy less space due to being thin. The ability to withstand continuous exposure to wide temperature changes makes polyimide the perfect material for space applications. In traction motors and transformers the polyimide delivers excellent corona resistance under severe environment conditions. Polyimide film provides superior overload protection which extends motor durability in extreme conditions. The other properties such as high flammability rating and excellent chemical resistance to solvents make Kapton the go-to material for high-performance insulation.

For the DIY hobbyist, Kapton film is a wonder material used instead of standard black electrical tape. If a hot soldering iron touches the Kapton tape, it will not melt, unlike the normal insulation tape. The tape also does not stretch, and the adhesive leaves no residue or marks making it easy to remove.

Dupont discovered the wonder material Kapton in the 60s; China has become an industry leader in the supply of polyimide tapes. Kapton tape manufacturers from China have to thank Tianjin Tianyuan Electronic Material Co., Ltd for their research and development projects in promoting polyimide production. Tianjin Tianyuan is a leading Kapton tape supplier in China and acknowledged by their peers for their leadership status.
