Kapton is a polyimide film used in flexible printed circuits (flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments. Invented by the DuPont Corporation in the 1960s, Kapton remains stable across a wide range of temperatures, from 4 to 673 K (−269 to +400 °C).
Chemical structure of Kapton, a polyimide. Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics.With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, such as high temperature fuel cells, displays, and various military roles.
Drawing of a tape-automated bonding carrier and definitions of various parts of the TAB assembly. Tape-automated bonding (TAB) is a process that places bare semiconductor chips (dies) like integrated circuits onto a flexible circuit board (FPC) by attaching them to fine conductors in a polyamide or polyimide (like trade names Kapton or UPILEX) film carrier.
Polyimide pressure delicate adhesive (PSA) tape is in fact produced up of two separate actions. The very first will be the manufacture in the Polyimide film tape, itself (the generic name of DuPont’s trade name Kapton®), along with the second is applying an adhesive backing based on the meant application. Polyimide Tape is produced up of two ...
Image of flexible printed circuits prior to de-panelization. An Olympus Stylus camera without the case, showing the flex circuit assembly. Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic components on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester [1] film.
Kapton is a type of polyimide film, has very low outgassing. Kapton is discouraged if a ceramic alternative can be used. [3] Some elastomers have sufficient vacuum properties to be employed in vacuum o-rings: NBRs, (nitrile rubber), commonly used for demountable vacuum seals (bakeable only up to 100 °C).
