Laser cutting of polyimide

eurolaser offers laser cutter especially configurated for foils

The cutting of polyimide (also known as Kapton ^®) with CO₂ laser systems is charactersied by its high precision and flexibility. The varied offer of eurolaser is especially suitable for laser cutting of thin foils made of polyimide. With the parallel use of CO₂ laser and knife bits on one machine, you turn your eurolaser system into an universal cutter.

What advantages have laser cutting of polyimide (PI)?

Filigree details without material damages

Very high precision during laser cutting

Minimum oxide formation thanks to optimised nozzle and exhaust concept

Precision in the µm range
No material fixation necessary due to vacuum table
No flaking of the material as is the case with punching due to contact-free and force-free processing

No knife cleaning – no sticking of the single parts after cutting
No tool wear and thus, a constantly high cutting quality
High flexibility in contour – without tool preparation or tool changes

We recommend the following laser systems for cutting of polyimide:

Material information for laser cutting of polyimide (PI):

Polyimides are often used in the form of thin, semi-transparent flexible circuit boards but also for the isolation layers of energy storage cells and for insulation applications in alternative energy technologies. Polyimide is also used in fibre form for filtering gases. Its outstanding material properties and high temperature resistance make both extremely low and high temperature applications possible (-256° to 400°C), the reason it is so widely used in the aerospace sector. Kapton films can be laminated, metallised or coated with adhesives. Laser processing generally takes place after the electronic components are mounted and often in combination with other substrates or films.
