Femtosecond lasers ensure high quality polyimide micromachining

Precise machining of small features in thin materials calls for ultrafast, high-power lasers. In our application laboratory, we have seen good results when machining very small features in 25 µm thick polyimide film using our IR and green wavelength ORIGAMI XP lasers.

Polyimide (or PI or Kapton) is a thin film widely used in the medical and microelectronics industries due to its mechanical strength, electrical insulation, thermal stability, chemical inertness, and biocompatibility. Ultrafast lasers provide the needed precise, non-contact micromachining processing technique with a minimal need for post-processing.

Results from our application lab indicate that our Onefive ORIGAMI XP femtosecond laser can be used to achieve a debris-free no-HAZ machining of polyimide film. The higher peak power of femtosecond laser pulses helps to vaporize polyimide film instantly, leaving a debris-free surface.

We have designed our ORIGAMI XP for easy and cost-effective integration. It comes in an air-cooled, single-box chassis with removable handles and offers full remote-control capabilities. With a rugged design and low maintenance costs, it is ideal for many industrial applications.
