Precision application of femtosecond laser in micromachining of PDMS films

PDMS film refers to Polydimethylsiloxane (PDMS) film.PDMS is an inorganic silicon-based polymer, also known as silicone rubber.PDMS films are usually flexible, transparent, chemically inert, and have good mechanical properties, and therefore have a wide range of applications in many fields.

PDMS films are commonly used in microfluidic chips, biomedical devices, microsensors, microfluidic systems, and flexible electronics. In these applications, PDMS membranes are often used as substrates or isolation layers with good flexibility and chemical stability, and can be used to accommodate biomaterials, build microstructures, or as protective layers for sensors.

Femtosecond laser equipment can be used to process on PDMS membranes. Since PDMS membranes are soft, transparent, and chemically inert materials, femtosecond lasers typically offer the following advantages when processing on their surfaces:

Femtosecond lasers have extremely high spatial resolution and fine processing capability, which enables micro-scale processing on the surface of PDMS membranes, such as micro-holes and micro-channels. The ultra-short pulse duration of femtosecond lasers means that the heat-affected area generated during processing is very small, so thermal damage and deformation of PDMS membranes can be minimised. Femtosecond laser processing typically produces no significant melting or scorching, so the surface quality and mechanical properties of the PDMS membrane can be maintained.

Ltd. is headquartered in Guangming District, Shenzhen, China. The company is dedicated to the research and application of femtosecond laser micromachining technology, including femtosecond laser equipment development, production, sales and OEM business. On PDMS film, femtosecond laser can perform micro-processing, such as micro-hole drilling, micro-channel cutting, micro-structure etching and so on. These processing can be applied to microfluidic chips, micro biomedical devices, microfluidic systems and other fields to achieve the preparation of micro-structures and functional realisation.
