Polymer Welding

Capabilities of ultrasonic welding, low temperature thermal bonding, laser transmission welding, and solvent assisted joining have been developed for the direct joining of polymers. With the developed direct polymer joining techniques, such as laser transmission welding or solvent assisted joining for transparent thermoplastics, high precision bonding can be achieved for the substrates with feature size of 50μm, and the developed technique has been successfully applied to the fabrication of polymer microfluidic devices.
