In order to study the influence of air gap and focus position on the quality of ps-laser glass-to-glass welding we implemented a method of detecting the air gap between glass surfaces based on optical thin film interference. The method allows real-time optimization of the welding process. We measure the air gap between glass surfaces to be bonded a...
Glass was coated with copper films of different thicknesses by the vacuum evaporation method to realize the packaging technology for circuit manufacturing directly on glass substrate. Transient temperature and stress fields during welding of copper-plated glass were calculated using the ANSYS software. Welding experiments were conducted using a nan...
In the present work, a direct bond between glass and silicon with optical contact was formed by 515 nm picosecond laser controlled by the galvanometer scanning system. A crack-free welding effect without edge breakage and residues was obtained with breaking strength as high as 122 MPa. New crystalline phase (SiO2) was produced and silicon and oxyge...
