Laser processing of glass frit for sealing applications

摘要

Light-absorbing glass frit material is used to seal an opening in a device or a plurality of devices in a batch process. The glass frit material is applied and then irradiated with light having a wavelength absorbed by the glass frit material so that the glass frit ball undergoes a glassy transition and forms a seal. When sealing an opening in a device, the glass frit material may be applied as a spherical ball such that the spherical ball covers the opening. The volume of the spherical ball may be selected to determine the final shape of the seal.
