The frit laser sealing process has been modeled through the finite element method. Transient thermal stress results have been used to explain experimental observations, and to provide further processing recommendations and design guidelines. The results explained why high CTE glass is hard to seal. A simple and practical solution is demonstrated to reduce the transient thermal stress by elevating ambient temperature during high CTE glass sealing.
