  
Seal and Encapsulation Methods
(1) HERMETIC – SEAM SEAL
PROS: hermetic, low temperature, large seal area, low profile, minimal floor space requirements
CONS: low throughput
ISSUES: dry box environment, electrode design, lid design, substrate size
(2) NON-HERMETIC – GLOB TOP
PROS: flexible, low temperature, low stress, low profile
CONS: non-hermetic, limited protection, spread, wire wash potential
ISSUES: dispensing parameters, viscosity, dams, cure
With this variety of die assembly options from which to choose it is useful to seek expert advise when designing for reliability. The technical staff at DD & S is available for consultation on such issues. Such consultation is a special service beyond the basic cost of the die or wafers and is quoted as a separate item upon request.
