Insulated glazing units and methods

Abstract

A hermetically sealed multi-pane window assembly comprises first and second windowpane sheets formed of transparent materials. A first sealing member has an inner edge and an outer edge, the inner edge being hermetically attached around the periphery of the first windowpane sheet by diffusion bonding. A second sealing member has an inner edge and an outer edge, the inner edge being hermetically attached around the periphery of the second windowpane sheet by diffusion bonding and the outer edge being hermetically attached to the outer edge of the first sealing member. A spacer assembly is disposed between the first and the second windowpane sheets for maintaining a gap therebetween, whereby a hermetically sealed cavity is defined between the first and the second windowpanes.

Problems solved by technology

So, an SMT reflow solder connection to the PWB of a MOEMS device that uses a lower melting point solder preform for the window may have the adverse effect of reflowing the solder of the window assembly, cracking the window into thin layers

[0010] A third disadvantage is that the solder that acts as an interlayer between the glass and the Kovar frame has a CTE that is up to three times greater than the two materials it joins

Problems include: spacers are opaque or aesthetically unappealing so they do not meet i
