The film is applied as an ink that consists of silver neodecanoate in xylene. The ink-like mixture is deposited in matching pattern on two pieces of flat glass. The pattern on the lower glass is a slightly wider line than the line on the upper glass. The glass pieces are heated in air to 260 deg. C to evaporate the xylene and decompose the silver neodecanoate, leaving adherent patterns on the glass pieces.
Solder paste is deposited on the wider line and air dried.
The upper glass is placed over the lower glass with its silver metal pattern resting on the solder paste. The glass pieces are clamped together and soldered using the standard thermal cycle specified for the solder. If the seal location requires minimum heating, the heat for decomposition and the soldering can be supplied by a well-controlled laser beam, which will confine the high temperatures to the sealing region. The filler material should flow readily over both metal surfaces and securely bond to each metal. Molten filler material has the capacity to alloy with a base metal.
