The DM2700PF is a family of low temperature glass preforms designed for
assembling and hermetically sealing small optical and electronic components.
Applications include sealing glass optical fibers in a metal package without fiber
metallization. The preforms adhere well to a wide variety of metals, glasses,
ceramics, and semiconductor materials. The preforms are pressed from a
proprietary glass powder into a wide variety of shapes and sizes and then
sintered. The sintering process provides green strength for the assembly
operation and removes all organic residue. There is no outgassing during or
after the sealing process. The DM2700PF seals at temperatures as low as
320 °C.
