Glass in Electronics

While glass has many applications in the electronics means of "chemical machining" of photosensitive glasses. The field, five classifications serve to cover them all. The wide range of latter approach is widely applied to the making of printed wiring applications which exist is attributable to the wide range of properties boards. which can be obtained in glasses. Historically, the use of glass for its dielectric properties dates Sealability and impermeability of glasses have enabled them to back 200 years. The material is presently finding acceptance in maintain prominence in use for enclosures, starting with Edison\´s laminated capacitors where the end use demands utmost reliability. lamps and carrying through to today\´s electrostatic printing tubes. Glasses which can be sealed into laminated structures, then One recent sealing achievement was the simplification of color devitrified so as to develop ferroelectric properties, are now receiving television picture tube assembly by use of a relatively new material, attention. Devitrifying solder glass. Glass fibers as small as 8 microns in diameter are utilized in Structural and supporting parts may be made in intricate and various electronic and optical devices; cathode-ray tube trace complex shapes by means of the "multiform" process and by widths as small as 0.001 inch are obtainable by use of fibers in the tube faceplates. Bundles of fibers have been made to serve as signal pickoffs in certain ultrasonic delay line systems which take advantage of both the optical properties and some unusual acoustical properties of glass.
