Beam Lead Terminated Gas Discharge Panel

This process for providing connections between a gas panel and its driving source makes use of a variation of beam-lead technology, a technique used in silicon device fabrication.

In this method of panel construction, the surface of each glass plate is first coated with an organic or inorganic material, such as photoresist, potassium chloride or glass frit, that can be readily dissolved in an appropriate solvent. This coating is only deposited on the area between the score mark 3 and the end of the plate 5, as shown in the figure. The plate is then metallized and photoetched in a conventional manner with the desired pattern. At this point, the metal contact pads are plated to an appropriate thickness (approx. 0.010'') by electroless or electroplating techniques. After the plating process, the underlayer is removed by dissolving in a solvent and the glass is cracked off at the score mark 3, leaving a plurality of contacts 7 extending out from the edge of the glass which can be mated to an appropriate mechanical connector, or soldered to a mating printed-circuit board. If desired, these contacts could be bent around the edge of the glass, permitting interconnection to be made to the upper or lower side of the plate. This procedure eliminates the costly reflow soldering to flexible cable technique normally used for mechanical connection between a panel and its driving source.
