Abstract

1,259,804. Circuit assemblies. HAWKER SIDDELEY DYNAMICS Ltd. 28 Feb., 1969, No. 5008/69. Heading H1R. In an hermetically sealed circuit package including a conductive pattern on a substrate and leads extending from the package bonded to the conductive pattern a hermetic seal of insulating material such as glass, glass ceramic, inorganic or organic resin or rubber is formed over both the leads and part of the conductive pattern. A metallic, glass, glass ceramic or ceramic substrate has conductive coatings 2 screen printed thereon and then successive layers of insulating material 3, 5 and conductive material 4, 6 deposited in the required pattern. Preformed output leads 7 are then attached to the conductive areas 2 and a frame 8 metallized on one of its major plane surfaces 9 and coated with a sealing glass 10 is placed over the assembly and sealed by heating, the glass 10 seal extending over part of the circuit pattern as well as the leads 7, Fig. 2 (not shown). After affixing components to the circuit assembly sealing caps 11 of metal, glass or ceramic are sealed to the metallized areas 9. In an alternative arrangement the assembly may be coated with the glass 10 or a rubber or resin and then the frame 8 is fitted.
