<p>A process for manufacturing housings for hybrid integrated circuits consists in shaping a sheet metal cut-out to form the actual housing (10A), sealing in (17) feed-through pins (16) and then closing with a lid. The dimensions of the actual housing (10A), which can be manufactured without special tools, are optional. The corners of the sheet metal cut-out are notched or cut away, and the side parts (11A, -14A) so obtained are bent upward leaving a narrow gap (15) in each case, which is then closed by hard soldering; the lid is made by joining two sheet metal cut-outs, one of which is inserted in the housing (10A) and the other of which covers the latter. Even relatively deep housings (10A) can be manufactured. Cooling and fastening tabs integral with the housing are obtained by cutting away the corners of the side parts (11A, 12A).</p> |
