1.
Using Tweezers, place the beveled corner of the replacement IC against the index spring.

Figure 3-1.
CAUTION
Do not damage the spring with the beveled corner. Shorting of the two corner contacts could reuslt.
2.
Arrange the other IC corners, with the tweezers, to fit evenly at the edges of the socket.
3.
Set the cover flat on the IC with its ends properly aligned with the mating recesses in the socket. (the
cover is not symmetrical.)

How to Replace Amplifier Hybrid Circuits
The Hypcon (HYbrid-Printed CONnector) connector is designed to provide low-loss electrical and thermally
efficient connection between the printed circuit board and hybrid integrated circuit. Figure 3-2 shows an
exploded view of the Hypcon connector and gives Disassembly and Replacement instructions. When replacing
the hybrid ICs be careful not to touch the elastomer gold-plated contacts with your fingers, or to use a cleaner
which will degrade contact reliability. The Hypcon connector and hybrid IC should be removed if it becomes
necessary to use a cleaning solvent near the connector when replacing adjacent (within 1/2") circuit board
components.
