Seal Installation using solder fixture:
A. Center fixture and locate solder preform.
  1. Bottom centering tool in fixture housing with small end protruding beyond fixture base.
  2. Install preform around centering tool protrusion.
  3. Hold fixture and preform upright. Align centering tool protrusion with seal counter bore in panel.
  4. Secure fixture to panel with 2 mounting screws. The preform should be properly centered in the solder groove.
B. Seal Installation using solder fixture.
  1. With preform located and fixture securely mounted. Remove centering tool.
  2. Position seal center conductor onto tool with connector end in.
  3. Reinstall centering tool, hand tighten to bottom seal in panel.
  4. Apply heat to flow solder.
  5. Remove fixture.
  6. Clean.
  7. Install connector.

Note: Other soldering techniques may be utilized. Other methods should still achieve proper seal center conductor centering and position seal front surface orthogonal to connector axis to provide 360° of outer conductor contact for effective microwave performance.
