Instructions for Use of Test Fixture
A pair of flat-tip tweezers can be used to insert or remove a package from the test fixture. Always wear a grounding
strap to prevent ESD.
1. To insert a package, remove the four finger nuts and gently lift the pressure ring off of the test fixture.
2. Place the pressure ring, cavity side up, on a flat ESD safe surface.
3. Connect the metal tube to any general-purpose vacuum source with flexible tubing. The vacuum source should
be off.
4. Place the package, lid down, on a flat ESD safe surface. Locate pin 1 on the package.
5. Insert the package into the pressure ring (lid down) with pin 1 located next to the orientation mark and turn on
the vacuum. The vacuum will retain the package in the pressure ring during the following steps.
6. Align the vertically conductive material on the circuit board.
7. Place the pressure ring down over the alignment pins and gently tighten the finger nuts.
8. Remove vacuum, if desired. The vacuum source tubing can be removed for convenience.
