COMPONENT INSTALLATION

Perform the following procedure to install the component.

NOTE

To prevent damage to the component during placement, PACE recommends
handling the component with a vacuum pick device such as the PACE Pik-
Vac or HandiPik.  Always place the hot tip in a tip holder or on a metal
surface to prevent burns or scorches.

1. Carefully clean the replacement component leads (or terminations) and

substrate land pattern area using an approved solvent.  Insure that no
leads or terminations become deformed during the process.

2. Apply solder paste to the lands.

3. Properly orient the replacement component with respect to the land

pattern; centering the component leads (or terminations) with their
corresponding lands.

4. Gently place the component

onto the land pattern taking
care to maintain proper lead to
land alignment.

5. Apply a very small downward

pressure to the component
body; forcing the leads (or
terminations) gently into the
solder paste.
