HP 5384A and HP 5385A
Installation
j. Place the transistor in the Q2 location so the
hole in the transistor heat sink aligns with the
threaded hole in the battery stop. Trim the leads on
the transistor to provide clearance between the A3
board and the battery stop.
k. Secure the heat sink temporarily to the battery
stop with a screw.
I. Solder one lead of the transistor to the A3
board.
m. Remove the A3 board and solder the remain-
ing two leads. Clip the soldered leads to avoid
shorting against the battery stop.
n. Spread heat sink compound on the back of the
transistor. Enough compound should be applied so
that when the transistor is secured to the battery stop
(step "p") a tiny amount will ooze from underneath
the transistor. Good thermal conduction will result.

o. Place the transistor insulator underneath tran-
sistor Q2: The tab fits into a slot at the edge of the A3
board. Align The hole in the insulator with the hole in
the heat sink.
p. Place the insulator washer on the heat sink,
secure Q2 to the battery stop with a screw.
q. Secure the A3 board to the battery stop with
two screws and two lock washers.
r. Attach the rubber bumper to the battery stop
in the square silk screened on the battery stop.
s. Connect the ribbon cable W2 to A3J1 and
A1J9.
t. Test and adjust the battery charger board.
Refer to Section V, paragraph 5-26, for adjustment
procedures.
u. Replace the cover on the counter, installation
is complete.
