D.7.4 General Repair Requirements.
Refer to Figures D-30, D-31, and D-32. The following general
requirements apply to the repair of MVP CCA.
CAUTION
The MVP CCA contains components subject to damage by electrostatic discharge
(ESD). Use approved grounding procedures before touching, removing, or
inserting CCA.
a. Ensure that components are properly oriented before installing.
b. Square mounting pad designates:
(1)
Pin 1 of integrated circuit
(2)
Emitter of transistor
(3)
Cathode of diode
(4)
Positive lead of capacitor
c. Do not bend leads of component U34.
d. Bond components C38, C39, C42, and C44 to printed wiring board (PWB) with MIL-A-46146, Type
Ill adhesive before applying insulation compound.
e. Use only SN63WRMAP3 tin/lead solder or approved equivalent.
Insulation compound must not be applied to any connector pins. Inadvertent
application of compound to connector pins may require replacement of connector.
f.
Apply uniform coating of MIL-I-46058 TYPE 1B31 insulation compound 0.003±0.002 in. thick,
where compound has been removed during CCA repairs.
g. Do not apply insulation compound to mounting holes on either side of PWB, and to test points TP1
through TP5.
h. Apply primer MIL-S-22473 grade T and sealing compound MIL-S-22473 grade CV to threads.
i.
Bond acceleration switch AC1 to holder using MMM-A-134 epoxy glue.
