TLA7AXX Logic Analyzer Module Service Manual

Inspect the internal portions of the logic analyzer module for damage and wear
using Table 6--2 as a guide. When found, defects should be repaired immediately.
If you must replace an internal component, refer to the

Removal and Installation

Procedures

, later in this chapter, for detailed removal and replacement instruc-

tions.

CAUTION.

Do not attempt to repair any circuit boards with a soldering iron.

Most of the internal components are surface mounted devices. Using a soldering
iron can damage the surface-mounted components and internal circuit boards.
Refer the replacement of surface-mounted components to qualified service
personnel with the appropriate tools.

Table 6- 2: Internal inspection check list

Item

Inspect for

Repair action

Circuit boards

Loose, broken, or corroded
connections. Burned circuit
boards. Burned, broken, or
cracked circuit-run plating.

Remove failed circuit board and
replace with a new one.

Resistors

Burned, cracked, broken, blis-
tered condition.

Remove failed circuit board and
replace with a new one.

Capacitors

Damaged or leaking cases.
Corroded solder on leads or
terminals.

Remove failed circuit board and
replace with a new one.

Semiconductors

Damaged parts or distorted pins.

Replace circuit board if parts are
damaged.

Wiring and cables

Loose plugs or connectors.
Burned, broken, or frayed wiring.

Firmly seat connectors. Repair or
replace circuit boards with defec-
tive wires or cables.

CAUTION.

To prevent damage from electrical arcing, ensure that circuit boards

and components are dry before applying power to the logic analyzer module.

To clean the interior, perform the following steps:

1.

Blow off dust with dry, low-pressure, deionized air (approximately 9 psi).

2.

Remove any remaining dust with a lint free cloth dampened in isopropyl
alcohol (75% solution) and rinse with warm deionized water. (A cotton-
tipped applicator is useful for cleaning in narrow spaces and on circuit
boards.)
