1-53. When using a soldering iron to replace
transistors, you must be sure there is no
current leakage between the power
source and the tip of the iron. Which of
the following actions should you take if
current leakage is detected?
1. Reduce the wattage of the heating
element
2. Use an isolation transformer to power
the soldering iron
3. Use a soldering gun instead of a
soldering iron
4. Isolate the soldering iron from
ground by disconnecting the
soldering iron safety ground wire
1-54. Which of the following is a description
of ESDS devices?
1. Components that are sensitive to
electrostatic discharge
2. Components that are sensitive to the
electromagnetic pulse produced by a
nuclear detonation
3. State-of-the-art devices used to detect
electronic emissions
4. Devices designed to withstand any
type of electromagnetic or
electrostatic interference
1-55. MOS and CMOS devices without input
diode protection circuitry belong in
which, if any, of the following ESDS
device categories?
1. Sensitive devices
2. Very sensitive devices
3. Moderately sensitive devices

1-56. Wearing a grounded wrist strap when
repairing electronic circuit boards serves
which of the following purposes?
1. It identifies you as being 2M
qualified
2. It protects ESDS devices from
damage
3. It protects the technician from
electrical shock
4. It protects you from rf burns when
working near radar antennas
1-57. What, if any, precaution should you take
before you open a package that contains
an ESDS device?
1. Rub the package against a dissimilar
material
2. Discharge any static electricity by
connecting a grounded lead to the
package
3. Measure the static charge on the
package with an oscilloscope to
ensure that it is within tolerance
4. None
