connections. Check the entire board surface for solder splashes
and bridges.

2. Check the interboard wiring to ensure that no wires are “pinched”
or contact high-wattage resistors.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from
all exposed metal parts to any exposed metal part having a return to
chassis, must not exceed 0.5mA (500 microampers). Leakage current
can be measured by any one of three methods.

all exposed metal parts to any exposed metal part having a return to
chassis, must not exceed 0.5mA (500 microampers). Leakage current
can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
TW-540A. Follow the manufacturers’ instructions to use these
instruments.
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245 digital
multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM
or battery-operated AC volmeter. The “limit” indication is 0.75V,
so analog meters must have an accurate low voltage scale. The
Simpson 250 and Sanwa SH-63Trd are examples of a passive
VOM that is suitable. Nearly all battery operated digital multimeters
that have a 2V AC range are suitable. (See Fig. A)

Unleaded solder
Boards requiring use of unleaded solder are printed with the lead-free
mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with the
lead free mark due to their particular size.)

Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40°C highter than
• Unleaded solder melts at a temperature about 40°C highter than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to about
350°C
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!

• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.
