2.7. Thermal Shock
No evidence of physical damage was visible as a result of thermal shock testing.
2.8. Humidity/temperature Cycling
No evidence of physical damage was visible as a result of humidity/temperature cycling.
3. TEST METHODS
3.1. Examination of Product
Specimens were visually examined for evidence of physical damage detrimental to product
performance.
3.2. Insulation Resistance
Insulation resistance was measured between adjacent contacts of unmated specimens. A test voltage
of 500 volts DC was applied for 2 minutes before the resistance was measured.
3.3. Withstanding Voltage
A test potential of 1000 volts AC was applied between adjacent contacts of unmated specimens. This
potential was applied for 1 minute and then returned to zero.
3.4. Solderability
Contact solder tails were immersed in a non-activated rosin flux for 5 to 10 seconds, allowed to drain for
10 to 60 seconds and then held over molten Sn60/Pb40 solder maintained at 245°C without contact for
2 seconds. The contact solder tails were then immersed in the molten solder at a maximum rate of 1
inch per second, held in the molten solder for 3 to 5 seconds and then withdrawn at a maximum rate of
1 inch per second. Specimens were cleaned using isopropyl alcohol and then visually examined for
solder coverage.
3.5. Component Resistance to Wave Soldering
Specimens were placed on .061 inch thick printed circuit board and the solderable areas of the
specimens immersed in non-activated rosin flux type ROL0 maintained at room temperature for 5 to 10
seconds, removed from the flux, and allowed to drain for 5 to 20 seconds. The specimens were
attached to a dipping machine and immersed at a rate of approximately 1 inch per second into a
Sn60/Pb40 solder bath maintained at 240 ± 5°C to a point where the component body was 1 to 2 mm
above the solder surface, held in the solder bath for 10 seconds, and then removed at a rate of
approximately 1 inch per second. Specimens were cleaned for 5 minutes using isopropyl alcohol and
then given a visual examination under 30X magnification.
