5. Test Method
5.1 Contact resistance variation (CRV)
5.2 Temperature coefficient of resistance
5.3 Permitted force of Driver plate
5.4 Soldering strength
Contact resistance variation should be measured with the measuring circuit shown below, or its equivalent.
The operating wiper should be rotated in both directions through 90% of the actual effective electrical travel
for a total of 6 cycles. The rate of rotation of the operating wiper should be such that the wiper completes
1 count in determining whether or not a contact resistance variation is observed at least twice in the same
location.
The trimmer potentiometer should be subjected to
each of the following temperatures (see Table 1)
for 30 to 45 minutes. The resistance value
should be measured in the chamber.
A static load of 4.9N
second. The load should be applied on driver plate uniformly by the 3mm-size plate of push-pull gage.
The trimmer potentiometer should be soldered under the soldering condition described in paragraph 7.2(1) on
standard land pattern described in 9. Outline dimensions. A static load of 9.8N
from rear side through the hole opened in the center of PCB by the 1.0±0.1mm dia. stick for 5 second.
The tests and measurements should be conducted under the condition of 15 to 35°C of temperature,
25 to 75% of relative humidity and 86 to 106 kpa of atmospheric pressure unless otherwise specified.
If questionable results occur that have been measured in accordance with the above mentioned
conditions, the tests and measurements should be conducted under the condition of 25±2°C of
temperature and, 45 to 55% of relative humidity and 86 to 106 kpa of atmospheric pressure.
When the trimmer potentiometer is tested after soldering on PCB, it should be tested after being kept
in a room (15 to 35°C, 25 to 75%RH) over 24 hours except ” 5.12 Resistance to soldering heat“.
