High heat resistance technology

Testing under high temperatures, the spring load increased due to the heat burden causing issues of not being able to maintain an appropriate load in regards to the electrode during testing.

Spring forth under high heat temperature is shown as below figures. Measuring conditions are at 200°C, 24 hours, 10 cycles. Spring load of a heat resistance spring is shown in the upper figure.
