Reply compression test mode
A. Measuring the thickness of the sample
B. at a temperature of 70 ˚ C ± 1 ˚ C of the state, the compression test sample to 50%, sequential compression 22 hours
C. After 22 hours the compression, left to stand at room temperature for 30 minutes and then measure the thickness of the sample
C = {1 - [t0-t1 / t0]} x 100
t0 = Thickness (Before)-mm
t1 = Thickness (After)-mm

Tensile testing
The SMT Gasket way to lead-free solder adhesive on the printed circuit board.
The circuit board fixed the speed of 50mm per minute forces, by the side.  SMT Gasket to produce thrust.
In SMT Gasket completely separated from the printed circuit board, to calculate the pull Force value.
