In the case of resin, resin temperature is about 300 ℃, mold temperature is about 130
The porous separator inside the element, which is exposed to the conditions of ℃ and molding cycle time of about 2 minutes, becomes thin near the sidewall of the non-conductive gasket due to heat and pressure, and further cracks occur, causing electrical characteristics failure as a capacitor. There was a quality problem such as reaching.
