Description
technical field [0001] The invention relates to the technical field of capacitors, in particular to a flexible film capacitance testing system and method. Background technique [0002] As we all know, capacitors, as basic electronic components, are widely used in smart phones, tablet computers, mobile communications, computers, measuring instruments and other product equipment; and capacitors must undergo withstand voltage tests before leaving the factory to screen out unqualified products . Flexible film capacitors are a type of capacitor. Flexible film capacitors are a flat capacitor structure. The medium between the upper and lower flat electrodes is a flexible thin film capacitor. According to the characteristics of the capacitor structure, the formula for calculating the capacitance value C of the flexible thin film flat plate is as follows: [0003] [0004] Among them, C is the capacitance value of the flexible film capacitor; A is the area facing the upper and lo...
