Embodiment 2
[0107] The substrate is laser engraved with a hole / terminal, and the conductive paste is filled into the hole, and then the anode block is bonded to the substrate, and the other processes are the same as Comparative Example 2.
[0108] Effect verification example 2: Please continue to refer to Figure 13 , the effect verification example 1 of circuit design and parameters is the same, but during this verification, only 3 capacitors of comparative example 2 and 3 capacitors of embodiment 2 of this application are used to install in the line (capacitors are installed in the marked CAP in the diagram position), the peak-to-peak value of the CPU power supply terminal voltage was measured, and the data are listed in Table 2.
[0109] Data comparison:
[0110] For the target product 6.3V 220uF conductive polymer aluminum capacitor, test the ESR of the comparative product (as shown in Table 2 below):
