Note that the four capacitor chip areas (4') (0) (c)
If you replace each block (b) and (c) - (in), each block will not have the same shape, so the printing pressure will be slightly different between the blocks, resulting in variations in capacity. Easy to occur. If the patterns are matched as shown in Figure 1, 1
Since each unit undergoes the same process, variations in capacitance are minimal. However, a large amount of waste C-D-D' occurs, resulting in a loss. Here, we are explaining the case of four sides, but if the number of hands becomes larger or the patterns become more complicated, this problem becomes difficult to solve, and in the end, you end up making a lot of waste.

Broken IIC without cutting along the two cutting lines C'-D'
By simply cutting along one cutting line -D, the respective electrodes can be exposed on the end faces of both capacitor chips, thereby making it possible to eliminate waste material and obtain a new small-capacity capacitor. In addition, by connecting parts of the electrodes that are cut and exposed on the chip end face by leaving them in the adjacent capacitor chip area using conductive paste or vapor deposition, the adhesion strength of the relay terminals can be improved, and the adhesion strength of the relay terminals can be improved. The adhesive strength of the capacitor terminal is significantly improved compared to the conventional method by connecting a part of the electrode that is left in the area and exposed on the chip end face with the necessary electrode in the capacitor chip area using conductive paste or vapor deposition. It is something that can be done.
