Problems solved by technology

Accordingly, there is a high possibility that high voltage due to ESD will be applied to the internal main circuit including the signal ground (which is different from the frame ground) as the circuit ground
Therefore, operation errors, interruption of operation, damage, etc. due to ESD are likely to occur
[0017] In addition, in addition to USB devices, in portable devices such as memory cards, there are also cases where the entire casing is made of molded resin such as polycarbonate, and in these cases, there is also a possibility that ESD may damage the inside. The hidden danger of the influence of the circuit
