The present invention relates to a surface resistance measuring device, and more particularly, it is possible to simultaneously measure a plurality of mobile phone cases with a resistance measuring device for confirming whether an electromagnetic interference blocking agent is correctly applied to the surface of a mobile phone case in an appropriate amount. It is possible to measure the same position, and to accurately measure the resistance measurement and resistance measurement data to reflect the occurrence of defects in the electromagnetic wave blocking agent coating process relates to the surface resistance measuring device of the mobile phone case capable of preventing the same failure.

In general, electromagnetic interference refers to a noise generated from a device, which affects peripheral devices. Unnecessary electromagnetic waves are emitted through a power line or a space to interfere with reception of mobile phones, radios, and televisions.

Therefore, as the frequency domain increases, the radiation of high frequency signals gradually increases, and as the devices become smaller, the mutual coupling between components increases, and the information processing system itself is caused by momentary strong electromagnetic pulses such as malfunction or lightning of the device caused by external interference electromagnetic waves. The risk of destruction is increasing. In other words, as the information society is established, the environment related to electromagnetic waves is deteriorating.

In order to suppress such electromagnetic interference, EMC (Electromagnetic Compatibility) method should be changed according to the problem situation and various EMC measures such as grounding, shielding, and wiring should be used. Must be used in combination.

In case of mobile phone case, there is a limit to blocking electromagnetic interference by grounding or wiring, so shielding is mainly used. As a shielding method, a method of spraying or depositing electromagnetic interference blocking agent is used.
