Description

Technical Field

[0001] The utility model relates to the technical field of resistance testers, in particular to a heavy hammer surface resistance tester. Background Art

[0002] The heavy hammer surface resistance tester is a test device widely used in the field of electrostatic protection and electrical performance testing. This device uses a heavy hammer-shaped metal ball for testing and can quickly and accurately measure the resistance value of various surface materials.

[0003] Its principle is based on the electrostatic phenomenology theory, that is, the resistance value is caused by the electric field and potential difference formed when charges gather on the surface of the conductor. When the metal ball in the tester contacts the surface of the conductor, the static charge on the surface of the sample will form a potential difference between the ball and the sample, thereby generating current. By measuring the potential difference between the metal ball and the sample, the surface resistance value can be calculated.

[0004] In terms of electrical performance testing, many electrical components and circuit boards require specific electrical properties to ensure their reliability and stability. This equipment can be used to measure the electrical properties of these materials and quickly test these products.

[0005] However, when the existing resistance tester is in use, the wires connecting the weight electrode are easily entangled with each other, resulting in a knot in the wires that affects their use. During the test, the connector of the connecting wires may also be damaged when it is plugged into the tester.

[0006] Therefore, it is necessary to provide a heavy hammer surface resistance tester for use. Utility Model Content
