Abstract
The invention provides a graphite film four-probe resistance testing meter. The graphite film four-probe resistance testing meter is formed by a pedestal (1), columns (2), a detection assembly (3), and an elevating assembly (4), wherein the two columns (2) are symmetrically and fixedly arranged at the left side above the pedestal (1); the detection assembly (3) is fixedly arranged between the two columns (2); the elevating assembly (4) is fixedly arranged between the two columns (2), and is arranged right above the detection assembly (3); the lower part of the elevating assembly (4)is fixedly connected with the detection assembly (3) ; and the detection assembly (3) can move up and down along the two columns (2). As a spring is arranged between a pull bar and an extend arm, the graphite film four-probe resistance testing meter can maximumly guarantee that the graphite film is not damaged during the detection process; and at the same time, as the spring is provided with certain elasticity, the pressure of the spring can be adjusted and compressed by means of adjustment of a nut when the spring is compressed and fixed.
Description
Technical field
The present invention relates to graphite film processing detection technique field, particularly relate to a kind of four point probe apparatus of resistance of measuring for graphite film resistor.
Background technology
Graphite film is a kind of brand-new heat conduction and heat radiation material, and graphite film includes heat superconducting graphite composition, the usefulness of super-high heat-conductive, and graphite film is under hot environment, to adopt advanced platform to become technique, chemical method to prolong the sheet material of pressing the high-crystallinity forming. The maximum advantage of graphite guide hotting mask is, can be along membrane plane direction soaking heat radiation, compared with traditional metal material, its pyroconductivity be copper and aluminium 3-5 doubly. Fast heat point source is converted to the chemical stability that plane heat source is higher, the thermal conductivity of good anti-corrosion heat-resisting quantity excellence, electric conductivity low thermal resistance along film to soaking heat conduction. Graphite flake application smart mobile phone, FPD, notebook computer, computer peripheral device. The resistance value of graphite film is as an important parameter of the end product quality of judgement graphite film, in graphite film production process due to aspect the total quality impact of the operations such as cutting, extension on graphite film several, therefore before finally dispatching from the factory, graphite film needs the mensuration that its resistance value is correlated with, detecting instrument in the past mainly adopts manual mode to measure, because hand dipping is time-consuming, and the problem such as the degree of accuracy is not high, affect the resistance measurement of graphite film.
Summary of the invention
According to the problems referred to above, the object of the present invention is to provide a kind of graphite film four point probe apparatus of resistance, by the fixed mechanism with damping and semi-girder probe, graphite film is carried out the Fast Measurement of resistance value, improve speed and precision than traditional-handwork measurement.
