Abstract

The invention provides a special circuit board bending resistance testing machine, which relates to the field of circuit board testing. The special circuit board bending resistance testing machine comprises a supporting table and an upper frame, the lower end of the upper frame is fixedly connected with the upper surface of the supporting table, a material table is arranged between the upper frame and the supporting table, the right side face of the material table is fixedly connected with a discharging box, the bottom face of the material table is fixedly connected with four supporting telescopic rods, and the lower end of the supporting telescopic rod is fixedly connected with the upper surface of the supporting table. According to the special circuit board bending resistance testing machine, through the arrangement of the pressing plate, the cavity, the pressure spring and the inclined plate, if the circuit board is not broken, the pressing plate is U-shaped, so that the unbroken circuit board can be stably supported upwards, and if the pressing plate is pressed downwards to break the circuit board, the supporting columns cannot stably support the circuit board, the circuit boards fall on the supporting table, and the circuit boards meeting the conditions are separated from the circuit boards not meeting the conditions.

Description

technical field [0001] The invention relates to the field of circuit board testing, in particular to a special circuit board bending resistance testing machine. Background technique [0002] The names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. [0003] In some special use environments, the hardness of the circuit board material used must reach a certain strength, so that the circuit board can withstand a certain degree of bending, so it is necessary to test the bending performance of the circuit boa...
