Description
Technical Field
The utility model relates to a test equipment field especially relates to a flexure test mechanism.
Background
With the trend of miniaturization and miniaturization of communication and electronic equipment, copper foils and various materials also tend to be thinner, and the thickness requirement is thinner and thinner, and the circuits are smaller and denser. With the further improvement of the requirements, the performance requirements of many materials are changed, and many material parameters which are not included and paid attention to in the past are gradually and more concerned. However, corresponding standards and detection means are not kept up with the above-mentioned method, so that performance tests required by many materials are completed in a compact manner, time and labor are consumed, and the actual performance of the materials cannot be truly reflected by the test process and the results.
Copper foil and copper-clad flexible material, printed circuit board, etc. (hereinafter, collectively referred to as "copper foil material") in the range of 9um to 200um (approximately) are increasingly used in the electronic industry, and the usage factors thereof have been shifted to the flexibility and bendability of the copper foil material (applications such as flip phones, portable computers, mobile phone retractable lenses, printed circuit board cables, etc.). These applications require, without exception, that the copper foil material must have good flex resistance, especially in confined spaces. According to partial data, the bending and flexing resistant times of the copper foil material when the bending radius is 0.5mm-2.0mm need to be more than 10 ten thousand times. Based on the above, in the performance test of the copper foil material (especially, the copper foil used as the circuit substrate), the resistance change and the final bending resistance frequency in the micro-radius bending process need to be tested, and the bending resistance of the copper foil material has become an important index for evaluating the copper foil material, and is increasingly paid attention by various suppliers and manufacturers.
The current industry test for small radius flex resistance of copper foil material is generally as follows in figure 1: the shadow part is a test material (H is the thickness of the material), the A end of the shadow part is a fixed end (both in a pasting or clamping way), the B end is a sliding end, the bending radius formed between the A end and the B end is the bending radius, and the up-and-down sliding distance of the B end is the bending stroke. In the bending resistance test of the product, the material is bent at the end B according to a fixed frequency and a fixed stroke, and then the bending resistance of the copper foil material can be obtained by detecting the resistance value of the material after different bending times, wherein one-time test is usually within 4 hours to 3 days according to the requirement.
At present, no standard operation specification and equipment exist in the industry, and the moving end B moves back and forth by adopting machinery or even hands, and after the moving end B bends for a certain number of times, a universal meter or other instruments are used for measuring the resistance value manually. The whole test process is time-consuming and labor-consuming, and due to the lack of necessary mechanical means for assistance, the number of simultaneously measurable samples is usually only one to a few, so that the whole deflection test process is not only slow in efficiency and poor in resistance test precision, but also the test result usually cannot accurately represent the actual performance of the material.
