Abstract

The invention provides a test fixture for a single layer capacitor, so as to effectively solve problems that the prior fixture causes damages to a capacitor electrode and the test efficiency is low, realize undamaged test and aging on the single layer capacitor, simplify taking and placing operation during the test and aging steps of the single layer capacitor, improve the production efficiency and reduce equipment cost. The test fixture for the single layer capacitor comprises two electrode plates arranged in a mutually parallel mode, and is characterized in that probes are relatively arranged between the electrode plates respectively, the probes clamp the single layer capacitor in a vertical matching mode, and the plane contact area of probe ends of the probes is larger than the electrode area of the single layer capacitor.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a test fixture for single-layer capacitors. Background technique [0002] The upper and lower sides of the single-layer capacitor are planar gold electrodes. After the single-layer capacitor is manufactured, follow-up tests such as parameter testing, high-temperature aging, and post-aging parameter testing are required, and it is required that no pressure point traces be left on the surface of the two gold electrodes during the aging test. [0003] In addition, the size of the chip capacitor is small, and it is time-consuming and laborious to test a single single-layer capacitor alone. The relative efficiency is relatively low, and it is not suitable for mass production and the improvement of production efficiency. Therefore, it is necessary to minimize manual direct operations in mass production testing. The current production Different fixtures are used for the middle test,...
