Embodiment Construction
[0010] In the scheme of the present invention, two insulation resistance test fixtures are fixed on a workbench, and the minimum opening distance is controlled by one screw to prevent the product chip from being damaged due to excessive force; a discharge device is installed under the workbench , the discharge device is composed of a discharge electrode column, a fixing screw, a tightening spring and a current-limiting resistor. Depending on the tension of the spring, it is ensured that the electrode column is in good contact with the terminal electrode of the capacitor; at the same time, in order to prevent damage to the electrode at the opposite end, the electrode column adopts a bearing design.
[0011] see figure 1 , the structural schematic diagram of the chip capacitor measuring discharge device of the present invention, specifically including a tempered glass operating table (1), two discharge electrodes (4) and a current-limiting resistor (5), wherein the tempered glas...

The invention provides a discharge device for electrical performance measurement of a chip capacitor and relates to the technical field of manufacturing of electronic devices. The discharge device comprises a tempered glass operating table (1), two discharge electrodes (4) and a current limiting resistor (5). The tempered glass operating table (1) is hollowed-out to enable the discharge electrodes (4) to be exposed, and a clamp for measurement is fixed to the surface of the tempered glass operating table and connected with a measuring device through a signal line. The two discharge electrodes are fixed to the back of the tempered glass operating table through screws and extend out of the middle hollow of the operating table. The two discharge electrodes are welded to two ends of the current limiting resistor respectively to form a serial connection structure. The discharge device for electrical performance measurement of the chip capacitor can effectively guarantee completeness in discharge of the chip capacitor, and accordingly product quality can be guaranteed and operating efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of manufacturing electronic components, in particular to a discharge device for measuring the electrical properties of a chip capacitor. Background technique [0002] Insulation resistance and dielectric withstand voltage are important performance indicators of capacitors, especially chip multilayer ceramic capacitors. For chip ceramic capacitors, after the voltage is applied to both ends of the capacitor, the capacitor will be charged. If there is no discharge treatment, when the two ends of two different capacitors with opposite charges are in contact, due to the instantaneous Excessive current causes sparking (electric spark), which seriously affects product appearance and product reliability. The current discharge method generally uses discharge clips to discharge one by one. While the production efficiency is low, there is also the problem of insufficient product discharge. How to improve efficiency an...
