Method for preparing leads type high voltage precision ceramics capacitor

Abstract

The invention relates to a making method of a lead wire type accurate ceramic capacitor with high-pressure, which comprises the process of regulating the capacitance value, the regulating process of the capacitance value comprises the following steps: measuring the capacitance value of each ceramic sheet, if the capacitance value is larger than a set capacitance value, removing a part of metal electrodes, and then repeating the process of regulating the capacitance value until measuring the capacitance value in the error range of the set capacitance value, thereby the making method of the lead wire type accurate ceramic capacitor with high-pressure can gain the accuracy of the capacitance value of the ceramic capacitor, such as requirements of the capacitor with high accuracy of +-1% can be satisfied, and the accurate capacitive reactance value for the design of the circuit can be provided, and the making method can effectively improve the yield of products, can avoid the waste of materials and can reduce the cost of the products.

Description

technical field [0001] The invention relates to a method for manufacturing a lead-type high-voltage precision ceramic capacitor, in particular to a method for manufacturing a lead-type high-voltage precision ceramic capacitor including a capacitance value adjustment step. Background technique [0002] When you open the casing of an electronic product, you will generally see the circuit board first, which is filled with various electronic components, including active components and passive components. Active components generally refer to transistors and integrated circuits. An integrated circuit is a combination of many transistors and has the function of signal amplification. In contrast, passive components generally refer to resistors, capacitors and inductors. [0003] A capacitor is an energy storage element whose function is to temporarily store electrical energy in a circuit, and it stores energy in the form of charge. In electrical circuits, capacitors are commonly u...

Problems solved by technology

[0007] The existing leaded ceramic capacitor production method is not easy to grasp the precision of the capacitor. Generally, the best error value is ±5%. If it is required to be less than ±5%, it is often necessary to use the sorting method after the capacitor is manufactured. Select capacitors that meet the specifications, so the delivery time of the product is not easy to control, and it is easy to cause waste of materials, making it difficult to reduce product costs
