Problems solved by technology

When repairing chip resistors in the prior art, the repairing groove 2 is usually set close to the center of the resistor body. In this way, the effective cross-sectional area of ​​the middle part of the resistor body is reduced after the resistance is repaired, resulting in slow heat dissipation of the resistor and further Resulting in lower power for chip resistors

Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In order to better highlight the present invention, the problems existing in the existing chip resistors after resistance repair are introduced in detail below:

[0031] 1. If figure 1 As shown in (b), the existing chip resistor is provided with a resistance repair groove, and the position of the resistance repair groove is set close to the middle of the resistor body. 1 / 4 of the length L of the resistor body, that is, A1≥1 / 4...

Abstract

The invention discloses a chip resistor, comprising: a first resistance repair groove and a second resistance repair groove oppositely arranged on a resistor body; a resistance repair port of the first resistance repair groove and the chip resistor The distance between the front electrode at the left end of the chip resistor is less than 1 / 8 of the length of the resistor body; the distance between the repair opening of the second resistance trimming slot and the front electrode at the right end of the chip resistor is less than 1 / 8 of the length of the resistor body . By implementing the embodiments of the present invention, the withstand power of the chip resistor can be improved.

Description

technical field [0001] The invention relates to the technical field of resistor preparation, in particular to a chip resistor and a preparation method thereof. Background technique [0002] like figure 1 As described in (a), the resistance characteristics of the existing chip resistors are mainly generated by the resistor body 1 , in order to make the resistance value of the resistor meet the preset target resistance value, the resistance of the resistor is trimmed. When repairing chip resistors in the prior art, the repairing groove 2 is usually set close to the center of the resistor body, so that the effective cross-sectional area of ​​the middle part of the resistor body is reduced after the repairing, resulting in slow heat dissipation of the resistor and further As a result, the power that the chip resistor can withstand is lower. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a chip resistor and a manufacturing method thereof, which...
