Abstract

The invention is applicable to the field of electronic device manufacturing, and provides a low-temperature drift high-power resistor and a preparation method thereof. The resistor includes: two pins, a substrate, a two-pin conductor formed on the substrate, and a first conductor formed on the substrate. A sub-resistor; the first sub-resistor is rectangular, and its two short sides are respectively connected to the two-pin conductors, and the first sub-resistor is completely covered in the first resistance region by a resistor paste film with a first thickness and has a second thickness The resistive paste film is partially superimposed and covered on the resistive paste film with a first thickness; the pins are correspondingly connected to the pin conductors by dipping tin. The present invention adjusts the thickness of the resistance printing film layer by improving the thick film printing process, and improves the temperature characteristics of the resistance in the full temperature range (-55°C to 125°C) through the proportion of different film thickness regions, so that the temperature characteristics of the resistance are far smaller than There are existing products in the market with a wide range of temperature applications, which can meet the requirements of users for installation and use.

Description

Technical field [0001] The invention belongs to the field of electronic device manufacturing, and particularly relates to a low-temperature drift high-power resistor and a preparation method thereof. Background technique [0002] With the rapid development of the electronics industry, various electronic devices are becoming more and more precise in design, which enables products to work stably and accurately in various environments, and there are higher and higher requirements for the temperature characteristics of electronic components. . [0003] As a common electronic component, resistors are widely used in various electronic devices. Different types of resistors can be selected for different circuits, usually in the full temperature range (-55℃~125℃) or high voltage (3000V). High-power and high-voltage resistors. The temperature characteristics of existing high-power and high-voltage resistors in the full temperature range (-55℃~125℃) are basically greater than ±100ppm / ℃, whic...
