Abstract

The invention discloses a resistance plate. The resistance plate comprises an insulated substrate, a conductor layer and a resistor layer, wherein the conductor layer and the resistor layer are arranged on the insulated substrate respectively; the conductor layer and the resistor layer are partially overlaid, the resistor layer is covered on the partial surface of the conductor layer in an overlapped area of the conductor layer and the resistor layer, a moisture-proof layer and a resin protective layer are sequentially formed on the resistor layer, and an anti-corrosion wearing layer is formed on the conductor layer in an area where the conductor layer is not overlapped with the resistor layer. According to the resistance plate, the moisture-proof layer and the resin protective layer dual-layer protection process is adopted to improve the moisture resistance and the corrosion resistance of the resistor layer, the corrosion resistance and the durability of the conductor layer are improved through the anti-corrosion wearing layer, so that the resistance plate can effectively work in a complex working environment for a long time when being applied to a fuel quantity sensor, and has good durability. The invention also discloses a preparation method of the resistance plate.

Description

technical field

[0001] The invention relates to a resistance plate and a preparation method thereof. Background technique

[0002] The resistance plate is an important component of the sensor. The conductors and resistors of the resistance plate used in traditional oil level sensors are formed by printing and sintering with electronic paste. The performance of the product depends on the characteristics of the electronic paste itself.

[0003] Since the resistance plate for oil quantity sensor works for a long time in an environment rich in corrosive chemical components such as water, alcohol, organic acid, sulfur compound, fluorine, etc., resistance and conductor corrosion are very easy to occur, resulting in the durability of the resistance plate for oil quantity sensor. Sex is poor. Contents of the invention

[0004] Based on this, it is necessary to provide a resistance plate with better durability and a preparation method thereof.

[0005] A resistance plate, compris...
