Embodiment 1

[0047] see figure 1 , figure 1 It is a flow chart of the screen printing method 100 provided in the first embodiment. The screen printing method 100 is mainly used in the production of chip resistors, and is a printing method that has the advantages of flexible and diverse printing methods, large printing area, and is not limited by the size and shape of the substrate. The screen printing method 100 provided in this embodiment can produce products with good consistency in resistance value and high pass rate of product appearance.

[0048] The steps of screen printing method 100 include:

[0049] In step S110, a screen printing plate is made by using a mask plate with a plurality of dumbbell-shaped figures and a screen.

[0050] see figure 2 , figure 2 Shown is a schematic diagram of the dumbbell-shaped mask plate 20 provided by Embodiment 1 of the present invention. The dumbbell-shaped mask 20 has a dumbbell-shaped body in a rectangular shape and four corners in a smal...

Embodiment 2

[0075] see Figure 5 , Figure 5 Shown is a three-dimensional schematic diagram of the resistor 10 provided by Embodiment 2 of the present invention. The resistor 10 is approximately in the shape of a cuboid, and is manufactured by the provided screen printing method 100 using the embodiment.

Abstract

The invention provides a screen printing method and a resistor, which relate to the field of patch resistors. A screen printing method comprises the steps of placing a substrate under a screen printing plate, wherein the screen printing plate is made of a mask plate having a plurality of dumbbell-shaped patterns, introducing a slurry into the screen printing plate, scraping the slurry so that theslurry passes through the screen printing plate and is squeezed to the substrate. By using the screen printing method, the resistor with good consistency of resistance value and high qualified rate ofproduct appearance can be obtained.

Description

technical field [0001] The invention relates to the field of chip resistors, in particular to a screen printing method and a resistor. Background technique [0002] Chip resistors have the advantages of small size, light weight, high reliability, can greatly save circuit space costs and make the design more refined, so they are widely used in high-end computers, automatic control equipment, communication equipment and multimedia electronic equipment and other fields. SMD resistors are usually prepared by screen printing at present, and the products produced by the existing screen printing methods are prone to poor consistency of resistance value and low pass rate of product appearance. Contents of the invention [0003] One of the objects of the present invention is to provide a screen printing method, which can obtain resistors with good consistency of resistance value and high yield of product appearance. [0004] Another object of the present invention is to provide a ...
