Abstract

The invention discloses a patch glue coating device and a coating method. The patch glue coating device comprises a glue coating table, a roller-shaped net board, a scraper, an external pressurizing device, a first driving device and a second driving device, wherein the glue coating table is used for supporting a base plate to be coated; a plurality of hollow meshes which are corresponding to a preset coating area of the base plate to be coated are formed on the roller-shaped net board; the scraper is positioned in the roller-shaped net board; the external pressurizing device is used for pressurizing patch glue; the first driving device is used for driving the roller-shaped net board so as to ensure that the roller-shaped net board rotates above the surface of the base plate to be coated around the center of the base plate to be coated; and the second driving device is used for driving the base plate to be coated so as to ensure that the base plate to be coated horizontally moves on the surface of the base table.

Description

technical field [0001] The invention relates to a patch glue coating device and a coating method, more specifically, the present invention relates to a patch glue coating device and a coating method which improve the patch glue coating efficiency. Background technique [0002] SMT glue is widely used in the field of semiconductor packaging to fix chips. At present, there are two main methods for applying patch glue, one is the dispensing method, and the other is the printing method. [0003] figure 1 A prior art dispensing method for applying patch adhesive is shown. refer to figure 1 , the dispensing method of applying patch glue in the prior art includes the following steps: providing a glue coating platform 101 for providing support for the subsequent coating process; placing the substrate 105 to be coated on the glue coating platform 101, wherein, The substrate 105 to be coated has a predetermined coating area; the adhesive 104 is dropped on the predetermined coating...
