Problems solved by technology

[0002] The production method of the LED display module in the prior art is to directly point the crystal glue on the support, and then perform processes such as wire bonding and glue injection. After all the processes are completed, the drying process is carried out again. Drying processes such as dehumidification and baking are only carried out after the production is completed, which will cause moisture to be sealed between the chip and the PCB after the glue is injected. During the power-on test process, it is easy to cause a short circuit, and the product is safe and reliable. Sex is not high

Embodiment Construction

[0019] A method for producing an LED display module. The display module includes a bracket module array. The bracket module array includes an insulating bracket and a PCB board sealed in the insulating bracket. The PCB board is provided with four electrodes and four The four pins electrically connected to the block electrode, the production method of the LED display module is as follows:

[0020] (1) Dehumidification of the bracket module array: put the bracket module array in an environment of 160±5°C and bake for 1.5-2.5h. After the dehumidification is completed, store the bracket module array in a 60±5°C oven or a moisture-proof cabinet Standby, in this embodiment, the baking temperature of the bracket module array is 160° C., and the baking time is 2 hours.

[0021] (2) Solid crystal: After taking out the bracket module array from the oven or moisture-proof cabinet, complete the solid crystal within 4.5 hours, and then bake it in an environment of 160±5°C for 1.5-2.5 hours...

Abstract

The invention discloses a manufacturing method of an LED display screen module. The manufacturing method comprises the following steps: carrying out dehumidifying on a bracket module array, carrying out wafer bonding, carrying out wire soldering, carrying out dispensing, carrying out cooling, carrying out light splitting, carrying out dehumidifying before braiding, carrying out braiding, carrying out dehumidifying after braiding, etc. According to the manufacturing method, the manufacture technology of the LED display screen module is optimized, the links of baking dehumidifying, drying preservation and the like are increased in each step, and therefore, the production efficiency and the product quality are effectively improved.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a production method of an LED display screen module. Background technique [0002] The production method of the LED display module in the prior art is to directly point the crystal glue on the support, and then perform processes such as wire bonding and glue injection. After all the processes are completed, the drying process is carried out again. Drying processes such as dehumidification and baking are only carried out after the production is completed, which will cause moisture to be sealed between the chip and the PCB after the glue is injected. During the power-on test process, it is easy to cause a short circuit, and the product is safe and reliable. Sex is not high. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a method for producing LED display screen modules that effectively improves production efficiency and p...
