Problems solved by technology

[0002] Solder paste printing stencil cleaning is a meticulous job, and operators without experience and patience cannot clean it. Usually, the staff cleans it directly with detergent, then rinses it with water, and finally wipes it dry with a cloth. This cleaning method Often lead to solder paste residue in the holes of the solder paste printing screen, low cleaning efficiency and poor cleaning quality

Embodiment

[0018] Embodiment: A method for cleaning a solder paste printing screen based on infrared high-temperature radiation, comprising the following steps:

[0019] Step 1: Use a squeegee to shave the solder paste printing screen, shave at least 3 times, and keep the same shaving direction each time;

[0020] Step 2: Put the shaved solder paste printing screen into the reflow oven for high-temperature cleaning and low-temperature solidification;

[0021] Step 3: Place the solder paste printing screen after the reflow oven is completed into the infrared high-temperature baking machine for infrared high-temperature radiation cleaning;

[0022] Step 4: Take the solder paste printing stencil cleaned by infrared high-temperature radiation out of the baking machine, cool it naturally and store it in a sealed packaging bag.

[0023] The scraper described in step one is a soft rubber scraper.

[0024] The reflow oven described in step 2 includes a heating zone, a constant temperature zone...

Abstract

The invention discloses a tin paste printing screen plate cleaning method based on infrared high-temperature radiation. The method comprises the following steps: (1) a scraper is used for scraping a tin paste printing screen plate by at least 3 times; and the same scraping direction is kept in each scraping; (2) the scraped tin paste printing screen plate is put in a reflow welding furnace for high-temperature cleaning and low-temperature condensation; (3) the tin paste printing screen plate is put in an infrared high-temperature roaster for infrared high-temperature radiation cleaning after the operation in the reflow welding furnace; and (4) the tin paste printing screen plate is taken out from the roaster for natural cooling after the infrared high-temperature radiation cleaning, and is put in a seal packing bag for storage. The method can improve the cleaning efficiency, guarantees the cleaning quality, and prevents the use of cleaning agents.

Description

technical field [0001] The invention relates to a method for cleaning a printing screen, in particular to a method for cleaning a solder paste printing screen based on infrared high-temperature radiation. Background technique [0002] Solder paste printing stencil cleaning is a meticulous job, and operators without experience and patience cannot clean it. Usually, the staff cleans it directly with detergent, then rinses it with water, and finally wipes it dry with a cloth. This cleaning method It often leads to solder paste residue in the holes of the solder paste printing screen, low cleaning efficiency and poor cleaning quality. [0003] In view of the above-mentioned defects, the designers are actively researching and innovating in order to create a method for cleaning solder paste printing screens based on infrared high-temperature radiation, so that it has more industrial value. Contents of the invention [0004] In order to solve the above-mentioned technical proble...
