How to maintain soldering tips of automatic soldering robot?

1. Use sponge to clean the soldering head before soldering. If the tinned part of the soldering iron head contains black oxide, a new tin layer can be plated, and then the soldering iron head can be wiped clean with a wet cleaning sponge. Repeat the cleaning until the oxide is completely removed, and then apply a new tin layer. And regularly clean the iron head.

2. When using the soldering tip for the first time, make sure to adjust the temperature of the soldering tip to 220 ℃, and let the tin part of the tip fully eat tin. It's better to soak it in the tin pile for 5 minutes, then scrub it on the cleaning sponge, and adjust the temperature of the soldering iron to 300 ℃ again. Repeat the above procedure, and finally adjust the temperature of the soldering iron to the required temperature. The purpose is to form a comprehensive protective film on the solder head to prevent it from being oxidized at high temperature, resulting in heat transfer failure.

3. Select the appropriate temperature, too high temperature will weaken the function of the iron head, accelerate its oxidation, and relatively shorten the service life. It is suggested that the first heating temperature should not be too high (260 ℃) ° Cover the soldering iron head with tin to remove the oxide. In the case of operation, try to use lower temperature, lower temperature can also be fully welded, and can be divided into protection for temperature sensitive components. General we advocate the use of temperature 350 ~ 380 degrees. 350 ~ 360 degrees for small solder joints below 1.5mm and 370 ~ 380 degrees for large solder joints above 2.5mm.

4. If it is not used, turn off the power supply, clean the soldering tip on the cleaning sponge, and then put on a new layer of tin. Before reuse, clean the soldering tip on the cleaning sponge, and then put on a new layer of tin. Do not add any compound on the tin surface.
