What are the reasons for the rapid oxidation of the soldering iron tip?
1. The quality of the soldering head.
2. The temperature is too high, heats up quickly, and it is easy to burn the tip of the soldering iron. In addition, the temperature setting has a lot to do with the soldering iron you use. For example, the ordinary soldering iron you use requires a temperature of 350 degrees, and it may need to be adjusted to 380 degrees during use. Because the power is not enough.
Three, maintenance issues. It needs to be tinned every time it is used up to prevent oxidation.
4. The soldering iron tip is deformed or perforated.
Approach:
1. Poor quality soldering iron has high temperature, while good quality soldering iron generates heat slowly and low temperature, it is not easy to burn the tip of the soldering iron. The use of the soldering iron tip is very important to choose.
2. High temperature will accelerate the oxidation of the soldering iron tip and reduce the life of the soldering iron tip. The higher the temperature, the shorter the service life of the soldering iron tip. For every increase of 20°C, the service life of the soldering iron tip will be reduced by half.
3. Put the tip of the soldering iron into rosin and apply solder, roll it inside, and the oxide will fall off after a while. After normal use, cover the tip with tin until it can no longer stick. When you want to use it next time, wet it Rub it on the sponge and it will be very shiny.
4. Replace the soldering iron tip.
Precautions:
Do not use a file to remove oxides on the welding tip. If the tip of the electric soldering iron is burned to death (a dark layer that does not melt the tin, or it is just a tin ball when it melts), then use a blade to scrape the tip so that it exposes the copper part. The scraping speed should be fast, and do not use too much Vigorously, use solder wire to melt on it immediately after scraping, but if this is the case for a long time, the life of the soldering iron tip will be shortened
When the soldering station is not in use, do not keep the tip of the soldering iron at high temperature for a long time. This will convert the flux on the tip of the soldering iron into oxides, that is, oxidation of the tip of the soldering iron will cause the thermal conductivity of the tip to greatly decrease. When the soldering station is not in use, the power should be turned off (for non-temperature-controlled and non-automatic dormancy soldering stations).
