Maintenance and use of soldering iron tip when soldering with lead-free soldering station
1. Preparations before using the soldering station
It is necessary to check whether the cleaning sponge is soaked in water first. Wet the cleaning sponge with water first, and then squeeze out the excess water. Only in this way can the lead-free soldering iron tip get a good cleaning effect. If you use a non-wet cleaning sponge, it will damage the tip and cause no tinning.
2. Protection during welding work
Before welding on the soldering station, use a cleaning sponge to clean the impurities on the welding tip, which can ensure the quality of the solder joints without false welding or false welding, and can slow down the oxidation speed of the welding tip. Therefore, ensuring the cleanliness of the welding tip can prolong the service life of the welding tip.
3. Protection after the welding work of the welding station
First adjust the temperature to 300°C, then clean the solder tip, and then add a new layer of solder for protection, so as to protect the solder tip from the air, and the solder tip will not oxidize with the oxygen in the air.
4. Protection when the soldering station is not in use
When the soldering station is not in use, do not keep the solder tip at high temperature for a long time, as this will convert the flux on the soldering iron tip into oxides, resulting in a significant decrease in the heat conduction function of the soldering iron tip. When the soldering station is not in use, the power should be turned off (for non-temperature-controlled soldering stations without automatic sleep function).
How to choose lead-free soldering station is more formal
Lead-free soldering station has a relatively large influence on our welding tools, and it is the leader of our welding tools. We must first ensure two points when purchasing a lead-free soldering station, which can help the life of the soldering iron tip to a certain extent. , is also an important feature in welding:
1. For the selection of temperature, first of all, ensure that the welding temperature is about 350°C, and it should not deviate from too high or too low;
2. The lead-free soldering station is mainly for solder joints to ensure that the welding speed is 3-4 seconds per solder joint, which is more suitable;
The lead-free soldering station can only be counted as a lead-free soldering station if it can guarantee the above two points, and it is not advisable to increase the welding temperature by ensuring the welding speed, and it will also affect the life of the soldering iron tip. Certain impact, and this will affect the quality of solder joints and shorten the use of soldering iron tips have a lot of requirements.
As far as we know, lead-free soldering stations generally have several powers of 80W, 100W, 120W, 150W, and 200W. The so-called 80W lead-free soldering stations can satisfy most solder joints. Choose a lead-free soldering station with higher power , This can be regarded as a real soldering iron tip. If we want to choose or buy a soldering iron tip, we must at least meet the above two points.
