The tip is the most essential part of the tool. While the soldering iron holds and heats the tip and controls performance, the tip has the most important job of transferring heat efficiently and reliably to the solder joint.
In most cases, the factor that most influences the duration of a tip is the working temperature.
Before theROHS regulation (Restriction Of Hazardous Substances) came into effect on the 1st July 2006, solder wire that contained lead was permitted. After this date the use of lead was prohibited (as well as other substances) in all equipment and processes except the following: medical apparatus, monitoring and surveillance equipment, measuring instruments and equipment specifically designed for the military and space industry as well the car sector (car control systems, airbags, etc.), rail transport, etc.
The special characteristic of the most common lead alloys is that the fusion occurs at around 180°C. With the most common lead-free alloys this happen approximately at 220°C. So the difference of 40°C meant it was necessary to increase the temperature of the solder tool to achieve a solder joint in the same length of time (if soldering time is increased, then the components and the printed circuits may be damaged) and this reduced the life of the tips and increased oxidation.
With the implementation of lead-free soldering, besides the wet sponge there are alternative ways to cleaning the tip. Their use depends on how much residue needs to be removed, maintenance and the technology of the soldering method.
The following guidelines will help you choose the most convenient method for cleaning your tips. Read on!
If you are experienced in hand soldering, you will know that the tip is the most essential part of the tool. While the soldering iron holds and heats the tip and controls performance, the tip has the most important job of transferring heat efficiently and reliably to the solder joint. Inadequate or improper tip maintenance and use are principle causes of soldering problems.
Early soldering irons were very basic and were not very good for electronics soldering. There was no heat control and every time you placed the tip on a joint, the tip would cool down. Today’s stations have overcome these problems. But if you want to solder the right way, without getting frustrated the iron, and get professional results, read on.
Almost all stations have a menu with some parameters adjusted to maximize equipment performance and correctly manage the soldering process. Which parameters should be modified?
