What factors should be considered when choosing a soldering iron
An electric soldering iron is a crucial equipment for manufacturing electronic products and maintaining electrical systems. Its primary use is to weld cables and components. It can be divided into internal heat type electric soldering irons and external heat type electric soldering irons based on mechanical structure. According to their different uses, tin-type soldering irons are divided into high-power and low-power soldering irons.
The efficiency of our soldering iron tip in electronic lead-free soldering can be greatly increased by selecting a suitable electric soldering iron, but typically, the choice should be based on the actual situation of the object to be welded, with a general focus on the heating form, power size, and soldering iron tip. shape, etc.
Depending on the electric soldering iron's heating method of choice
1. When choosing between an internal heating type and an external heating type, keep in mind that the internal heating type soldering iron will reach a higher temperature under the same wattage.
2. Use a voltage regulator to regulate the temperature of the electric soldering iron when low-temperature soldering is necessary. The voltage of the power source has a direct impact on the temperature of the electric soldering iron. In actual use, lowering the power supply voltage frequently results in a decrease in the temperature of the electric soldering iron.
3. Adjust the soldering iron tip's extension length to control the temperature.
4. The most common ways to maintain the temperature of an electric soldering iron are as follows: install a stabilized power supply to prevent changes in the power supply network; maintain a specific volume, length, and shape of the soldering iron head; use an electric soldering iron with a constant temperature; maintain a constant indoor temperature; avoid using an electric fan or natural wind; etc.
According to the selection of electric soldering iron power
1. It is recommended to use a 30-45W external heating type or a 20W internal heating type electric soldering iron for soldering small-wattage resistance-capacitance components, transistors, integrated circuits, pads of printed circuit boards, or plastic wires. For this purpose, a 20W internal heating type electric soldering iron is recommended.
2. It is recommended to use a 75–100W electric soldering iron when welding the soldering points of general structural products like wire loops, wire claws, heat sinks, grounding soldering pieces, etc.
3. A 100–200W electric soldering iron is recommended for large solder joints, such as welding metal rack tabs, solder tabs, etc.
