Soldering station
is a necessary tool for electronic manufacturing and electrical maintenance. It is mainly used for welding components and wires. According to the mechanical structure, it can be divided into internal heating electric iron and external heating electric iron. According to the function, it can be divided into non tin absorbing electric iron and tin absorbing electric iron. According to different purposes, it can be divided into high-power electric iron and low-power electric iron.
Introduction to electric soldering iron structure
Electric soldering irons are divided into external heating type and internal heating type
External heating electric soldering iron is composed of soldering iron head, soldering iron core, shell, wooden handle, power lead, plug, etc. Because the soldering iron head is installed in the soldering iron core, it is called external heating electric soldering iron. The soldering iron core is the key component of the electric soldering iron. It is formed by winding the electric heating wire on a hollow porcelain tube in parallel. The mica sheet in the middle is insulated, and two wires are led out to connect with 220V AC power supply. There are many specifications of external heating electric soldering iron, including 25W, 45W, 75W, 100W, etc. the higher the power, the higher the temperature of the soldering iron head.
The internal heating electric soldering iron is composed of a handle, a connecting rod, a spring clamp, a soldering iron core and a soldering iron head. Because the soldering iron core is installed in the soldering iron head, it has fast heating and high heat utilization rate. Therefore, it is called internal heating electric soldering iron. The common specifications of internal heating electric soldering iron are 20W and 50W. Because of its high thermal efficiency, 20W internal heating electric soldering iron is equivalent to about 40W external heating electric soldering iron. The rear end of the internal heated electric soldering iron is hollow, which is used to be sleeved on the connecting rod and fixed with a spring clamp. When the soldering iron head needs to be replaced, the spring clamp must be pulled out first, and the front end of the soldering iron head must be clamped with pliers and pulled out slowly. Remember not to use too much force to avoid damaging the connecting rod.
What is Soldering Used for?
Soldering is used for a variety of applications, from repairing electronics to making jewelry to soldering pipes in plumbing. Depending on what you’re soldering, different types of solders, materials, and techniques might be used.
When soldering jewelry, for example, solderers would avoid lead solder (which can be hazardous to health) and opt for solder high in silver. The solder usually comes in thin sheets instead of soldering wires.
Those soldering for plumbing are forbidden from using lead solder because of the potential for lead poisoning. Instead, their solder of choice is lead-free and usually comes in bars (instead of solder paste or solder wire). The solder flux used for plumbing is also unique, being too corrosive (or even conductive) for most electronic soldering applications.
Soldering electronics is another popular application. Many use soldering to repair electronics or create their own circuit boards by soldering SMDs to PCBs. This type of soldering is often called through-hole soldering because the electronic components are placed through a hole in the PCB and are soldered to the board from the underside.
Solder as an artform in itself is another compelling use for soldering. Solders can even provide a framework for stained glass windows or even melt to form pictures and sculptures. You can even create model LED sculptures, such as our LED Canton Tower Model Soldering Project Kit.
