What is Soldering Equipmentï¼
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.
Application method of dianluo iron:
1. Select appropriate soldering tin, and select low melting spot welding tin wire for welding electronic components.
2. Flux: dissolve 25% rosin in 75% alcohol (weight ratio) as flux.
3. Tin the electric soldering iron before use. The specific method is: heat the electric soldering iron, apply flux when the soldering tin can be melted, and then apply the soldering tin evenly on the soldering iron head to make the soldering iron head eat a layer of tin evenly.
4. Welding method: polish the pad and the pins of components with fine sandpaper and apply flux. Dip an appropriate amount of solder with the soldering iron head and contact the solder joint. After all the solder on the solder joint melts and immerses the component lead head, the electric soldering iron head gently lifts up along the pin of the component and leaves the solder joint.
5. The welding time should not be too long, otherwise it is easy to burn the components. If necessary, clamp the pins with tweezers to help dissipate heat.
6. The solder joint shall be in the shape of sinusoidal wave crest, the surface shall be bright and smooth, with Wuxi thorn and moderate amount of tin.
7. After welding, clean the residual flux on the circuit board with alcohol to prevent the carbonized flux from affecting the normal operation of the circuit.
8. The integrated circuit shall be finally welded, and the electric soldering iron shall be reliably grounded, or welded with waste heat after power failure. Or use the special socket for integrated circuit, and then plug in the integrated circuit after welding the socket.
9. The electric soldering iron shall be placed on the soldering iron frame.
