The use specification of the thermostatic soldering iron, how to adjust the temperature of the elect

Hehe! Specification is very troublesome! In fact, the main point is that the soldering iron tip is tinned, and you can cut off the power supply when you don't use it! You can design a soldering iron mount! When not in use, it can automatically cut off the power and maintain the temperature!

There is a knob with a +- symbol on it, and pressing the + end to rotate should be warming, and to-rotate is cooling.

It is an essential tool for electronic production and electrical maintenance, the main use is soldering components and wires, according to the mechanical structure can be divided into internal heating electric soldering iron and external heating electric soldering iron, according to the function can be divided into non-soldering iron and tin-absorbing electric soldering iron, according to different uses are divided into high-power electric soldering iron and low-power electric soldering iron.

The externally heated electric soldering iron is composed of a soldering iron tip, a soldering iron core, a shell, a wooden handle, a power lead, a plug and other parts. Because the soldering iron tip is installed inside the soldering iron core, it is called an externally heated electric soldering iron. The soldering iron core is the key component of the electric soldering iron, which is composed of the heating wire wound parallel to a hollow porcelain tube, the mica sheet in the middle is insulated, and two wires are connected to the 220V AC power supply.

1. To select appropriate solder, low melting point solder wire for soldering electronic components should be selected.

2. Flux, dissolved in 25% rosin in 75% alcohol (weight ratio) as flux.

4. Soldering method, polish the pad and the pins of the component with fine sandpaper and apply flux. After all the solder on the solder joint is melted and submerged in the component lead, the soldering iron tip is gently lifted up along the pins of the component to leave the solder joint.

5. The welding time should not be too long, otherwise it is easy to burn the components, and if necessary, you can use tweezers to clamp the pins to help dissipate heat.

6. The solder joint should be in the shape of a sine crest, the surface should be bright and smooth, with tin-free thorns and a moderate amount of tin.

7. After the soldering is completed, the residual flux on the circuit board should be cleaned with alcohol to prevent the carbonized flux from affecting the normal operation of the circuit.

8. The integrated circuit should be soldered last, and the electric soldering iron should be reliably grounded, or the waste heat should be used for soldering after the power is off. Or use a special socket for integrated circuits, and then plug in the integrated circuit after soldering the socket.

The soldering iron temperature control device, also known as the soldering station, can realize different temperature adjustment of the soldering iron and adapt to soldering different components.

First plug in the soldering iron, plug in the power, turn on the switch, the soldering iron starts to heat, the other button is a different temperature range, choose the right temperature.

The welding element is small, the melting point of the welding wire is low, and the low-grade temperature is selected, and the high-grade temperature is selected vice versa.

The easiest way to do this is to find a multi-position ceiling fan switch and connect the heating wire of the soldering iron. to meet the requirements. Another way is to use power devices to do it yourself; Then there is the purchase of a ready-made thermostatic soldering iron.

The use of an electric soldering iron requires a simple temperature adjustment, which is easy to use and can also extend the life of the electric soldering iron. For example, a 220V30W electric soldering iron, the simplest way is to connect the components of [diode or 40W ordinary bulb and single-pole switch in parallel] in the electric soldering iron circuit, close the switch when you need to weld, so that the electric soldering iron can enter 220V voltage, and when you do not need to weld, disconnect the switch, so that the electric soldering iron is in the 110V DC or about 150V AC voltage range, which belongs to the part state at this time.

Tempering of the soldering iron.

The soldering core of the electric soldering iron is under 220V alternating current, and the heating heat is constant, that is, the constant temperature.

In order to achieve temperature regulation, you can only start with the input voltage, and you can use a voltage regulator to adjust the input voltage of the electric soldering iron and change the temperature of the electric soldering iron.

If you feel that the temperature is too high when using 220V, reduce it to 200V or 180V to make the temperature of the soldering iron suitable for the desired temperature.

There should be one that is the temperature control key.

The thermostatic electric soldering iron is through the attraction and separation of soft magnetic materials and magnets to achieve automatic temperature control. The constant temperature electric soldering iron is generally 45W, intermittently energized and power-off, the actual power consumption is 25W, and the transformer is used for 24V power supply, AC and DC dual-use. Thermostatic electric soldering iron has the advantages of energy saving, high efficiency, low consumption and long life, and is an ideal soldering tool for electronic product production and electronic repair industry.

When soldering integrated circuits, transistors and their components that are vulnerable to heat, consider using a 20W internal heating or 25W external heating electric soldering iron. When soldering thicker wires or coaxial cables, consider using a 50W internal heating or 45 75W external heating electric soldering iron. When welding larger components, such as metal chassis grounding solder tabs, an electric soldering iron of more than 100W should be used.

The shape of the soldering iron tip should be adapted to the surface requirements of the welded parts and the assembly density of the product.

Must be connected, 936 constant temperature electric soldering iron, there are two characteristics: one is that the temperature can be adjusted, the other is that the heating core uses 24V power supply, the use of 24V transformer is to prevent the generation of static electricity and safety, the ground wire is a circuit that releases static electricity, and the ground wire is gone, which is equivalent to the electric soldering iron is missing a function, it is no different from the ordinary soldering iron, and the ordinary soldering iron is cheaper.

Precautions should be taken when using an electric soldering iron:

1. When using an electric soldering iron for soldering operation, there are a variety of gripping methods for the electric soldering iron, mainly including forward grip, reverse mention, pen grip, etc.

No matter what kind of grip method is used, you must pay attention to the direction of the power wire, which should be drawn from the back of the hand or the direction of the arm, and the wire should not be placed in the direction of the soldering iron tip to prevent burning the wire and causing danger.

2. During the use of the electric soldering iron, it should not be placed at will, but should be placed on a suitable soldering iron frame to avoid damage to the electric soldering iron tip due to collision; At the same time, you should also pay attention to handling with care.

Place the soldering iron can not be close to flammable and explosive objects, avoid scalding, scalding items, and cut off the power supply in time after the use of the electric soldering iron. Extend the life of the soldering iron. Prevents oxidation of the soldering iron tip.

3. When using the soldering iron for the first time, it is easy to make some mistakes, such as: whether the soldering iron is used immediately or not, always plug the soldering iron into the power supply first, so that the soldering iron is in working condition.

When you want to use an electric soldering iron, you find that the temperature of the soldering iron is too high or the oxidation of the soldering iron tip is serious, and it is difficult to use Some users think that as long as the electric soldering iron has heat, they can solder components regardless of the situation of the soldering iron tip.

In the case of thick oxide layer or dirt, long-term soldering will not only have poor soldering quality, but also cause the circuit board pads to fall off or components to be soldered.

4. When welding, the electric soldering iron is processed first, and then welded, which not only solders, but also saves soldering time.

5. After cutting off the power supply, it is best to use the residual heat to put a layer of tin on the soldering iron tip to protect the soldering iron tip.

6. The sponge is used to collect tin slag and tin beads, and it is suitable to pinch it just without water by hand.

7. Do "5S" before welding, and "5S" after welding.
