AC 200-240V Solder Dross Recovery Machine Tig Automatic Soldering Machine

Describe

Soldering machine is a mechanical equipment, equipped with large size transparent window, can observe the whole welding process, product development, process curve optimization has a very important role. Temperature control adopts high precision intuitive intelligent controller, programmable perfect curve control, accurate temperature control, simple parameter setting, easy operation. Can complete CHIP, SOP, PLCC, QFP, BGA and other packaging forms of single, double sided PCB board welding. The work efficiency is very high, a welding machine with a screen printing table and two workers can complete nearly 100 PCB boards of the largest size and thousands of small size in a day. Soldering machine has changed the way that welding machine can only rely on natural cooling or pull out PCB board for cooling outside the welding machine, making reflow welding process curve more perfect, avoiding the damage of surface mount device and welding shift problem.

Method of use

1. choose the appropriate solder, should be used for welding electronic components with low melting point solder wire.

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

3. soldering machine before the use of tin, the specific method is: the electric iron is heated, to just be able to melt solder, coated with flux, and then coated with solder evenly on the iron head, so that the iron head evenly eat a layer of tin.

4. soldering machine welding method, the pads and components of the pin with fine sandpaper polished clean, coated with flux. Dip an appropriate amount of solder into the iron tip and touch the solder joint. After all the solder on the solder joint has melted and soaked the lead head of the component, the electric iron tip is gently lifted away from the solder joint along the pin of the component.

5. The welding time of soldering machine should not be too long, otherwise it is easy to damage the components. If necessary, tweezers can be used to clamp the pin to help heat dissipation.

6. soldering machine solder joints should be sinusoidal wave peak shape, the surface should be bright and smooth, wuxi thorn, tin content is moderate.

7. soldering machine after welding, to use alcohol to clean the residual flux on the circuit board, in order to prevent the charring flux affect the normal operation of the circuit.

8. the integrated circuit should be welded at last, the electric iron should be reliably grounded, or use waste heat welding after power failure. Or use a special socket for integrated circuits, and plug the integrated circuit in after welding the socket.

9. soldering machine should be placed on the iron rack.

Mechanical maintenance
Capacitor lead soldering machine
There are many kinds and specifications of soldering machine, and the size of the welding parts are different, so the reasonable selection of power and type of soldering machine, to improve the welding quality and efficiency has a direct relationship. Soldering machine soldering integrated circuits, transistors and heat vulnerable components, should choose 20W internal heat or 25W external heat soldering machine. When welding wires and coaxial cables, 45W~75W external heat soldering iron or 50W internal heat soldering machine should be used first. When welding larger components, such as the lead pin of the output transformer, the lead pin of the large electrolytic capacitor, the metal chassis grounding pad, etc., the soldering machine of more than 100W should be selected. Soldering machine iron must be enough temperature before starting to produce, this is also the occurrence of virtual welding more matters.

The lead wire of the soldering machine should not be too thin or too long. The voltage drop during welding should not be greater than 5% of the initial voltage, and the initial voltage should not deviate from the power supply voltage by ±10%. Gloves, apron and protective glasses should be worn when the welding machine is operated to avoid burns caused by sparks. The sliding part should be kept well lubricated and metal spatter should be removed after use. The screws of each part should be tightened once 24 hours after the new welder starts to use, especially the connecting screws between the copper soft connection and the electrode must be tightened, and the oxides between the electrode rod and the electrode arm should be removed frequently after use to ensure good contact. If the ac contactor is found to be false when the soldering machine is used, the power grid voltage is too low. Users should first solve the power supply problem, and the power supply can be used after normal. It should be pointed out that the newly purchased welding machine can be replaced with a new welding machine or a new main part if there is a quality problem of the main part within half a month. Soldering machine main part of the one-year warranty, long-term maintenance services. Under normal circumstances, after the user informs the factory, the service will be in place within three to seven days depending on the distance traveled. Welding machine damage caused by user's reason is not covered by warranty. Wearing parts, consumption parts are not within the scope of warranty.

Soldering machine solder joints can not be too saturated, too large solder joints and solder joints next to each other. Solder joints can not be too tin, which leads to virtual welding is often happened. The correct soldering machine solder joint is in the middle of three or four points, solder and component foot is small semicircle, unsaturated tin, so it seems that solder joint contact with components is the best, the circuit board is also the most neat. It is better to use adjustable soldering iron for soldering machine; Usually do not use the iron, to keep a certain amount of tin on the iron mouth, not the iron mouth in sponge after cleaning stored in the iron rack; Sponges should be kept moist throughout the day. Clean the tip of the soldering iron before using it.

Soldering machine in use process need to soldering iron mouth to sponge on clean, just put the soldering iron mouth of tin tin inside cardboard boxes loaded into set, so that keep the temperature of soldering iron mouth not fell sharply, if IC is tin extraction difficulty, add some tin up (for tin wire containing flux), you can easily extract more tin down; It is normal for the temperature of the soldering iron to be between 340 and 380 degrees. If some sensitive elements can only accept the welding temperature of 240 to 280 degrees. Soldering iron mouth hair, not with a blade such as metal device processing, but to use tin wire to solve; Every day after use, first clean, then add enough tin, and immediately cut off the power.
