Reasons for using less slurry in automatic soldering machine
1. Clean after welding: lead in the welding element. If there is oil stain or rust, it is not easy to eat tin. The welding machine is equipped with a large transparent window to observe the whole welding process, which plays an important role in product development and process curve optimization. Temperature control adopts high-precision intuitive intelligent controller, programmable perfect curve control, accurate temperature control, simple parameter setting and convenient operation. It can complete the single-sided packaging forms such as CHIP, SOP, PLCC, QFP, BGA, and the welding of double-sided PCB boards. Screw machine is a small machine that automatically locks screws. The stability of quality performance is the key to Z. A welder and a screen printing station, two workers can produce nearly 100 Z large PCBs and thousands of small PCBs in one day. The welding machine has changed the way that the welding machine can only rely on natural cooling or pull out the PCB board to cool outside the welding machine, making the reflow process curve more perfect, and avoiding the damage of surface mounting device and welding displacement problems. Even if the tin is stuck tightly, it will cause false soldering. So before using the flux, you must scrape off those unnecessary things. Then immerse the pin in rosin, and rub the pin back and forth with the tin tip until the pin can be coated with thin solder. Most electronic components have good solderability, so manual welding does not need tin dripping treatment, which is not suitable for storing components, resulting in oxidation or dirt of component pins, that is, tin dripping treatment is required.
2. Try to keep the welding stable and not shaking: the welding material should be firmly clamped, especially in the welding stage. If false welding is easy to occur in the solidification stage, the welding spot is like bean curd residue. In order to stabilize the wrist, you can support it with a pillow, or sit or stand.
3. Tin content: enough solder impregnation, enough bright welding coil, enough to make the solder joint smooth. If tin cannot be added, you must wait for the previous solder to melt, and then delete the prompt that someone is welding, just like the base of the nest solder accumulation. The result is also a large number of welding materials, but the welding materials are not firm.
4. Master the temperature control skills: if the temperature is not enough, the welding wire fluidity is poor, it is easy to solidify, and the temperature is too high, resulting in dripping welding, and the solder joint cannot be suspended.
