The reason why the automatic soldering machine uses less paste 1, clean after welding: to weld the component lead, if there is oil or rust is not easy to eat tin. The soldering machine is equipped with a large transparent window, which can observe the entire welding process, which plays a very important role in product development and process curve optimization. Temperature control using high precision intuitive intelligent controller, programmable perfect curve control, accurate temperature control, simple parameter setting, easy to operate. Can complete CHIP, SOP, PLCC, QFP, BGA and other packaging form of single-sided, double-sided PCB board welding. Screw machine is a small machine that automatically locks screws, and the stability of quality performance is the key. With a welder plus a screen printing table, two workers can produce nearly 100 large size PCBS and thousands of small size PCBS in one day. The soldering machine changes the way that the welding machine can only rely on natural cooling or pull out the PCB board to cool the outside of the welding machine, making the reflow process curve more perfect, avoiding surface mount device damage and welding displacement problems. Even if the tin is attached very tightly, it will cause false welding. So be sure to scrape off any unnecessary items before applying the flux. Then dip the pin into the rosin and rub the pin back and forth with the tip of a tin-containing electric iron until the pin can be coated with a thin layer of solder. The weldability of most electronic components is very good, so manual welding does not need to be drip-tin treatment, which is not suitable for storage components, resulting in the need for drip-tin treatment if the element pin is oxidized or stained.
2, as far as possible to keep the welding stable without shaking: the welding material should be firmly clamped, especially in the welding stage, if the solidification stage is prone to false welding, the solder joint is like tofu residue, in order to make the wrist stable, you can use the support of the pillow, or sit or stand.
3, the amount of tin: solder enough of the impregnation has enough size of the welding coil is bright enough to allow the solder spot smooth, if not the tin can be added, but must wait for the front of the solder to melt together, then remove the tip, someone welding, like a nest of solder accumulation base. The result is also a lot of solder, but the solder is not strong.
4, master the temperature control skills: if the temperature is not enough, the flow of the wire is poor, easy to coagulate, the temperature is too high, resulting in drop welding, the solder joint can not be suspended.
For proper temperature control, use a soldering iron of the appropriate power according to the size of the object.
