Pcb cleaning skill:solder cleaning&desolering

After the PCBA soldering process, there will generally be some solder scars left by the solder on the circuit board, which will not endanger the application of the circuit board after cleaning.
With the development of science and technology and the improvement of professional and technical personnel, there are more and more ways to remove welding scars.

Hold the part on top of the pads using the tweezers and heat the pad using the soldering iron.
Apply heat on the joints in a circular motion. The iron will melt the paste. The flux will burn off.

For electronic printed circuit board (PCB) assembly, you will find isopropyl alcohol being used to clean flux residues from recently soldered circuit boards or in PCB repair and rework. Using pcb cleaner is the most way .

Surface mount technology is a part of the electronic assembly that deals with the mounting of electronic components to the surface of a PCB. Electronic components mounted this way are called surface-mounted devices (SMD). SMT was developed to minimize manufacturing costs while making efficient use of board space.Qihe SMT company develops and produces all kinds of SMT equipment suitable for world wide market, including pnp machine,reflow oven,stencil printer,pcb handling machines,and other products.

It has more than ten years of user experience, combined with the algorithm improvement of world-renowned colleges, and the most advanced flying camera and motion system. It is your best choice. The system is friendly for beginners and professionals.

With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.
