smt patch processing is a series of process processes based on PCB. SMT is a surface assembly technology (surface mount technology), is currently a popular technology and process in the electronic assembly industry. smt chip processing refers to the short term of a series of process processes based on PCB, PCB is a printed circuit board.
Surface assembly technology (SMT), also known as surface mount technology, is a new generation of electronic assembly technology. It compresses traditional electronic components into only a few tens of the volume of the device, from the surface to achieve the assembly of electronic products of high density, high scalability, miniaturization, low cost and production automation.
In a narrow sense, SMT is an electronic mounting technology that attaches and welds Surface Mount Component (SMC) and Surface Mount Device (SMD) to the specified position on the surface of the printed circuit board (PCB) as the assembly substrate. The PCB used does not need to drill and insert holes, and is refined from the process point of view, that is, first apply solder paste on the PCB pad, and then accurately place the surface assembly components on the pad coated with solder paste, and realize the interconnection between the components and the printed circuit after heating the PCB until the solder paste melts.
Under normal circumstances, the electronic products we use are all designed by pcb plus a variety of capacitors, resistors and other electronic components according to the design of the circuit diagram, so all kinds of electrical appliances need a variety of different smt patch processing technology to process.
