What is smt patch for?

SMT patch is a circuit assembly technology in which surface assembly components (SMC/SMD) without leads or short leads are mounted on the surface of printed circuit board (PCB) or other substrates, and then soldered and assembled by reflow soldering.

Due to the progress of science and technology and the requirements of technology, the components on the circuit board are required to be smaller and smaller, and the efficiency is higher, so surface mount components (components without leads or short leads) are developed. These components occupy very little space, so the efficiency of SMT mounting with mounter is very high, and the problems are getting smaller and smaller. This is a manifestation of scientific and technological progress.

SMT patch refers to pcb (printed circuit board), which is a series of technological processes based on PCB. The Chinese name is printed circuit board, also known as printed circuit board and printed circuit board. SMT patch is an important electronic component, a supporter of electronic components and a provider of electrical connection of electronic components. Because it is made of electronic printing, it is called "printed" circuit board.

SMT technology has the advantages of high assembly density, small size and light weight of electronic products. The size and weight of the patch component are only about110 of the traditional plug-in component. Generally, after SMT is adopted, the size of electronic products is reduced by 40%~60% and the weight is reduced by 60%~80%. High reliability and strong earthquake resistance. The defect rate of solder joints is low. Good high frequency characteristics. Reduce electromagnetic and radio frequency interference. It is easy to realize automation and improve production efficiency. Reduce the cost by 30%~50%. Save materials, energy, equipment, manpower, time, etc.
