ApplICation of SMT chip in LED
Surface Mount Technology (Surface Mounted Technology) (abbreviation of surface mounted Technology) is the most popular technology and process in the electronic assembly industry Surface mount patch is an abbreviation for a series of technological processes based on PCB processing PCB (PrintedCircuitboard) means printed circuit board.  Surface mount patch is an abbreviation for a series of technological processes based on PCB processing PCB (PrintedCircuitBoard) means printed circuit board.  Surface mount technology (Surface Mounted Technology) (abbreviation of Surface Mounted Technology) is the most popular technology and process in the electronic assembly industry Electronic circuit surface mount technology (SurfaceMountTechnology) is called surface mount or surface mount technology It is a kind of surface assembly components without leads or short leads (SMC/SMD abbreviation, chip components in Chinese) mounted on the surface of a printed circuit board (PrintedCircuit board, PCB) or the surface of other substrates
Under normal circumstances, the electronic products we use are designed by PCB plus various electronIC components such as capacitors and resistors according to the designed circuit diagram. In addition, all kinds of electrical appliances need various SMT wafer processing technologies to process.

components of surface mount basic process: Solder paste printing -->Part placement -->Reflow soldering -->AOI optical inspection -->Maintenance -->Sub board
Some people may ask why connecting electronic components is so complicated? This is actually closely related to the development of our electronic industry Nowadays, electronic products are pursuing miniaturization, and the perforated plug-in components used in the past can no longer be reduced Electronic products have more complete functions The integrated circuits (ICs) used have no prefabricated components, especially large-scale and highly integrated integrated circuits, must use surface mount components For large-scale production and production automation, factories must produce high-quality products with low cost and high output to meet customer needs and enhance MARKet competitiveness The development of integrated circuits (IC) and diversified application of semiconductor materials The electronic technology revolution is imperative and follows the international trend It can be imagined that in the case of Intel, the production process of amd and other international CPU and image processing equipment manufacturers has been improved to more than 20 nanometers. The development of surface mount technology, such as surface mount technology and process, can not be ignored Advantages of SMT chip processing: high assembly density, SMAll size and light weight of electronic products The volume and weight of the chip module is only about 1/10 of that of the traditional chip module Generally, after surface mounting has been adopted, the volume of electronic products has been reduced by 40% - 60%, and the weight has been reduced by 60% - 80% High reliability and strong anti vibration capability defect rate is low Good high frequency characteristics Reduce electromagnetic and radio frequency interference It is easy to realize automation and improve production efficiency Reduce cost by 30% - 50% Keep data, energy, equipment, labor, time, etc
