How does SMT assembly work? | |
SMT Assembly is a technology in PCB manufacturing that uses reflux welding technology or immersion welding process to install electronic no pin or short lead surface mount PCB assembly elements on the printed circuit board. Great PCB is a professional PCB & PCBA factory, with many years of industry experience, with advanced SMT PCB assembly equipment and technology, can meet the various needs of customers, to provide customers with a full range of SMT assembly services. The SMT assembly process Tin paste printing Print the tin paste on the welding pad of the PCB to prepare for the welding of the circuit board components. The tin paste printing press is located at the front end of the SMT production line. Part loading Its function is to accurately install the surface assembly components to a fixed position of the PCB. The equipment used is the patch machine, which is located behind the printing machine in the SMT production line. It is generally used with high-speed machines and general machines according to the production requirements. reflow soldering Melt the welding paste to make the surface assembly components firmly welded together with the PCB plate. The equipment used is the reflux welding furnace, which is located behind the patch machine in the SMT production line. The temperature requirements are quite strict, so real-time temperature measurement is required, and the measured temperature is reflected in the form of a profile. The AOI optical detection Its function is to test the welding quality of the welded PCB plate. The equipment used is an automatic optical detector (AOI), which can be configured in the appropriate place of the production line according to the detection needs. Some are before reflux welding, and some are after reflux welding. Servicing Its function is to repair the PCB board to detect failure. The tools used are soldering iron, repairing workstations, etc. Configure it after the AOI optical detection. Split board PCBA is divided into separate individuals, generally using V-cut and machine cutting. Great PCB SMT The advantages of patch processing service are mainly reflected in the following aspects: High efficiency: Great PCB has a number of automated production lines, Using advanced equipment and technology, can realize automatic patching, automatic welding, automatic testing, and other processes, can achieve 24-hour uninterrupted production, and can meet customer needs. Low cost: Great PCB has a complete supply chain system, can provide customers with high-quality components and raw materials, and reduces production costs. Provide customers with preferential prices and quality service. High reliability: Great PCB has a strict quality control system, uses advanced testing equipment and technology, and a full range of products to ensure that the quality of products meets the requirements of customers. | |
