SMT and DIP are all parts of the PCB board. The main difference is that the SMT doesn't need to drill holes in the PCB, and the DIP needs to insert the PIN foot of the part into the hole that has been drilled.
SMT (Surface, Mounted, Technology)
SMT technology mainly uses SMT to mount some small parts to PCB board, and its production process is PCB plate positioning, printing solder paste, paste mount, reflow oven and inspection. With the development of science and technology, SMT can also mount some large size parts, such as the main board can be fitted with some larger size of the body parts.
SMT integration is sensitive to location and part size, and the quality of solder paste and printing quality also play a key role.
DIP, that is, the plug-in, that is, insert parts on the PCB version, due to the larger size of the parts, and do not apply to the mount, or manufacturers can not use SMT technology production process, the use of plug-ins in the form of integrated parts. At present the industry with artificial plug-ins and two ways of realizing robot plug-in, its main production process is as follows: (to prevent sticking gum tin plating should not place), plug-in, inspection, wave soldering, brush Version (left in the furnace in the process of removing stains) and made the inspection.
