SMT and DIP are both ways to integrate parts on the PCB. The main difference is that SMT does not need to drill holes on the PCB. In DIP, the PIN pins of the parts need to be inserted into the holes that have been drilled.
SMT(Surface Mounted Technology)
Surface mount technology mainly uses mounters to mount some tiny parts on the PCB. The production process is: PCB board positioning, solder paste printing, mounter mounting, reflow oven and final inspection. With the development of technology,
SMT can also mount some large-size parts, for example, some larger-size mechanical parts can be mounted on the motherboard.
Dip stands for "plug-in", that is, inserting parts on the PCB board. Because the parts are large in size and not suitable for placement or the manufacturer's production process cannot use SMT technology, the parts are integrated in the form of plug-ins.
At present, there are two implementation methods of manual plug-in and robot plug-in in the industry. The main production process is: sticking adhesive (to prevent tin plating to the place where it should not be), plug-in, inspection, wave soldering, and brushing (removing in the furnace Stains left in the process) and made inspection.
