The characteristics of SMT process technology can be compared with the traditional through hole insertion technology (THT). From the perspective of assembly process technology, the fundamental difference between SMT and THT is "stick" and "plug". The difference between the two is also reflected in the substrate, components, component form, solder joint morphology and assembly process methods.
THT uses leaded components to design circuit connections and mounting holes on the printed board. Insert the component leads into the pre-drilled vias on the PCB. After temporary fixing, the other side of the substrate is soldered by soldering techniques such as wave soldering to form a reliable solder joint. Establish long-term mechanical and electrical connections, with component bodies and solder joints distributed on both sides of the substrate.
With this method, since the components have leads, when the circuit is dense to a certain extent, the problem of shrinking the volume cannot be solved. At the same time, the failure caused by the proximity of the leads and the interference caused by the lead length are difficult to eliminate.
