The first type is single-sided hybrid assembly, that is, the SMC/SMD and the through-hole component are distributed on different sides of the PCB, but the soldering surface is only one side. This type of assembly uses a single-sided PCB and wave soldering process, specifically in two ways.
(1) First paste method. The first type of assembly is called the first paste method, that is, the SMC/SMD is placed on the B side (welding surface) of the PCB, and then the THC is inserted on the A side.
(2) Post-paste method. The second assembly method is called post-paste method. It is to insert THC on the A side of the PCB and then mount the SMD on the B side.
The second type is double-sided hybrid assembly. SMC/SMD and THC can be mixed and distributed on the same side of the PCB. At the same time, SMC/SMD can also be distributed on both sides of the PCB. Double-sided hybrid assembly uses double-sided PCB, dual wave soldering or reflow soldering. In this type of assembly method, there is also the difference between paste first SMC/SMD and paste after SMC/SMD. Generally, it is reasonably selected according to the type of SMC/SMD and the size of the PCB,the first paste method is usually used. (Electronic Manufacturing Services)
