Mixed Assembly
What Is Mixed Assembly

Mixed assembly requires the application of SMT components and THT components on the same board, and this type of PCB component does not use any solder paste, this technology is called mixed assembly.

Comparision Of Through-Hole Assembly And Surface Mounting Technology

(1) First, SMT components are soldered on the board by a reflow soldering machine, while THT assembly requires pre-drilling holes on the board and the use of leads to connect components and circuits.

(2) Second, reflow or wave soldering can be used for SMD components, but only wave soldering for TNT components. Therefore, the steps of mixed assembly will be more complicated. For mixed assembly, usually, the SMT process is performed first, and then the THT assembly is performed.

(3) Third, SMT is generally suitable for mass production and high-density small PCBs, and THT is generally suitable for prototype manufacturing and products that are prepared to withstand mechanical stress.
