Yes,…through-hole and surface-mount technology (SMT) components can be placed on the identical PCB. This combination allows for a mix of technologies to be used based on the requirements of the design. Remember that you may need to consider factors like component compatibility, assembly processes, and layout considerations when combining these components.

It is common to combine through-hole and SMT components on a single board to take advantage of the benefits each type offers. Through-hole components have longer leads that can be soldered into plated through-holes on the board, providing mechanical stability and reliability. On the other hand, SMT components have smaller footprints. They can be soldered directly onto the surface of the PCB, allowing for higher component density, reducing the size of the board, and improving electrical performance.

When designing a PCB that incorporates both through-hole and SMT components, it is essential to ensure enough space and proper clearance for each component type and that the appropriate soldering processes are used for each component. With that in mind, go ahead and combine through-hole and SMT components.
