Can a Rigid Printed Circuit Board Include Surface Mount Technology and Thru-Hole Technology?

In previous blog posts, we’ve explained the difference between surface mount technology (SMT) and thru-hole technology. The vast majority of rigid printed circuit boards (PCBs) use surface mount technology, because SMT components are smaller than thru-hole components and can be mounted on both sides of the board. This allows PCB manufacturers to place more SMT components on the board, which results in smaller PCBs that offer better performance than a thru-hole counterpart.

As we’ve previously written, there are some instances when it is a better idea to use a thru-hole PCB rather than an SMT, but are there any occasions to use both technologies on the same board?

The answer may surprise you. Yes. Certain components can only be attached to PCBs using the thru-hole method of drilling holes through the substrate of the board. If your board requires these components, then a manufacturer can create a hybrid board, one that utilizes thru-hole for those components and uses SMT for the rest. This will allow for the best use of space on the board.

Not sure whether your project requires SMT PCBs, thru-hole PCBs, or a hybrid? Give us a call, and we’d be glad to help.
