Types of Vias on PCBs

When it comes to PCB design, it’s essential to differentiate between thermal vias and normal vias. Thermal vias are designed to be plated over with copper and filled with epoxy for better heat dissipation. On the other hand, normal vias are not plated over or filled with epoxy.

If you’re wondering how to communicate this distinction to the PCB assembler, it’s crucial to provide clear instructions as this information may not be included in the gerber files.
