Web8 Feb 2024 · What is PCB tenting vias? As mentioned above tenting vias in PCB is the process of coating the vias' annular ring. Tenting is preferred over the filling, in many cases, as we shall see. During tenting, a solder mask is … Tenting is best used on small vias with a finished hole diameter of less than about 12 mil. The specific diameter limit depends on the LPI solder mask solution, and your fabricator should be able to recommend a maximum via diameter to ensure reliable tenting. If the via diameter is too large, the solder resist could … See more Vias placed close to SMD components may provide a path for solder wicking onto the back side of the board.
