.@sfcircuits takes an in-depth look at Via Tenting, the practice of using a soldermask layer to cover the via holes on a Printed Circuit Board (PCB). Learn more: hubs.la/Q02mlPzj0 #circuitboard #engineering #tech #circuit


Tenting vias with a soldermask layer, or leaving them untented, has its own set of advantages & disadvantages that designers should consider for each project.  Check out our new article on Via Tenting Principles in PCB design here: ow.ly/Hsqu50QCCMb  #PCBdesign
