Have you ever looked at a circuit board and wondered why it has so many tiny holes? They may look insignificant, but many of them are actually essential to how modern electronics work. In this video, we explore the fascinating engineering behind PCB holes, vias, plated-through holes, blind vias, and buried vias. We’ll look at how these tiny copper-lined pathways connect different layers of a circuit board, allowing electrical signals and power to move through an incredibly compact space. What looks like a simple hole is actually part of a carefully engineered three-dimensional electrical network. ⏱️ Timestamps 00:03 – Why Do Circuit Boards Have So Many Tiny Holes? 00:54 – A Brief History of Circuit Boards 01:57 – They're Not Just Holes 03:01 – How Can a Tiny Hole Carry Electricity? 03:54 – Why Are There So Many? 04:54 – Through, Blind & Buried Vias 05:35 – How Are These Tiny Holes Made? 06:34 – The Engineering Trade-Offs 07:27 – Why These Tiny Holes Matter #CircuitBoard #PCB #Elect
