Their substantial weight and texture immediately evoked memories from the early days of my career. I once assumed that through-hole technology was low-tech; only now do I realize that those dense arrays of holes conceal a wealth of intricate details. From structural mounting holes being misused as electrical vias\u2014leading to thermal dissipation issues\u2014to soldering failures caused by mismatched hole diameters, these experiences taught me that simple drilling operations require a delicate balance between electrical performance and practical manufacturing feasibility. Whether for manual soldering applications..."}
