PCB Etching Reality — Why Copper Thickness Defines Minimum Track and Spacing

Etching defines what your PCB layout can and cannot achieve. Understanding the relationship between copper thickness, trace width, and spacing is not optional — it directly affects what your board costs and who can make it. How Etching Works — Downward and Sideways # The etchant does not only remove copper downward. It simultaneously attacks laterally — inward beneath the etch resist at the edges of every copper structure. This lateral attack is called undercut. The etch medium itself can be alkaline or acidic depending on the process — both attack copper selectively through the use of photo and metal resists as protective layers.

A precise quotation for a printed circuit board is not created simply by uploading layout data. It emerges from the interplay of complete manufacturing data, unambiguous technical specifications and a structured request for quotation. This is exactly where AI can make an important contribution — not as a replacement for the CAM engineer, but as an intelligent assistant at data intake. It can check data packages, evaluate documents, surface contradictions and prepare a clean foundation for an RFQ.
