Definition

IPC-6012 establishes qualification and performance requirements for rigid printed board fabrication. It covers single-sided, double-sided, and multilayer boards with or without plated-through holes, blind/buried vias, and metal core constructions. The specification defines structural integrity, conductor requirements, hole quality, electrical properties, surface finishes, and testing frequency. When specifying PCBs, reference 'IPC-6012 Class 2' or 'Class 3' to invoke the appropriate acceptance criteria. Class 2 suits most commercial products; Class 3 is for medical, aerospace, and military where reliability is critical. Current version is IPC-6012F (2023).
