Definition

Compliance encompasses regulatory requirements (RoHS, REACH, UL) and industry standards (IPC, ISO) that PCBs and assemblies must meet. RoHS restricts hazardous substances; UL certifies flammability; IPC defines quality classes. Compliance affects material selection (lead-free, halogen-free), testing (flammability, electrical), and documentation (certificates of conformance, material declarations). Non-compliance can block market access or create liability. Design for compliance early - retrofitting lead-free or meeting unexpected requirements is expensive. Specify compliance requirements in fabrication drawings.
