Assembly Documentation
Systematic collections of design, manufacturing, and test records verify that an electronic assembly complies with applicable regulatory and performance standards. Compilation of the technical dossier occurs during the development and qualification phases to demonstrate conformity before a product is placed on the market. This structural record includes circuit schematics, bill of materials, test reports, and compliance certificates.
The resulting documentation represents the primary evidence of product safety during audits by regulatory authorities.
Record Content
Complete schematics, fabrication drawings, and assembly instructions provide the exact description of how the circuit board is constructed. These files are accompanied by detailed descriptions of the components, including datasheets for wireless modules or safety-critical parts. The file must also contain the results of electromagnetic compatibility and safety testing, documenting that the board meets the limits of relevant standards.
Any changes made to the design or manufacturing process must be logged within the revision history to maintain traceability. This traceability helps ensure that any replacement part used during production does not compromise compliance.
Document Retention
Manufacturers are legally required to keep these compliance files accessible for a specified period, typically ten years after the last unit is placed on the market. In the event of a product failure or audit, quick access to this folder prevents regulatory fines and halts potential recall actions. This storage requirement is a standard part of quality management systems.
