Plan stacked PCB mounting in plastic electronic enclosures using spacing, fasteners, connectors, heat, cable paths, service access, and verification. Treat certification and compliance as project-specific evidence; confirm the applicable standard, listing scope, responsible party, and qualified review before release.
Define the product and evidence boundary
Record the enclosure, components, environment, mounting, wiring, access, maintenance, and the exact evidence required from the supplier, integrator, installer, or testing body.
Inputs to document
| Input | Why it matters |
|---|---|
| Physical and electrical layout | Device dimensions, PCB spacing, connectors, battery or power, cable entry, clearances, mounting, and service access. |
| Environment and materials | Heat, moisture, dust, UV, impact, chemical exposure, sealing, material, and cleaning or handling conditions. |
| Evidence and labeling | Part identity, drawings, material data, test reports, markings, supplier declarations, and limitations of any listing or classification. |
| Verification and handover | Inspection points, assembly checks, test records, manuals, replacement instructions, and unresolved assumptions. |
Do not transfer another supplier’s certification, flame, IP, safety, or performance claim to the complete project without matching evidence.
