Enclosures, Manufacturing and Compliance

10 Lektionen in dieser Stufe

1. Choosing Enclosures and Understanding IP Ratings
   Select housing material and ingress protection for the intended environment. · Lab: Shortlist three enclosures for your product against its requirements.
2. Fitting a PCB into an Enclosure: Mounting, Cut-Outs and Indicators
   Coordinate board outline, mounting points and openings with the housing. · Lab: Export the board's 3D model or drawing, mark and machine one enclosure and mount the board.
3. Connectors, Cable Glands and Strain Relief
   Choose connectors for current, mating cycles and environment and secure cables mechanically. · Lab: Fit glands and connectors to the enclosure and perform a pull test.
4. Thermal Design and Condensation Control
   Estimate temperature rise in a sealed box and prevent moisture damage. · Lab: Log internal temperature and humidity of the closed enclosure over a day at full load.
5. Design for Manufacturing and Assembly
   Reduce assembly effort and error sources through part choice, orientation and panel features. · Lab: Review revision A against a manufacturing checklist and list changes for the next revision.
6. Bill of Materials, Second Sources and Component Lifecycle
   Produce a complete parts list with alternates and identify supply risks. · Lab: Create the bill of materials with cost per unit at 10 and 100 pieces and one alternate for each critical part.
7. Production Test Jigs and Factory Firmware
   Design a fixture and test firmware that verify every unit quickly. · Lab: Build a pogo-pin jig that powers the board, runs self-tests and reports pass or fail in under a minute.
8. Serial Numbers, Provisioning and Calibration Records
   Give each unit an identity, credentials and stored calibration with traceable records. · Lab: Provision three units with serial number, keys and calibration and keep a production log.
9. CE, UKCA and FCC Fundamentals: Which Rules Apply
   Identify the directives and standards relevant to a low-voltage radio product and the role of pre-certified modules. · Lab: Draft a compliance plan listing applicable requirements and the evidence you will need.
10. Technical File, Labels, Manuals and Declaration of Conformity
    Assemble the documentation a manufacturer must keep and supply. · Lab: Draft the label, a two-page user manual with safety notes and a declaration template for your product.
