Any non-standard assembly step, such as manual solder, conformal coating, potting, torqued fasteners, or serialization, requires a written work instruction specifying materials, parameters, and locations.
- Any non-standard assembly step requires a written work instruction (e.g., manual solder, cable routing, epoxy application)
- Conformal coating: specify coat type (acrylic, urethane, silicone), thickness, and masked areas
- Potting / encapsulation: specify material, cure schedule, and fill level
- Torque specs: provide for all mechanical fasteners
- Label/serialization: provide label artwork, serial number format, and placement spec
