PCB Electronics Enclosure Design & Mechanical CAD Development

This project focused on developing a compact electronics enclosure designed to accommodate a PCB assembly and its internal components while maintaining a practical, organized housing structure.

The design combines a protective outer enclosure, PCB mounting points, internal component clearance, ventilation features, connector openings, and a removable top cover.

The goal was to create a clear mechanical design that brings the electronic components and enclosure together in a structured 3D CAD assembly.

The enclosure needed to accommodate multiple electronic components within a compact footprint while allowing access to external connections and maintaining a clean housing layout.

Key design considerations included:

PCB positioning and mounting support

Internal component placement and clearance

Enclosure dimensions and overall proportions

Ventilation openings and connector access

Screw locations and housing assembly

Top cover and bottom housing integration

I developed the enclosure using SolidWorks, focusing on the relationship between the PCB, internal components, mounting features, and external housing.

The work included:

Development of the top cover and bottom housing with attention to the overall shape, enclosure proportions, mounting locations, and external openings.

Positioning the PCB within the enclosure and arranging the internal components to demonstrate their fit and relationship with the housing.

Creating an assembled CAD model showing the relationship between the enclosure, PCB, standoffs, mounting hardware, and cover.

Preparing exploded visualizations to communicate how the individual enclosure components fit together and how the assembly is organized.

Creating supporting CAD views, including orthographic views, dimensions, section details, and assembly references.

Reviewing enclosure features such as wall thickness, mounting points, ventilation, draft angles, and part geometry with injection molding and 3D printing considerations in mind.

The project produced a detailed 3D CAD representation of an electronics enclosure, showing how the PCB and internal components are organized within the housing.

The resulting design documentation communicates the enclosure structure, component arrangement, assembly relationships, and key mechanical features for further prototype development and manufacturing review.
