Design of electronic boxes

Good electronics enclosure design will ensure the long-term success of your electronics project. Careful planning and testing must be included in the design of any industrial electronics package.

1. Getting the right size
2. Using the right materials
3. Respecting the transmission of signals
4. Check the layout of the components
5. Ensure compatibility with the BOM components

Getting the right size

It is important at this stage to ensure that the electronics box will fulfil the safety and functionality functions at the expected cost.

Choose the most suitable material for the product

For indoor or outdoor use, "premium" or "entry-level", the box will not meet the same specifications and will not have the same budget in terms of materials used.
Thermoplastics allow a freedom of form not achievable with steel housings. In addition, outdoor use will be facilitated, due to the absence of corrosion.

When it comes to the choice of material, use and environment are the key words:

• Indoor or outdoor (UV resistant)
• Underwater or under the ground (waterproofing to be respected: IP65, IP68, IP44)
• Temperature extremes
• High humidity
• Mechanical stress
• Vibrational behaviour

Ensuring the transmission of signals

Thermoplastic cases are better able to pass bluetooth or wifi (wireless) signals than metal cases.

It is also possible to choose materials with electromagnetic radiation shielding.

Design is not everything

The positioning of the components on the PCB must also be taken into account when designing the enclosure. Also, the support areas, openings for connectors and ventilation areas must be positioned appropriately, according to the product specifications.

Your customer will ask for a compact, aesthetic case, no problem! But a non-functional box will not bring satisfaction if the PCB is not used in an optimal configuration.

Compare the 3D design of the card with the BOM!

unfortunately, it often happens that the 3D PCB file does not match 100% with the BOM of the gerber file. a little extra space is never superfluous!
