Factors to consider when designing electronic enclosures

Various factors should be considered when designing electronic enclosures I.e.;

Product Requirements

Product requirements refer to the features, functions, and behavioural patterns that a product (in this case electronic product) should have. This information is usually contained in the special document known as the product requirement document (PRD) and is read by people so that they understand how the product will function.

This information will help create a model for electronic enclosures that complements and fulfils the enclosure requirements. In the PRD of an electronic product common functions that may require the design of an enclosure may include the need to reflect heat, prevent moisture, absorb vibrations, LED visible, and accommodate the fan. If this information can be obtained from the PRD, the designer is expected to know what material to use for the enclosure, the associated costs, the suitable manufacturing process, etc.

Modelling the Internal Components

To come up with an ideal enclosure the designer needs to have in-depth knowledge of how the components inside the enclosure will be arranged. This starts with understanding circuit designing and electronic design. Where there is a need for holes, they should be drilled, where there is a need for heat absorption spaces should be left for air circulation or heat-absorbing components.

Some components cannot be placed next to each other in an electronic circuit for many reasons, resulting in false readings, short circuits, melting, shortened life spans, etc. All this information should be a consideration and for the best results, professionals should be hired.

Types of Electronic Enclosures

Electronic enclosures can be classified according to the material type and application.

Classification According to Material Type

The common material types used for fabricating electronic enclosures are metals and plastics, hence the names metal enclosures and plastic enclosures.

Metal Enclosures

In many buildings, there are enclosures made with metals that are used in equipment such as fuse boxes, meter boxes, etc. They are called metal enclosures and are used to protect components from accident impacts and prevent them from contaminations like dust, dirt, and other hazardous conditions. Metal enclosures are often used where portability is not an important consideration.

For industrial purposes, metal enclosures are used to provide an effective and safe working environment for the equipment. There is a lot of dirt and debris produced in industries and these enclosures save well in such instances because metals are stronger and can withstand hard conditions that are in many industries.

Stainless Steel Enclosures

Stainless steel is an alloy of iron, chromium, and sometimes nickel and is resistant to corrosion. Researchers consider stainless steel as a “green material” and it is recyclable. They are used to protect and contain electronic components for outdoor and indoor applications. They have similar designs and production methods except for other differences like density, corrosion, cost, etc.

Plastic Enclosures

Plastic enclosures refer to a container that is used to protect or house electronic components. These are usually moulded in various shapes according to the product requirements. Besides their flexibility, plastic materials are lightweight and can be used to design portable devices.

In cases where insulation is required, plastic enclosures are usually the best to use. Common examples of plastic enclosures are found in calculators, remote controls, desktop computers, laptop computers, wireless internet controllers, coolers, game controllers, and televisions.
