How to manufacture electronics components

These are the steps involved in manufacturing electronics, as well as recommended technologies and materials used to create them.

Whether it’s a prototype, housing for sensitive components, or a mechanical component, parts for electronics must meet stringent quality and performance standards. To ensure they do so, you must take a meticulous approach to their manufacture – one which encompasses materials, design, and production methods. In this article, we’ll take a look at all of the above, so you can make informed decisions about manufacturing parts for electronics. 

Types of parts commonly manufactured for electronics 

The types of parts you’ll need for electronics will of course depend on the product. However, the following parts are those that we often see our clients manufacture. 

  • Metal enclosures. Aluminum and steel enclosures serve as protective shells for electronic devices like industrial control systems, server racks, and scientific instruments, shielding internal components from external elements.

  • Battery housings. Battery compartments are precision-engineered to accommodate rechargeable and non-rechargeable batteries in various electronic applications, such as medical equipment, remote monitoring devices, and instrumentation, providing convenient power solutions.

 Manufacturing methods for electronics

Manufacturing methods for parts for electronics encompasses a spectrum of techniques, from injection molding to 3D printing to sheet metal fabrication. The right method for your use case should be chosen based on the final application for your part.

  • Die-casting. Die-casting is employed to create metal parts with intricate shapes, such as aluminum or zinc alloy enclosures. Molten metal is injected into a mold, cooled, and then removed, resulting in highly detailed and durable components. It is a good choice for producing complex electronic components like heat sinks or lightweight yet durable aluminum alloy casings with intricate designs and fine details, such as those used for smartphones or tablets.

 Selecting materials for parts for electronics

When selecting a material, you should consider several factors regarding the nature of the electronic your part is meant for. These factors will vary depending on the application, but here are a few important – if not universal – ones. 

  • Functionality. Ensure the material meets the functional requirements of the part, such as electrical conductivity, insulation, heat resistance, or mechanical strength.

  • Durability. Consider the material's ability to withstand wear and tear, impacts, and environmental conditions relevant to the device's use.

  • Weight. Choose a material that balances the need for strength with the desire for lightweight components, especially for portable devices.

  • Cost. Material cost can significantly impact production expenses, so balance material performance with budget constraints.

  • Manufacturability. Assess whether the chosen material is compatible with the manufacturing processes needed to produce the part efficiently.

  • Heat dissipation. Determine if the material can dissipate heat effectively, which is crucial for components exposed to heat-generating electronics.

  • Dimensional stability. Choose materials that maintain their shape and dimensions under varying temperature and humidity conditions.

  • Aesthetics. The material's appearance and finish should align with the device's design and user expectations.

The exact material you need will also depend on the part’s intended application. However, we often see our clients use the following to create parts for electronics.

  • Aluminum. Aluminum is favored for its lightweight yet sturdy properties. It's commonly used for casings, heat sinks, and structural components in laptops, smartphones, and audio equipment. It offers excellent heat dissipation and a sleek appearance.

  • Steel. Steel, especially stainless steel, is employed for durable and corrosion-resistant components in electronics, including structural elements, fasteners, and hinges.

  • Silicone. Silicone rubber is valued for its flexibility, heat resistance, and electrical insulating properties. It is used in electronics for sealing, shock absorption, and as a protective covering for cables and connectors.

  • Carbon fiber. Carbon fiber composites are employed for their exceptional strength-to-weight ratio and resistance to electromagnetic interference (EMI). They are used in high-end or hard-working electronics for structural reinforcement and EMI shielding.

Surface finishes for parts for electronics

Surface finishes can provide parts with enhanced aesthetics, durability, and functionality. Here are five commonly used surface finishes, with examples of how they could be used in electronics-related applications.

  • Electroplating. Electroplated coatings like gold or chrome enhance the conductivity and appearance of connectors, switches, and buttons in various electronic systems, including telecommunications equipment and automotive electronics.

Design for manufacturability for electronics

Design for manufacturability (DFM) is a critical aspect of creating efficient and cost-effective parts for electronics. Optimizing designs can streamline production processes and improve overall product quality. Our built-in DFM analysis considers these aspects of your part:

  • Simplicity. Minimize complexity to reduce manufacturing errors and costs.

  • Tolerances. Specify tolerances that balance precision with cost-effective manufacturing.

  • Assembly. Design parts that are easy to assemble, reducing labor and time.

  • Standardization. Use standardized components to simplify sourcing and reduce costs.

  • Testability. Incorporate features that ease quality control and testing during production.

Part consolidation. Combine multiple components into single parts where feasible, simplifying assembly and reducing the number of required parts.
