What defines box build assembly?

A box build can be defined as an enclosure of electronics. They are often customised to the needs of the user, and have different levels of complexity, depending on the customer and their requirements for the product.

Box build assembly consist of both design, production, and construction.

In short, box build consists of 3 elements: printed circuit board assembly (PCBA), mechanical components, and cables. Every part - from component to assembly - of the product is most often customer-based, meaning that the box build is assembled according to drawings and instructions from the customer.

Printed circuit board assembly (PCBA)

PCBA is a fundamental process in electronics manufacturing. This part is what connects all the electric components and mechanically support the box build. The PCB assembly involves assembling various electronic components onto a printed circuit board to create functional devices.

PCBA for a box build

These components, including microchips, resistors, capacitors, and connectors, are carefully placed and soldered onto the board using advanced machinery and skilled labour.

PCBA is a critical step in the production of the box build, as it determines the device's functionality and performance. The precise arrangement and secure soldering of components ensure proper electrical connections, signal integrity, and overall reliability.

PCBA combines design, engineering, and manufacturing expertise. The efficiency and accuracy of the PCBA process significantly impact the quality and functionality of the final product, making it an essential aspect of box build assembly and modern electronics production.

Mechanical components

The enclosure is a key mechanical component in a box build assembly, serving as the protective shell that houses and shields the internal electronic components. Designed with precision, the enclosure ensures both functional integrity and physical protection for the box build.

Manufactured from durable materials such as metal or high-quality plastics, the enclosure provides robust defence against environmental factors, physical stress, and potential electromagnetic interference. Its design factors in ventilation and heat dissipation to maintain optimal operating conditions for the enclosed electronics.

Beyond safeguarding the internal components, the enclosure often includes openings for input/output interfaces, buttons, displays, and connectors. These allow users to interact with the device seamlessly.

Its aesthetic design can also play a role in the product's overall appeal, aligning with company branding and user preferences.


The cables are carefully designed to meet the requirements of the box build regarding data transmitting, signals, and electricity. They play a critical role in the functionality and operation of the assembly.

Cables are meticulously selected based on factors such as data transfer speed, power requirements, and environmental conditions. They are often shielded or insulated to prevent interference, ensuring optimal signal quality.

Whether transmitting information between circuit boards, connecting peripheral devices, or supplying power to various modules, cables are the element that keeps the components working in harmony.

A prober arrangement and management of cables within the box build also contribute to the device's overall efficiency and aesthetics. Efficient cable routing minimises clutter, enhances airflow for cooling, and simplifies maintenance and troubleshooting.

A strategic placement of connectors and cable ties ensures a clean and organized internal layout.
