Box building in the context of electronics manufacturing refers to the process of assembling a complete, functional electronic system or product, it involves not just the assembly of the printed circuit board (PCB), but also the integration of this board within its final enclosure along with all the necessary components and interfaces. Box building consists of the following steps:

• PCB Assembly: The core of the product, the PCB, is assembled first. It includes surface mount technology (SMT), through-hole technology (THT), or a mix of both.
• Wiring and Cabling: Connect the PCB to other components within the box, such as displays, power sources, or additional modules.
• Installation of Components: This includes mounting various hardware components like switches, connectors, displays, and other peripherals that are part of the final product.
• System Integration: Bringing together all the electronic, mechanical, and software components into a cohesive, functioning whole.
• Enclosure Assembly: The PCB and all other components are then housed in an enclosure, which is made was metal.
• Testing and Quality Assurance: The assembled product undergoes rigorous testing to ensure it meets all functional, quality, and safety standards.
• Software Loading and Configuration: If the product includes software or firmware, this step involves installing and configuring it to ensure proper operation.
