The Basics of a Complete System Build

Electro-mechanical box builds and complete system builds are almost an essential part of EMS setup. As assemblies grow more complex, standards more stringent, customer service and value for money become the key drivers in the new economy.

The days where a printed circuit board (PCB) assembly firm would collaborate with a rack and harness manufacturer as well as a cable and assemblage firm have come to an end. Outsourcing to man vendors for a single product leaves the customer with a host of complexities and potential errors and functionality issues to deal with before the product can be sent to the end consumer.

A few firms who serve the communications, semiconductor, government, medical, industrial and aerospace industries see value in offering complete system builds—where the product, its core components, circuitry, wiring, assemblage, casing and packaging are all handled by a single electronics service provider. A firm that offers comprehensive solutions is able to cater to a wide range of precision, industrial and commercial applications. Complete system builds also ensure that the expertise for the product’s life-cycle remains in-house or outsourced from a single firm. The benefit is seen by both manufacturers and customers when higher quality products can be assembled for lower costs.

Single Firm: Multiple Products

A single firm which offers a wide range of durable racks and chassis for a system build is positioned to reduce errors and provide a streamline process. Whether for precision medical or aerospace applications or heavy-duty industrial uses, racks ensure the optimal use of space and are available in a range of bracket configurations depending on the scope of use in complete system builds. Aluminum, steel and custom molded enclosures allow for PCBs to be mounted in any desirable configuration, optimizing space, and ensuring safety. Most electrical and electronic enclosures are designed to meet International Protection Rating standards including IP65, IP66 and IP67.

Card cages and card enclosures are essentially frames that support assemblies for PCBs and other electronics as well as their power supplies. A card cage needs to be fabricated to precise dimensions and configuration in order to support its active backplanes and all associated power cables for a variety of form factors. Card cages and enclosures have applications in both electronics and electrical industries from outdoor power supply circuitry enclosures that protect electronic cages for sensitive signal processing and computational purposes from weather and water. Modular enclosures and towers help keep components at optimum temperature and keep wiring compact.

Firms that offer box builds for electrical and electronic installations will need to rise to challenge of keeping builds compact while ensuring a client’s requirements and safety standards are met.  An additional challenge is the planning of builds that are compliant to increasingly stringent standards for electronic and electrical equipment. Choosing an EMS who has the experience and resources to provide a complete system build is essential in the process.
