The cutting edge of machining
electronic device housings By Del Williams, US-based technical author

eyond the semiconductor components themselves, today’s electronics products need to be enclosed and packaged in consumer- usable forms, oſten
machined from various specialty metals and alloys. Te reality is that a failure in an electronic package or a non-semiconductor component can be just as catastrophic as a semiconductor failure. Given the critical nature of these
components, the cutting edge of machining now goes far beyond the latest CNC equipment and accessories. It also means engaging at the earliest stages of the process, using the latest in Design-for-Manufacturing

(DFM) simulation and process verification processes prior to cutting the first part. It is then critically important to have flexibility and adaptability to make changes and scale production when needed, with the ability and commitment to inspect with the most precise tools throughout the process. Te goal of this approach is to give customers the assurance that when machining begins, the parts will be 100% right, with zero defects, the first time and every time. Typically, when a potential customer
searches for a machine shop to make a complex electronic device housing or part, they are looking for the latest equipment and current certifications, including ASQ, ISO 9001 and AS9100. It’s a tremendous benefit,
however, for a customer to look beyond these prerequisites for a machine shop that will work with them from the design phases through manufacturing, to predict and resolve failures before they happen.
Design for Manufacturing A DFM process enables the machine shop to anticipate upfront possible complications and limitations in the machining process. “With Design for Manufacturing, the goal
is to make the product manufacturable in an efficient and cost-effective way, and that starts with reviewing the parts and discussing the specifications openly,” said Tony Doan, CEO of San Jose, California-based Halcyon Manufacturing, an advanced ITAR-registered
