Why Early DFM for SMT Assembly Matters in Quick-Turn Prototypes
In real manufacturing situations, prototype PCB Assembly is hardly clean and predictable. Designs come with short time lines, changing requirements, and demands that the initial build should simply work. A prototype means more than just assembly of boards; to a manufacturer, it means the identification of risks early in the process, the safeguarding of a schedule, and the ability of a design to proceed without the need to go back to the drawing board and pay a lot of money. Where Prototype Builds Actually Break Down The most typical problems in low-volume prototype PCB Assembly are not catastrophic problems, but rather minor, cumulative problems. Wrong footprints, inadequate polarity markings, and peripheral solder pad layouts slacken assembly much more than the designers anticipated. Part availability is also a common problem. Ideal components that are available or constrained without notice are usually used to design prototypes. A producer will have to choose what to do with the alt...
