40 DESIGN007 MAGAZINE I NOVEMBER 2023 It makes sense to optimize your board using design for manufacturability (DFM) tech- niques, but applying DFM best practices can be confusing without formal training. e results are designs that are oen incomplete, poorly designed, or too complex. When these issues arise, your PCB manufac- turing partner rejecting the design can be con- sidered a best-case scenario because it means they have your back. If your design is simply dropped into an automated queue without concern for manufacturability, the output can be a batch of unusable boards. Expensive mistakes can be avoided by adopt- ing practices that encourage design for manu- facturability. In addition, carefully choosing a manufacturing partner and service level that align with your needs will help you achieve a quality result. Let us examine some design best practices that will help reduce costs, increase yield, and improve manufacturability.
