In addition, we have provided a few tips on how to implement better DFM practices in order to prevent these types of issues from occurring in the future. Read on to learn more about each type of problem and what you can do to fix them in your initial design. To help narrow it down, we have outlined ten commom DFM issues for you to reference. Knowing where to start in the vast array of PCB challenges is half the battle. Recognizing roadblocks is a way to gain better insight in designing a better workflow in future projects.Ĥ THE ISSUES A COMPREHENSIVE LIST There are numerous challenges to face when running DFM checks. How do we break this cycle? The first step is to get a good understanding of the common DFM issues that plague design teams again and again. DFM issues are all too common from reduced yields to missed time-to-market schedules, the blowback from such a failure can be detrimental in a competitive market. Eventually, your board will be accepted, but not before your department has spent a significant amount of time, money, and man-power. This can happen several times with multiple iterations, causing massive delays. Once there, the manufacturer finds issues with the board and you are forced to go back into the layout process to solve them. The design department has gone through the phases of design intent, layout, manufacturing data, and is now into review. Good DFM will keep your projects on schedule, prevent late-stage changes, and keep build costs predictable.ģ THE EFFECT OF DFM PROBLEMS Typically, most issues are found much too far down the pipeline. Simply put, when you design to your ending specs at the source, your company will greatly increase its productivity. DFM is the basic practice of designing a product with the end (manufacturing) in mind, helping entire design process go as smoothly as possible with little to no surprises. This scenario happens all too often, and this is why it s important to Design for Manufacture (better known as DFM). You re stuck back to the drawing board, no closer to a finished piece than before and worse yet you are already weeks down the line.
You are relieved when it gets sent off to be manufactured, but become frustrated when certain parameters have severe violations. We ve all been there: you create a great design that should be watertight. From layout to manufacture and testing, a single holdup can cost a business untold amounts in lost productivity. 1 TEN COMMON DFM ISSUES AND HOW TO FIX THEMĢ THE IMPACT OF AN INTERRUPTED DESIGN FLOW Every day is busy for PCB designers strict schedules and tight deadlines are a normal occurrence.
