25 Some Items to Consider F F Examine all the constraints at the start of a design project before ever starting the layout. F F Acknowledge that what goes into a parts list will influence availability, size, shape, and performance. F F Determine what information will be included as the project is captured into schematic form. F F Evaluate PCB size and shape requirements—before the layout begins is the best time to get in touch with a good PCB fabrication supplier. What is the intended size and shape of the PCB? F F Raw materials for PCB fabrication are stocked in sheet form by the supplier. A designer needs to know if the available material can accommodate the PCB outline. F F Consider the parts placement and how a single design placement influences thousands of parts and operations. F F Recognize the need for testability. How the assemblies will be tested. Bed-of-nails or functional test, etc. F F Keep in mind the customer's desire for timely delivery, quality, and good price. All customer needs will be met in the end if all stakeholder needs are met before and during the project. F F Scrutinize your process. Things will go wrong. If you have a process in place, it will be easy to point to where a problem occurs and fix it so it doesn't happen again.
