How to Select Components Based on Packaging
PCB packaging is actually to display various parameters (such as size, length and width, pad size, etc.) of components and chips in a graphical way, so that they can be invoked when drawing PCB drawings. So before the design of PCB, the choice of components becomes the most important. Otherwise, there will always be some problems in the design, which will lead you to spend a lot of time designing PCB boards that can never be used in practice.
