Note: The following design standards refer to the IPC-SM-782A standard and the design of some famous Japanese design manufacturers and some better design solutions accumulated in the manufacturing experience. For your reference and use (the general idea of pad design: CHIP pieces of standard size, according to the size specifications to give a pad design standards; size is not standard, according to its material number to give a pad design standards. IC, connector components in accordance with the material number or specifications grouped to give a design standard.) To reduce design problems to the actual production of many problems.
