WebThe IPC-7351 refers to the set dimensions you must use to create a land pattern essential for PCB footprints. These dimensions include: pad spacing (labeled as G), the pad width (labeled X), the pad end to end dimension (labeled Z). They will help in the accommodation of component spacing, thereby preventing solder defects.
