Dear TechNetters: Can anyone point me in the direction of a standard/reference that defines tolerance for PCB size (length and width)? The -2221, Fig. 5-1, shows ± 0.016". This seems quite generous but I can find nothing else. Thanks in advance - Bob Lazzara ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
