Subject: Supported & Unsupported holes
Fellow TechNetters:
Is it safe to stated that a SUPPORTED hole contains a plated through BARREL and an UNSUPPORTED holes does not contain a plated through BARREL... I am measuring the hole break out on an external PTH annular ring. IPC-2221 Figure 9-2 & Table 9-2.
Victor,
