Hello TechNet,
For those who are familiar with IPC-2221 and IPC-2222 standards : what are
the recommended clearances between a PTV/PTH and an internal PCB ground
plane?
IPC-2222 §9.1.3 'Clearance area in plane' includes a picture with an 'A+B'
distance corresponding to the summation of the electrical clearance and the
manufacturing tolerances, but I cannot find any numerical values.
Can somebody help?
I am primarily interested in the case of an unsupported hole without NFP in a
ground plane.
Thanks in advance for your insights.
Best regards,
A. Grivon
