Hi Neil, In IPC-6012A, page 9 table 3-6, states that "Separation along the vertical edge of external land(s)" is "Allowed (See figure 3-3) provided it does not extend beyond the vertical edge of the external copper foil." I think that would mean that this is acceptable. Alain Savard, B.Sc.

Figure 3.2 of IPC6012 (page 12) shows the condition. Having read IPC-6012 and IPC600 I am confused as to the acceptability of this. I would appreciate any comments or an offer from someone for me to send them microsection photographs by e-mail direct (I understand the TechNet automatically removes attachments.
