[IPC-600-6012] IPC-A-600 Revision H Imagery - Pits and Voids






Hi All,

Most of you are familiar with the ongoing effort to resolve comments to 
the Final Draft circulation of IPC-6012C, and while that is nearing 
completion, I want to get started on addressing comments received to the 
Final Draft circulation of IPC-A-600H through this task group e-mail 
forum.

Section 2.2.4 of the IPC-A-600H Final Draft (located at 
http://www.ipc.org/CommitteeDetail.aspx?Committee=7-31A under "Drafts") 
addresses pits and voids in printed board base material.

Figure 224c under "Acceptable - Class 1, 2, 3" is new to Revision H, but 
received a number of comments indicating that the figure is confusing - 
it's not clear what the yellow arrow is pointing to and pits and voids are 
not evident.

Does anyone have a better photograph that shows an acceptable degree of 
pits and voids on a printed board surface?

Thanks,

John Perry
