John,
I heartily agree with Richard. One specification arrived with the highlighting and it quickly helped us to understand that solderability test temperature and flux type need to be changed. While we would probably have found this, it would have required a side by side comparison of the documents. The change was clear immediately with the highlighting. I believe that highlighting is a great aid to all IPC document users.

John,
I loudly applaud this practice. I commend you for doing this. It should be standard practice across all of the IPC documents. It does no harm, and can only help highlight the latest updates for those of us who are already familiar with the standard, but want to see what has changed without having to refer to another document.

HI Greg and Bill,
What I have been doing within my design standards (IPC-222X, IPC-7351) and my performance specifications (IPC-601X), is highlight areas of change within a revision with gray-shaded text. If there has been a change to a Figure or Table, then the figure or table header is gray-shaded.
I will include a statement about this within section 1 of the standard, e.g., 1.7, Revision Level Changes, in IPC-6012C.
This was something that my standards committees had asked of me awhile back, and it has been met with positive responses since.
This is NOT a universal IPC procedure. There are other IPC standard development liaisons within IPC that DO NOT utilize this approach within revisions of standards they are responsible. I myself was trying to be responsive to those who develop and use the standards I am responsible for.
I hope this helps!
Regards,
John Perry

I am new at most of this. But as it was explained to me the grey areas represent those items changed from the previous revision.
John Perry may want to add some comments on this.

Hello all - Where in our collection of IPC Standards does it define what is intended by the highlighted text (much of the text has a grayed background behind it) in many of the newer standards? I'm assuming this is to indicate a change from previous revisions but I cannot confirm where it states this. Thanks in advance.
