Thankyou Roger,
"Oh no, its all in Metric, how will we cope" lol.
I can see some annotating it to the Imperial that they are used to.
Where it refers to IPC-782 I take it that the details will actually be
included in the std
but its going to be the same as 782?
It would seem daft to have to refer to 2 stds.
The 3 complexity levels bit, is that sort of meaning:
1. Very tightly spaced board - components virtually on top of each other,
2. Average spacing on board, room around components.
3. Loads of room on this board, the components will need binocs to see each
other.
Or am I confusing this with something else?
For the "Mounting holes", what does #3 "Available with 8 via holes" mean?
Does this mean that they can have 8 vias around them for PTH connecting?
Matthew.

Matt,
To get a preview of what seems to be coming up in 7351, check out this link:
http://www.pcblibraries.com/downloads/files/GENDoc-Lib_LandPatternDesc.zip
It also appears that 7351 will be a family of specs, from 7351 to 7359, the
first 8 docs similar/equivalent to IEC 61188-5-n.
I thinks I may ask for a draft from John P...

Oh well, so that means possibly another change to my libraries just to try
them out.
I hope the range of parts has dramatically increased too.
There doesn't seem much point in me getting the 2nd update to 782 (just
noticed it) now does there :)
Can anyone enlighten me what its all about? (IPC-782A-AMEN that is) as no
doubt I will still be using
that spec pads for a while yet (change is a slow beast).
Matthew.
