IPC-7351 Padstack Naming Convention

Cheers Tom,

So now I am being told your document should be changed as it is your document that is saying that they should be the same shape as on the outer layers.
Which is contrary to both what you have explained and that the 2nd item suggests.

They are either matching the outer layer shape or they are round.

Inner Layer Land is the same shape as the outer layer land
contradicts:
The inner layer land shapes are Circular
Because if the outer layer land is square and the inner layer land is the same shape as per the first default then it cannot be round as per the 2nd default.

What is being suggested is that your statements in that are conflicting & hence confusing - perhaps the first one should not be used?

I have someone asking a question about this.

• Inner Layer Land is the same shape as the outer layer land
• The inner layer land shapes are Circular

These 2 statements are conflicting with each other, how can the inner layer land shape be the same as the outer layer if it has to be circular ? The outer layer land shape could be square.

To me it's obvious, the inner layer lands are always the same shape as the outer layer lands unless you deliberately change them to be something else, the default shape (unless there are overriding factors that require otherwise) is for the inner layer land to be circular.
But it does not read as I have written it - it just reads conflicting. :)

Any suggestions for naming multi-drill padstacks?

I'm looking at 2013.12 and it looks like it was't fixed.

Once Jeff gets back from vacation in a week, we'll fix this padstack naming convention to match IPC-7351.
