You mean like this sort of thing? : http://www.gigadyne.co.uk/image001.jpg

Pumps out fully toleranced Allegro scripts with a few enhancements to 7351,
probe keepouts, fiducials, silkscreen and resist
placement etc. Once the 6 to 15 package parameters are entered and checked,
there stored in the spreadsheet. Real easy to create
new libraries with changed environments. Takes a few minutes to build a few
hundred parts.

Best Regards

Ah, I see what you mean...real pickle, eh?

Never had to print the output, I would just generate what I needed
side-by-side on the monitor.

Could just purchase the librarian for, what, around £270, direct from the
software house? Unless of course Dynamix has rights to
sell it in the UK, then probably more...then print screen.

Call me silly (everybody else does), but couldn't we just take the formulas
and numbers from the 7351 standard and just plug
them into the 782 calculator that is in Excel(tm) format?  Or else create a
basic spreadsheet that would do the job for you?
Wait, that's what George suggested...Hmmmm.

Or else wait on the "free" online version...

Devil's in the details, eh?

Happy Friday,
Roger "right smack dab in the middle" Stoops

(I can't complain, I have the LP Calculator that does okay for me.  Also
have the old 782 spreadsheet.  And one of our EMS
providers has their own land pattern requirements.  As long as my handlers
are happy, I'm happy...)

Subject: RE: [DC] Propaganda Rant & IPC-7351

I asked if there was a single user license that would allow me to print out
what I see.
That's all I want, a single PC with it on & the ability to print out the
dimension info to be able to make the footprint on the
same PC.

There is not.

It's a site license with the librarian that i'm told I'd need.

No ta.

rant, rant...

Curious...  why would you compare a single user license cost to a site
license cost?  Wouldn't a single user license work as
well as it did before?

Regards,
Roger

Coming quite late into this also...

Having looked on the IPC site for this std, it appears that there is a
document available (that turns out to be remarkably
similar to the front of IPC-SM782A) and that the footprint dimension info
itself is only available from the LP viewer.

I have just installed the latest version of the LP viewer.

Yes it looks good, has many components in, even SMT electrolytic caps which
I would find useful.

However, I am unable to print out the dimensions that I see on screen.
I used to be able to do that with the online 782 calculator. :(

OK, fair do's I think, what if I get my employers to purchase the std &
perhaps the next level of the program that will allow me
to print it.

So I ring up Dynamix, a UK supplier of IPC stuff.

It would appear that I would be paying £2161.80+vat for a site license for
this.

WTF!

Why has this gone from a £90 std (non members cost) to well over 2 grand?
This is ridiculous, I can certainly see that I will certainly NOT be using
this std over the 782 no matter what Nick says the
improvements are.
