Default Another LM3886 PCB!!

Hi All-

I am working on another LM3886 PCB but this PCB needs to be as narrow as possible. I am hoping to make the PCB just slightly wider than the actual chip. I will be using "smallish" caps on the PCB and additional caps on the pwr supply board. Also components on both sides as needed to help minimize the size.

What I am requesting in this thread (so we can kill it quickly) is for someone's file from ExpressPCB or Eagle that I can use for the LM3886 mounting holes.

They are NOT the standard .100 spacing, and I am not having any luck making my own from scratch.

Any assistance would be appreciated.


Thank you in advance,

Troy

Edit: Email address might be nice... stgrab@yahoo.com

They are 0.134 center to center. National's pdf on 3886 has all the packaging dims , but the spacing across has to de deduced. Treat it as .135 and set your snap grid to 5 mils.

I emailed you an lm&opa.zip file that contains the package that you need. I downloaded it off the forum several months ago, so the credit goes to whomever made it available at the time.

cheers

Thanks Ray-

I did some searches for it, as I also remember someone posting it, but came up with pages of hits. I'm still going through them.


Thanks again,

Troy

Hey neutron7-

Then you make it and sell me some boards... I'm impartial... Just need a narrow PBC.


Thanks,
