Express PCB Land Patterns

AlecS

Hi All,

This is my first time posting here, althought I have been stalking the forums for some time now.
Firstly, the prop looks great! I have been programming PIC Mirco's for robot's as a hobby for quite a while but after seeing the prop I don't know if I can use PIC's any more!

I was wondering if anyone had a few ExpressPCB Land Patterns (.p files I believe?) and .SCH files. I need this huuuuuge list of land patterns...well not THAT huge...

1) Prop LQFP . I downloaded one which was posted a while ago but it said it was created in a newer version of ExpressPCB even though I have the latest
2) 24LC256/512 SOIC (I Think thats the same as is on the new proto board is it not?)
3) LM1806 Voltage Regulator TO263.

Thanks in advance

Alec

Alec,

There is a library for the prop on the Eagle site, not sure about ExpressPCB yet.

The footprint for the Prop LQFP is in the Express Lubrary - SMT QFP|
44 pin.

Hi Guys,

Ok thanks for the eply I Thought it might be a little differnet for some reason.
What about the other 2?

Are they standard packages also?

Thanks,

Alec

The dip is a standard 0.6" wide 40 pin DIP package. I don't know if expressPCB has the QFN part, but that package is not meant to be used by a hobbyist, it requires reflow to solder it to a board which most hobbyists don't want to deal with.

Hi All,

Thanks for the reply's. I didn't even know about Eagle!
Giving it a go, looks good so far

Paul, Im not even going to attempt QFN despite the tiny size!

Thanks for the info.
