Gainclone PCB suggestions

Jaycee,

I am referring to the toner transfer method. After looking at a few different methods....it seems to be the most cost effective (and easier) one around.

I have been looking at eagle for a couple of days and it does not seem to hard to learn...I am hoping that there is library with the a good set of national chips (I can't seem to get the pin spacing just right).

Anyway, I am hoping to have some type of prototype drawing done by tonight....or if anyone of you have some Eagle "templates" that you could send me via e-mail...please feel free. My address is wboyd (at) iglou (dot) com.

Thanks,

Wayne

I've had a chance now to play wioth diptrace. My initial thoughts are positive. It seems easier to use, the library seems better, and the lm chips are supported. Looking at the instructions it seems to mate with lt spice. Have not tried this yet.

Certainly joining parts on the schematic is less hit and miss for me. This bit is much easier.

Eagle isn't that hard to learn and does come with a decent library of parts. As you become more proficient with Eagle (or any other software) you'll find yourself wanting to create your own footprints and symbols, so it is definitely good to learn how to make your own.

Ok...I am sort of getting the hang of eagle....here's a question...probably a simple answer....but how do I designate the size of the board?

 

[jaycee]

by the outline on the "Dimension" layer. Just draw a square from lines on this layer. It's usuallly best to use "0" width for that.

Ok....the more that I play with it....the more it frustrates me - hahahaha. No, seriously, I seem to be getting the hang of it...slowly but surely....

Keep your ideas/encouragements coming....soon enough I will have a basic PCB!

Have a good one,

Wayne

It does seem daunting at first (any PCB package does really) but once you have the hang of it, you really wonder how you managed without

My first go at chipamp PCB

I would like some feedback on my first LM3886 PCB.

There are several things that I am well aware of, but consider a neccesary tradeoff. If someone thinks otherwise or have got a brilliant solution I'd like their input.
1 - Signal input runs along negative supply for a good bit
2 - Decoupling caps are quite far away from their ICpins

This is because I will mount the IC with a clamp that runs straight infront of it.

An externally hosted image should be here but it was not working when we last tested it.

Looks good What method did you use to transfer the layout to the board?
