Don't know if I'm the first to try one of Mark's PCB layouts but the EA Trem came out really nicely.  I won't have time to populate it this weekend as the family and I are winging our way to Seattle but wanted to publicly thank Mark for the layout and the PM help as well.  Here's a picture of the board (and also Will Ferrell, I have to put Elf on the Ipod for the trip).  Nice and roomy and nice wide traces. Thanks Mark!



P.S. This was another successful Photo Paper board.

Looks really good.  Clean traces.  Good luck with the build.

Good job on a good looking layout!

Let us know how it sounds!

markm

Look very good Hiwatt!!
Thanks for the pat on the back.....I needed it today  :icon_biggrin:
Good luck with it and let us know the progress.
Oh yeah, Enjoy the Vacation too!!

is that copper left in the drill holes?  is that something that using the photopaper caused?  just curious, because drilling through that copper could be really tough on the small drill bits.  looks good otherwise.

Where can I find this layout?

Looks like a nice one!

how can i get correct scaling from mark's layouts? 

markm

Well,
As of right now it's kind of trial and error printing through a program such as Paint etc.
I've added board dimensions to my newest layouts but the old ones still have no dimensions.  :(
If there's one in particular you want the dimensions for, let me know and I'll measure the boar for you.  :)

Sorry to reply late on this choklitlove, been in the air a lot over the last 24 hours but to answer your question, yep some of the pads still have copper in them.  Mostly because I'm too lazy to rub off the little bits off paper that stick in them after I soak of the photo paper.  I use teryiaki skewers to remove any paper that remains on the board and I never have the patients to do all the pads too.

But the good news is that the copper has never been a problem.  I've been usings bits I purchased from Drill Bit City (they have a Yahoo storefront) and they get through the copper without a moments hesitation.  I bought two sets of ten bits in two of the common sizes and I've only used one bit and it shows no sign of dulling even after a half dozen boards.  They come in a nice case and each bit has a collar on it with it's size for easy identification.  Also, the the shanks are of a greater diameter so using them in my press is a piece of cake. 

There you have it.  A looong answer to a short question.

Hiwatt,

- Just before you start ironing, you can punch holes through the paper with an exacto knife or needle. Punch on toner side as much as you want in the tonerless areas. This will let the air out that might come between toner and copper during ironing. Also when soaking afterwards, air will want to escape from underneath the photo paper as you might have noticed. This is a big problem, but no issue at all if you've punched the transfer.

- Today I tried to do a transfer with photo paper for inkt jet printers. Guess what? No more rubbing off that last paper film, the whole paper comes off with soaking it in hot water!

- I copied a sheet on the paper and then fed it back into the copier. Worked great, fat traces. Noticed that they are more aligned towards the top corner than anywhere else.

good luck with the next steps, but do try out that "punch the transfer" method next time

Who is that in the background? You? Kinda looks like that guy from Talledega Nights and SNL Will Farrell :) I mean that in a good way of course.

Oh....okay.
I didn't see either movie.....I gues I need to get out more huh?  ;D

BTW,
I'd like to say Thanks to MarkM as well     :D

Lol, I bet that whales vagina looked pretty odd if you weren't getting it.  ;)

I still can't get this darn thing resized!  Using paint (the only picture editing program on my PC, the only computer that hooks up to my laser printer) I lose too much clarity for it to work...
How on earth did you manage to resize this!?



Hiwatt25

I just opened it with the Adobe photo viewer utility.  I don't recall exactly what it's called but it's available for free download over at adobe. 

I scaled it down by 49% and it was dead nuts at 2 inches.  However, I scaled down using my printers software package so all printers may not allow for that. 

I saved Mark's layout, opened it with adobe and clicked print.  When the printer options box popped up, I selected advanced options and chose the "scaling" option.  I printed a few different test sheets till I got it right and finally settled on 49%. Works great. 

BTW the laser printer I use can be found at newegg.  I'm not at home but I can put the model number up when I get home.  It was $100 with a $50 rebate and has worked really well thus far. 

Hope that helps.

Just bumping this in case rockgardenlove didn't see my reply before it slipped to page 2.
