Title: Question for PCB manufacturing
Post by: Alex on December 04, 2007, 23:00:23 PM
This is my first post in this forum and so I first would like to welcome you all.

My question is regarding the manufacturing of a PCB. Ok, I have the e-diagram and the pcb layout. But I want to make it as small as possible and using the permanent pen method this is not possible. I have heard about the photographic method. Does anyone know anything about this?

Thanx guys

Hallo Alex.
Using the photographic method is quite easy and very precise. You will only need one laser monochrome printer, one transparent film to print your PCB (this film must be designed for using with laser printers), a special PCB with a photosensitive layer (can be found almost in any store) and some chemicals.

You can find a detailed description for this method right in our site. Check this link (http://pcbheaven.com/workbench/pcbmaking/)
Search the left side bar for the link Manufacturing PCBs.

Have fun

If you want, you can use self-transfer method to make your pcb directly to the copper. This is also a very precise method and also is easy and fast.

I know this method and I tried it once. I did not get the results that I expected

When I put the PCB to the liquit for etch some stickers went off the PCB and it was all ruined.

Then you should consider buying some better quality stickers. I use it very often and it never fails

Thank you Kostas. I will try the photographic method instead because I use some software for making the PCB and I thing it is much easier when you work with a pc software.

Yes you are right. This method is perfect for using with pc sotware!  ;)

I read your article. It is great! I test it already. Thanks Kam! Keep up the good work!

Kam this method with toner transfer.. does it work? Have you test it? It seems a little bit strange. And very easy and cheap to be true.

Of course it works. You can try it. Needs a little bit try and error but you will get some good results. After all, you will not need to destroy boards (as may happen with photographic method if youdo something wrong). If you have no good transfer, clean with acetone and restart. It is that easy  :) :)

Now when you say "magazine paper" on your article, what exactly do you mean? Blank magazine paper?

Of course not blank magazine paper. Magazines are 99% copied using offset method. This method does not use toner like ink. The ink of the offset method is permanent and does not transfer using an iron.

When i say magazine paper i mean, you buy a good magazine for 5 euros and you have let's say... 100 pages for test. 0.05 euros per page. good eh?  ;)

Wouldn't photographic paper be better? have you test it?

Well, the problem will be when you try to remove it. It will not get sog and it will torture you until it is completely off. You need something like, ehm... magazine paper (  :P :P)

There are also special pill out papers for this reason. Really easy to use as i see. But everyone says that it does not worth the price as with plain paper or even magazine paper it works also good.

And of course your trick with the etch-rub is really neatly!
