Nice work and your kitchen looks very clean too. I've made all my pcbs
using Press and Peel Blue for my guitar FX, but haven't tackled the larger boards.
I don't know if you meant this Quote: | Only a few hundred tiny hoes left to be drilled.

yep I know I'm juvenile hehehehe
I want to build the sequencer this winter. Keep me posted on how it goes. _________________ "your stripes are killer bro" |

....it looks like you get excelent results (by doing careful work, no doubt). i have to say, however, that given the hole drilling operation, and the fact that adding legending on the other side is a pain, i've opted for mail order houses when i've needed custom boards.

Hey very good work! I've never used photoresist, I've just did the "iron on" method by printing special paper through a laser printer. But photo resist looks much cleaner, and doesn't seem to need any touch up at all!
Unfortunately, most of the parts I use now have shrunken into TQFP and other surface mount packages, so going to board houses are sometimes the only choice. But I'll have to try out the photoresist next time I play with something like through-hole dips, or maybe even SSOP type packages.
Thanks for the post!
[edit : jk* - I moved this to the How To/Developer's Corner from the SoundLab forum so other's can find this info when making boards!] |

Oops Thanks Zebra for the correction!
About drilling hoLes I must say it is WAY easier than you might think. I would say it took about 20 minutes to do both these boards!
When it comes to legending I've noticed that if you use glass fibre based PCB:s they become semi transparent after the etching. That means you can see the PCB artwork through the board when looking at the component side. If you have the component layout in front of you on paper or on the computer screen, it's easy to find the same place on the board! The same is NOT true if you use PCB:s of the cheaper material that you can't see through. |

Hey gubbeper,
Excellent documentary. Time to be proud indeed! Gotta love that exposure unit Are you using natriumpersulfat (en. spelling?) for the etching there?
It's so cool to make your own PCBs, I've done it some times too. I find the drilling to be the hard part, usually wearing out drill bits really fast, at least on epoxy boards, even using supposedly very tough bits.
Next up is double sided then?

Dr: Thanks! And yes it says Natriumpersulfat on the package. I haven’t tried double sided yet but I don’t think it would be that hard. I read an other article about how to do it and basically you just tape the to negatives together and then, somehow, fix the board in between them. Didn’t look that complicated. Actually one of the boards on the pictures is double sided but the other side is simple enough that I decided to try and wire it by hand.
About drill bits, I’ve bought some, supposedly, professional ones from this guy that I’m eager to try out on the next board. I hope they’ll last a bit longer. - Pun intended |

Natriumpersulfat is nice to work with. When I was a kid we used jernklorid (en. sp. Ferite Chloride ?) - that was extremely messy - everything became rusty red!
I did some double sided boards by drilling guide holes in the board and the films, then using alignment pins through it all to hold it in position. Worked fine. The idea is that the board can then be handled somewhat and the films perhaps applied/reapplied for two single sides exposures etc., with repeatable alignment. But it is simpler and probably just as effective to use the tape method.
Still got a couple of makes of drill bits lying around to try out. Even though the likeliness of using a board house even for hobby projects is on the rise, you never know... might drag out the PCB kit someday just for the fun.

Ops, sorry! The url must have changed when I reinstalled the server some time ago. I changed the original posting to point to the new address so it should work now.

I cannot find this "photoresist" ANYWHERE. I found some pre-treated boards at a local shop, but that won't do. Anyone have anything for me? Or must I use the radioshack marker method?
Also, sources for copper clad boards would be MUCH appreciated.
Thanks to all! |

does anyone of you (germans/german speaking) know the german name for "photoresist" and where to get it (all those chemicals in general)?
cool and very easy to understand tutorial gubbeper, thanks for that ! |

http://www.elv-downloads.de/downloads/platinenfolien/leiterplatten.pdf
has some of the words in German ... like "Photopositiv", "Eisen III Chloride", "ätzen" and what not
I did a Google for German pages on the words "platinen selbst machen chloride" (without the quotes), there seem to be lots of useful links. _________________ Jan
also .. could someone please turn down the thermostat a bit.

Thanks for the kind words! I just realized that photo album has 6315 views
I am going to update it soon though. I ran out of spray and started using PCB:s that where pretreated with photoresist and found out that they weren't at all as responsive to the kitchen sink light.
I kind of gave up and bought some special, non kitchen related, equipment It's a very small and generally crappy looking exposure box bought at Kjell.com:
http://www.kjell.com/?item=89445
I'll ad some information about that in the coming weeks.

It should translate as "Photolack/Fotolack". |

I re uploaded the instructions a few messages above that had disappeared somehow. It says "Fotokopierlack" in the lower right corner. Can that be the magic word you're looking for?
