Making pcbs

terrydark

Hi everyone,

 

This is my first discussion but I would like to see what the consensus is using  the knowledge and experience of all that have manufactured their own boards using "home brew" techniques.

 

In in your opinion, what is the best or perhaps economical and least fiddly of the methods for producing pcb boards via DIY?

 

Thanks in advance

 

Terry

    As far as I know there is no convenient or free legal way of disposing of the waste products from etching copper from boards. In my youth (alas distant, early 1970s) I poured it down the drain but I understand…

    I have a set-up in my garage. Agitated ferric-chloride bath, tin plating, wet saw, ventilated drill press, xytable. I have a thermal press that directly transfers stencils from a laser-printer. Haven't…

    Thanks for the advice everyone.

     

    As far as getting rid of the Cu, I can get rid of it when I need to through a local metals dealer who does some plating and my small amount of chemicals won't make a dent in theirs. So that doesn't worry me.

     

    I attempted etching 35 years ago but did a poor job of it and resorted to paying for having prototype boards made for me. An expensive path to take in my town.

     

    Does anyone do toner for smd boards?  Is there a high reliability way of doing this?

     

    I have seen milled boards around the "local" hackerspace and they looked good but I can't get there anymore though due to an illness. How much money has to be forked out for a mill suitable for smd?

     

    Haven't done anything previously with photo resist but have watched a few youtube videos. I seem to remember a video or tutorial on using a film based resist system but of course, I cannot find it anymore. If anyone knows of it and has a url can they pass it along? I think the guy used a laminator.  I watched so many videos last year on toner methods and etching I lost track.

     

    Any advice on other systems?

     

    Thanks again to all who responded

     

    I don't know why I spelled pcbs with a apostrophe ... my wife and I had a discussion on this just the other day about how bad spelling and grammar is getting and I just did it myself!!  I should have spelled it as pcbs .. just found a way to correct.

     

     

    Regards
