Major congrats on your first! Which method did you use?? What with?
I've done oddball stuff but no PCB layouts (that are transferrable. Everything I do is "poor man's surface mount". No hole drilling! Woo hoo! lol ) |

i used the press n peel kit from small bear. worked out great BUT drilling sucks. what is poor mans surface mount? do you mount on the same side as the copper like bernie hutchins recommends?
i have a cheap hand drill and i have already BROKEN 5 bits!!! (#60 and #65) these are the bits i bought from small bear and they are steel not carbide and they dont work too well with a hand drill. after ten holes they start getting weak and SNAP.
so now i have about 5 holes left and my drill needs to be recharged. anyone know if a dremel works better? _________________ -------------------------------------------- check out various dan music at: http://www.myspace.com/lossnyc

I broke a million of those bits when I first started making PCB's. I eventually got a small drill press (on sale for $40ish at Harbor Frieght when I got it. They seem to go on sale every other weekend), and that seems to do the trick. The trick to not breaking them is coming in and pulling out perfectly straight. _________________ When they plug me in the lights go down in Hong Kong.

I used to do it with a big hand held drill, and eventually got quite good at it - drinking 'exactly' one beer helped
The drill has to run continuously, and you hold it up with two hands supporting it from below, then let it come down on it's weight and push it up again. That way the bit won't bend for some reason. It actually worked better than a dremel thingy. _________________ Jan
also .. could someone please turn down the thermostat a bit.

If it's ferric chloride, then the answer is yes. I reuse mine a lot, which brings up the question of how to know when it's done. If it's not ferric cholride then sorry, I don't know about reuseability.

I used to do exactly that before I got the drill press. Beer works but coffee's a bad idea. _________________ When they plug me in the lights go down in Hong Kong.

I usually replace it when etching starts taking noticably longer. It also changes colour as it gets saturated with copper.

I couldn't work without a drill press anymore... _________________ http://www.casia.org/modular/ |

how do people dispose of their ferric chloride? I need to solidify my etchant as I work in a over 100 year old building and the pipes would probably dissolve. I tried putting plaster in it once, because I had a kit once with plaster like neutraliser in it - amazing reaction but not the same as the neutraliser just went foamy and sandy! I read that sodium carbonate ( baking powder ) neutralises it. I hate ferric chloride, going to move to the transparent stuff when I use mine up.
this isnt a chaos circuit, but it creates interesting patterns

i have to whole-heartedly recommend the hydrogen peroxide/muriatic acid solution over FeCl- it is less expensive (and fast! and clear!) than both that and the other stuff(ammonium persulfate?) it is a bit more caustic though. gloves, handling utensils and ventilation required! also, always acid into water when mixing (slowly!). never the other way around. i just remember it alphebetically.

re drilling: There's a drill press accessory that goes with the Dremel tools that's fairly cheap. Makes for great PCB drilling. Takes up a lot less space than a real drill press, & if you already have a Dremel, it's definitely cheaper. |

On the back of my ferric chloride it says "Discard used solution into toilet bowl and flush". This doesn't seem like the best idea too me, but who am I to argue with the bottle? I do know the water treatment plants use it (to remove phosphorus i think) in their treatment process.
My used ferric chloride is actually sitting in a milk bottle in my garage. Right next to my used motor oil I haven't disposed of. _________________ When they plug me in the lights go down in Hong Kong.
