cjackson Posted February 6, 2006 Report Share Posted February 6, 2006 Anyone know of any companies in the Columbus area that does ciruit board etching from breadboarded circuits? I know OSU Physics department has a chemical etcher, but I don't know if they will etch comercially. I'm working on a Senior project for school and we have about 4 circuits breadboarded and were looking to get them all etched onto one board. If you know, then please forward the info to me. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Trouble Maker Posted February 6, 2006 Report Share Posted February 6, 2006 IIRC you can buy kits to chemically etch your own stuff. The place I used to work did their own proto boards, but they had their own chemical and mechanical etchers. They never used anyone outside. We don't do that type of work where I am now, nor have I ever used anywhere in the past. I'm sure there is somewhere. I think cost might be an issue unless they feel like being charitable since it's for school. I'll ask my dad tonight if he knows anywhere. Just wondering, what's the deal with a 'senior' design and you are 20? Take a few years off in high school. Quote Link to comment Share on other sites More sharing options...
coty061885 Posted February 6, 2006 Report Share Posted February 6, 2006 Just wondering, what's the deal with a 'senior' design and you are 20? Take a few years off in high school. I'm in his Senior project group. We go to DeVry, we have trimesters, therefore we graduate about a year earlier than other bachelor programs at typical colleges. The Senior project is something all students must do in their 8th (of 9) semester. Anyways, on with the topic! Quote Link to comment Share on other sites More sharing options...

GRN96WS6 Posted February 7, 2006 Report Share Posted February 7, 2006 I thought the devry in cbus had a etcher....I seem to recall it being new when I went there. I graduated EET from that campus in 00. Might want to ask the lab guys I'm almost positive they had one. Quote Link to comment Share on other sites More sharing options...
Rally Pat Posted February 7, 2006 Report Share Posted February 7, 2006 if you do go the way of etching it yourself, I feel it is my duty to remind you that chemical etching is very dangerous...very very dangerous... Quote Link to comment Share on other sites More sharing options...
RedRocket1647545505 Posted February 7, 2006 Report Share Posted February 7, 2006 Am I the only one who doesn't know WTF 'etching' a circuit board is? Time to visit my friend, Google. Quote Link to comment Share on other sites More sharing options...
thorne Posted February 7, 2006 Report Share Posted February 7, 2006 Its been a few years since i did PCB's but im 99% sure this is the site we used to use http://www.pcbexpress.com/quickturn-pcb.php?WT.mc_id=psgoo00055 you download software design the board and they can get it to you in like 3 days Quote Link to comment Share on other sites More sharing options...
Cougar1647545494 Posted February 7, 2006 Report Share Posted February 7, 2006 Maybe Andy can still get a hook up from the physics lab on campus Jackson. I'll ask him and report tommorrow at school. Quote Link to comment Share on other sites More sharing options...
v6grandprixgt98 Posted February 7, 2006 Report Share Posted February 7, 2006 if you find etching to be too expensive you may want to look into wire wrap. We use that for a board at work that performs several functions for a gauge to measure thickness of steel. It has about 10 different circuits on it with a few hundred connections. Heres an example I found of what wire wrap looks like: http://www.linuxfocus.org/common/images/article300/top.jpg http://www.linuxfocus.org/common/images/article300/wrap.jpg Its very easy to fix mistakes and modify!

Cougar1647545494 Posted February 7, 2006 Report Share Posted February 7, 2006 We're familiar with wire wrap, we had to wire wrap an entire working clock. What a pain. That may be a good idea though. Quote Link to comment Share on other sites More sharing options...

cjackson Posted February 8, 2006 Author Report Share Posted February 8, 2006 I thought the devry in cbus had a etcher....I seem to recall it being new when I went there. I graduated EET from that campus in 00. Might want to ask the lab guys I'm almost positive they had one. I am one of the lab guys and it doesn't work so good. It's basically like a router that cuts the lines in the board. People have problems with it. Sometimes they have to flash the boards with high voltage to burn out small traces that shouldn't be where they are. Just overall not worth the time to use it. Maybe one night when I'm super bored I'll dig it out and play with it. Quote Link to comment Share on other sites More sharing options...

Fuck wire wrapping in its ass. I wrapped that damn clock twice because a couple wires got crossed in the spaghetti mess of shit. The clock is actually a single board computer complete with ROM, RAM, MICRO, onboard clock, lcd screen, etc. It's called a clock because that's what the code we had did for the OS, it kept track of time. Lots of work for something that's not worth it. Edit: I'll leave the stuff breadboarded before I start wire wrapping, no matter how much better the connections are.
