Title: Useful idea when drilling PCBs
Post by: a soBer Newt on January 03, 2012, 01:14:29 PM
Not my idea but well worth sharing I thought

Seems cool.. but not worth it.. for home use i´d say your eyes will do it just fine... :D

i use a lamp with a magnifying lense to solder these days... ::)

I wear glasses as well, i find it easy to drill just by looking wuth my eyes when drilling IF its a smal PCB and not 1000 holes to drill :D

"I use a lamp with a magnifying lens to solder these days..."

I'm not quite there yet, but estimate I'll be joining you in about another two years or so. I used to just be short-sighted, but now I'm becoming long-sighted as well as short-sighted. Eventually I guess I'll only be able to see things that are exactly six feet away!

Well , i am joining too . Not that i am short sighted or long-sighted , my magnifier doesn't work properly !  :icon_mrgreen:

Let me guess... you're about 40 or 42? (That's when it happened to me).

Assuming you don't want to undergo painful arm-lengthening surgery.  Get some of these: http://www.doneganoptical.com/optivisor.php (http://www.doneganoptical.com/optivisor.php)
They are pricier that some, but great quality, and you can swap lenses with different magnification.

For the OP - very cool (if a little excessive).

Oh yes , if you want 'them microscopes :

But the 2nd one is awesome ! See the attached SMD shots  :icon_mrgreen:
Here's hoping they work , but it should , if it doesn't get a refund .

Me too, used to have amazing eyesight, but last year the windows product key started getting hard to read when installing windows, now i can't even read the newspaper. A couple of years ago i could remove and resolder 48 pin TSOP chips by hand with no sight aids. Yes at early 40's presbyopia sets in and you can't fix it with anything except stronger and stronger glasses. :(

What a challenge to build something like this, time to time I'm considering it, that would be a great tool!

Reading all this, I noticed how uncomfortable my eyes felt after staring at this PC screen for the last couple hours...

I'm 21 and I feel older than I should.  I don't think I'll have many remaining useful body parts by the time I'm 40.

I did. (out of scaffolding pipe, old dot matrix printers and computer cabinet blanking panels ....fugly as could be.

It was a great challenge...the results were great, but my oh my what a time sump....it's a whole new genre - building it is just half the story...you've then got to calibrate it, learn how to use the code that drives it etc (even just aligning your etched pcb so that the drilled holes all end up in the right place is a ballsache).....like I say a great bit of brain food.....but don't enter into it lightly.

Knowing what I know now, I'd say buy a secondhand one off ebay and use that to learn.....even better, just learn how to move over to SMD! That said, even that poses similar problems....dispensing the paste accurately and in a timely manner for prototypes, for which I will press my CNC into action to yield something like this http://www.youtube.com/watch?v=mG_Sy0FT3EA ...I'm about 80% there for that method)

Thank you.  I've been pondering a solution to that, and this will do very well.  Even an analog solution that uses a lens and a mirror would be super sweet.

Yep, I did feel that this would be huge..

I actually just sold it last month ( don't have access to my photos of it presently - but believe me ...pretty it was not). The reason I sold it was to get even more accuracy....I bought a brand new one from those friendly folks in Asia. My DIY build was fine enough for drilling out say thru hole....but not really sufficiently accurate to dispense say a tiny bit of solder paste on a SOT23-6 pad.

I don't think most hobbyists realise just how much of a win a CNC machine is....it's not just drilling out pcbs, but a whole gammut of stuff that until you get one, you then wonder why every man doesn't have one in his garage!  (ok cost might be one reason....but you get the drift)....so if you can beg steal or borrow one (or buy a sh one on Ebay).....make the effort, you'll never look back - everything becomes possible (or at least it adjusts your mindset so that everything seems possible - and with that is 80% of the battle won IMHO)

Gurner, Do you have any links to the CNC machine you got, I would love to get a small cnc miller. 1. For drilling pcb's and maybe for accurate drilling of enclosures. 2. I do some radio controlled modelling so it would be a great thing to be able to mill small parts for modelling as well as some small milling off motorcycle stuff.

The thing is with CNC machines...it's really down to its intended use - for me ...acrylic & pcbs - neither of which stress the machine that much. But when you start mentioning motorocycle parts, I start envisioning milling steel parts etc - that needs a very expensive machine (on account it need to be *very* strong & rigid).

This was the machine I bought....

http://www.ebay.co.uk/itm/Panther-210-CNC-Router-PCB-Engraver-mill-Machine-/230715495294?pt=LH_DefaultDomain_0&hash=item35b7b7137e (I think it might be referred to as a sable CNC machine in the States....typing that into youtube will get you plenty videos of the same machine)

actually, having only used it for a couple of weeks...it'll be going up for sale. Nothing wrong with the build per se, but they stretched the boundaries a little with respect to feed rates (how fast the tool can move about), it's a little too slow for my needs, so it'll be going up for sale. I reckon it'd be capable of light aluminium work, if you kept the cut depth small....but then this would take a good while to complete a part!

Most make the mistake of thinking they can buy a machine that'll do everything well - this is not the case. A CNC machine for pcb needs a completely different spec to a machine for say milling aluminium...so be sure to nail down your main requirements well & hunt for a machine that suits. I found this site reasonably helpful .... http://cncdiy.org/ (click on 'how do I select a cnc machine for myself')

Thanks for the info on that, I did think as I typed out that motorcycle parts would be way over the cost of the type of cnc machine I would be aiming at. Something that can cut aluminium hammond type of enclosures would be about the most strenuious thing it would need to mill.

I will have a read up on the cncdiy.org you linked for me, thanks

Here is a CNC machine/kit diy unit that I came across some years back but now updated. The man who goes by the name Clanzer who does this used to make quite a lot of kit I used to use in the past. He is back with this new machine that is meant for lots of milling jobs, including accurate PCB milling, drilling and solder paste.

@Gurner, it might be a good read if your looking to get another cnc machine, also the Clanzer dude is easy to talk to and very helpful.

Proxxon is cast into the side of the press, you can see it in the opening seconds of the clip.  My guess is that it's this one: http://www.proxxontools.com/store/pc/viewPrd.asp?idcategory=33&idproduct=32 (http://www.proxxontools.com/store/pc/viewPrd.asp?idcategory=33&idproduct=32)
