Has anyone mounted one of those video pens to aid in drilling PCBs?

If I do not go with a CNC, the press I am considering is this.

I was thinking if I could mount one of those magnifying pens somehow, it would make the job of drilling PCBs a lot easier.

It would probably be best if I can get it inside that housing as close to the chuck as possible. But with that stand it just might work too.

Any ideas?

For me, I would think that 600X is too much magnification for drilling a PCB. Higher mag generally means a smaller focal length. You can see the effect with just a jeweler's loupe at only 7 or 10X magnification. Your 600X microscope wouldn't even provide you a clear view until it was almost touching the PCB. I like your idea of adding magnification, though. I use a scroll saw on wood and need to cut smooth curved lines to make the scroll patterns. I found a lighted magnifying glass at Woodcraft that fit the bill. It's only 10X, but I can split a sharp pencil line in half which I believe is enough accuracy for drilling PCB's, about 0.002".

Thanks for the tip. I would hope those magnfiers are adjustable but your advice will be helpful in confirming that.

There is a thread on Practical Machinist Form about using USB microscopes. Including some software developed by one of the posters.

You will probably have to register to see the photos...but that's free. ;)

Thanks for that information. I saw those before. Thought they looked similar. There are a number of them under different names. This might be swaying me back to proxxon.

you might try a macro or zoom lens for a smart phone and then you have the monitor and camera in a compact position that will fit near your drill. Some lenses are only $15 and likely good enough for drilling.

I have one that I use for close-up surfaces at work - bought it at Five-Below for $5.

I would mount a laser pen under the drill table, inline with the drill bit. That way when the small spot in the PCB 'island' is in the correct position you can tell.
