Got the same problem.

The Linear Tools 59-650-747 is ideal (about 25$) :

Multi-coated Acrylic Lenses offer a choice of 4 magnification powers via
combination of fixed , flip-up and monocle lenses: 1.5, 3.0, 9.0 and 10.5
Adjustable light incorporated.

a écrit :
I need to purchase a magnifier so that I'll be able to do things like replace eproms and other small SMT's.

I'm not looking to do LSI's with 150 pins Etc. Just mostly smaller
stuff. For instance I currently have a board that needs an 8 pin Eprom
replaced.

I thought that I could do it with the magnifiers I have but the stuff
is Just too small. I tried using a high res TV camera with a varifocal
3.5 to 8 mm lens but it doesn't make the image large enough.

I was wondering what people are using to do this. Thanks, Lenny
