Paper cutter for cutting PCB

2006-07-02 by alan00463

I realize that a shear is the best way to cut PCB. But
I am looking for a cheap way first. Has anybody tried
cutting either single or double-sided PCB with an office
paper cutting machine?

If nobody has tried it yet, I will try it. If someone
has already tried, let us know.

Some have tried with very good results and some had bad experiences.
I use a lever shear, much cheaper than a normal shear, probably even
cheaper than a paper cutter.

There are two kinds of office paper cutters, one with
a circular blade and the other with a straight blade
that pivots at one end. I have used a straight blade
one on PCB stock without any real troubles. I suspect
that cutting PCB's on the office shear is bit rough on
it, but what the heck. I doubt that the circular blade
paper cutters would work on PCB's at all.

I eventually purchased a 12" (Enco #: 130-5700) shear
from Enco that cuts through PCB's like butter. I got
mine on sale for approximately $70. The current
non sale price is $107.

Hope this helps,

I don't think it has the correct cutting action. I think it'll blunt it very
quickly, even if it does cut it. Tile cutters work very well, I've heard. I
used to get them guillotined where I once worked, in the metalworking shop.

Strangely enough the shearing action doesn not seem to dull the tools very
fast.

I wouldn't expect any visible difference between a PCB cut with a paper
cutter and one cut with a sheetmetal guillotine/shear.

Tile cutters make loads of dust or water spray.

hi,

you can preheat the board and then cut, works fine for me.

I bought a paper cutter from Office Depot for about $30, but it has a
blade that is less then 1/16 inch thick. I tried to cut some 1/16
thick FR4, but I wasn't willing to apply enough force to actually
start the cut. I was afraid it would ruin the cutter.

I just picked up another paper cutter, this time from Harbor Freight.
It was on sale for $13, regular price is about $20. This has a 6mm
thick blade, much sturdier. I had no trouble cutting some 1/16 thick
FR4 with it. It produced a straight, reasonably smooth edge.

The latter paper cutter looks similar to a cutter that I saw used in a
university's prototype PCB shop.

Cheers,
- Jan
