Curved PCB design

[Martin Griffith]

Just looking at a box
http://hammondmfg.com/1553.htm

and the datasheet
http://hammondmfg.com/pdf/1553B_BAT.pdf

Bottom right drawing of the PCB, says a radius of357.35mm for the
curve.

Where do I make the centerpoint of the arc in my ancient Accel PCB
draughting package

Looks like it might be through the two big slots 2/3 way up

Yep, seems to be, thanks

Ok, this isn't to hard but hopefully you can follow:

1. Draw circle with radius 357.35mm
2. Draw circle with radius 357.35mm with center 645.5mm away from previous
center.

These give you your two concentric circles that form the sides. The line
connecting the two centers will be called CL

3. Draw a line 25.9mm above and parallel to CL that connects the two
circles. This gives the top.
4. Draw a line 52.28mm below and parallel to CL that connects the two
circles. This gives the bottom.

That should give your outline. Note that these use the absolute max so you
might want to scale them down a little(a mm or two)


BTW, what does something like that cost?
