Place fixing holes

Top  Previous  Next

If you want to create a double sided PCB, the first thing you encounter

is that it will be very difficult to flip over the PCB and get it exactly placed

for milling the second side.

This is why we use fixing holes.

Fixing holes are automatically generated by Isocam © so your PCB is

always in the exact position for milling and drilling.
