Drilled hole position tolerance
Hello
I would like to know what is the tolerance for drilled holes on a 2 sides PCB manufactured with PCBpool. I have a square PCB with 4 mounting holes (D3mm) on the corners, and I wish to use them to center an optical chip on the board. They are distant of 71mm. Could you give me the manufacturing tolerance of the drill position (ie 71mm +/- xx um)
Thanks

Hello Vincent Moreau,

according to specifications for our drilling machines position accuracy and consistent accuracy are +/- 0,002mm.
