A question has come up concering the feature size of artwork output from the a cad system. IPC-D-275 indicates 'The appropriate artwork tolerances and allowances shall be incorporated into the production of the phototool'. Does this mean that the cad artwork output should include these tolerances and allowances or that the artwork used by the board shop to fabricate the board shall include them?
