Photo etching capabilities include a range of metal thickness generally between .002″ to .060″. Tolerances can be maintained to the relative thickness of the metal. Minimum holes and slots must be at least 110% of the metal thickness.  Minimum dimensional tolerances are +/- .15% of the thickness and a  minimum of +/-.0015" on metals .010" and less. Please see our technical data sheet for details of our capabilities.
