SinoGuide strive to be a leading manufacturer in the precision photochemical etching industry. Photo etching produces intricate
components with exacting tolerances that are impossible to duplicate by other processes.
All dimensions, tolerances and configurations are functions of the thickness of the material being photo etched and should be
considered during the design process. The following guide gives practical limitations for chamfer, holes, spacing and construction
dimensions with relation to metal thickness for photo chemical milling.
See Figures 1 at the right for a representation of the features referenced. Consult us for design assistance when these situations
occur.
