Selective Etching
Fotofab can selectively etch your part so that any portion of it can end up approximately half the thickness of the original metal sheet. This technique gives you the option to have us chemically engrave the identification number or a company logo, for example, into your part.
Another selective etching option allows you to integrate bend (score) lines into your design. Applications that benefit from bend lines for easy manual folding include such diverse parts as complex screen enclosures and RF shields for surface mount boards.
You can also design larger portions of your part to be etched to approximately half the thickness of the metal. We refer to these selectively etched areas as step etched areas. You can take advantage of this option, for example, to provide a recessed area in a metal part to place and protect a self-adhesive label.
