Photo Etch Basics

Sheet sizes

  • Standard size 12 x 24"
  • Maximum size with in-house tooling 18 x 24"
  • Maximum size 36 x 59" (tooling cost higher)

Smaller sheet sizes also possible

Tolerances

  • Standard is +/- 10% of material thickness. Call if you have additional needs
  • Smallest diameter hole needs to be greater than material thickness
  • Space between holes must be greater than metal thickness
  • Inner radius must be at least 100% of material thickness, outer radius must be at least 75%
  • Edge condition is burr free, however, there is a bevel on the edge equal to about 20% of material thickness

Optimal Material Thickness

  • Optimal: 0.002" to 0.030"
  • 0.030" to 0.062" possible, but higher cost
  • <0.002" possible
PARTIAL ETCHING

Half-etches or partial-etches (etching partway through the metal) can be used to create bend lines for manual forming, part marking, or other features. Guidelines for include:

  • At least 0.002” metal remaining at the bottom of the partial etch preferred
  • The width of the partial etch should be at least 1.5x the depth

Photo Etching Can Be Performed

On A Variety Of Materials

Are you looking for a way to produce custom parts or prototypes quickly and within budget? Photo etching may be your answer. Tooling is less expensive and faster than other processes, making photochemical etching useful for prototyping as well as cost-effective mass production.
