Photo Etching – Chemical Etching
Chemical milling corrosively machines away selected sheet metal material to produce a complex part with fine detail. Photo etching can be used as an alternative to stamping, punching, water jet cutting or EDM for very thin gauge parts.
Typical material thickness-under 0.05” (1.3mm).
This process is also called Photo chemical machining – PCM, Chemical etching, Chemical milling.

Guidelines for the design of etched components
|≤ 0.002 in||+/- 0.0002 – 0.0004 in|
|0.002 – 0.005 in||+/- 0.0004 – 0.00078 in|
|0.005 – 0.008 in||+/- 0.0012 – 0.0016 in|
|≥ 0.01 in||+/- 0.002 in|
Minimum Hole Size
|Thickness||Minimum Hole Diameter|
|0.002 – 0.004 in||1.2x material thickness (in)|
|0.006 – 0.0078 in||1.1x material thickness (in)|
|≥ 0.01 mm||1.0x material thickness (in)|
|Thickness||Minimum Line Width|
|0.004 in||0.0025 in|
|0.006 – 0.0078 in||0.004 in|
|≥ 0.01 in||≥0.006 in|
Etch profile is maintained at approximately 10-20% of the material thickness.
