What is Photo Etching?

Source:本站  Editor:Editor  Click count:1445  Date:2012-9-3 5:58:12  【16 14 12

  Very simply, chemical etching is a process used to remove material (metal) by way of masking an area with a protectant (photo resist) and then submerging the material into an etchant (acid) to remove the material that has not been protected by the photo resist. The resulting pattern can then be posted processed if necessary and then used in the intended application. 

Photo Etching is simply a high-quality, fast-turnaround and low-cost alternative for machining flat metal parts. It offers you the precision and accuracy unavailable in other type of milling processes.


The conventional process meant stamping which required a matched punch and die. It caused stress, deformation and burrs. The photo etching has not only eliminated these problems, but enabled manufacturers to process parts accurately and much faster than before. It doesn´t change the metal composition such as heat or mechanical stress on finished parts.

 Our Photo Etching Process can be performed on practically any types of metal including very thin metal sheets with dimensional tolerances requiring micro precision and offers part manufacturers advantages in several ways. We anticipate still widening areas of its applications in the near future.
