Photo etching, also known as chemical etching or photochemical etching, is a manufacturing process used to produce precision components with intricate designs, fine details, and tight tolerances. It utilizes a combination of corrosion-resistant masking, precise photographic techniques, and chemical reactions to cut and shape metals. This specialized technology is capable of achieving precision processing for ultra-small, ultra-thin, and intricate shapes, making it indispensable not only in the electronics industry but also in various other fields such as optics, electrical engineering, and electronics. This process is particularly well-suited for manufacturing applications where precision and customization are essential.

Advanteges of Photo Etching

  • Precision Processing
    It excels in ultra-fine, high-density, intricate, and ultra-small component manufacturing.
  • Sheet Thickness Processing
    It allows for processing materials at their actual sheet thickness, facilitating arbitrary groove shapes or the creation of protruding shapes within the material thickness.
  • Material Integrity
    Photo etching does not alter the material's properties, ensuring no burrs, bends, or deformation occur during processing.
  • Cost-Effective with Low Initial Investment
    Unlike traditional methods, photo etching does not require expensive molds or jig tools, resulting in significant cost savings for initial investments.
  • Quick Turnaround:
    Photo etching is highly responsive, making it suitable for time-sensitive deliveries and small lot production runs. The shortest delivery and lot times can be as quick as one day for a single piece.
  • Complex Geometries
    It is ideal for producing components with complex geometries, intricate designs, and tight tolerances.
  • Customization
    Photo etching allows for customization, facilitating rapid design changes and prototyping.
  • Material Versatility
    It offers flexibility in material selection.
