Photo etching, also referred to as chemical etching or photochemical etching, is a manufacturing process employed to create precision components featuring intricate designs, fine details, and strict tolerances. It leverages a blend of corrosion-resistant masking, precise photographic techniques, and chemical reactions to carve and mold metals. This advanced technology excels in achieving precise processing for ultra-small, ultra-thin, and intricate shapes, rendering it indispensable not solely in the electronics sector but also in diverse fields like optics, electrical engineering, and electronics. Particularly ideal for manufacturing applications requiring precision and customization, this process stands out for its capability to meet exacting standards.

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.
