Photo Chemical Machining Process
The Photo Chemical Machining process has 9 essential steps to achieve simple or complex thin-metal components of one to one million parts. This is a very economical option for research and development or prototype phase of a project when quick turnaround is vital. Our PCM process is used to etch through metal thicknesses between .0005″ to .060″ and between .060″ to .250″ for depth etching on metal only.

At Dragon Etching, we take pride in our cutting-edge laboratory facilities. These facilities are equipped with the latest technology and machinery that allow us to achieve the highest standards of precision and efficiency in Photochemical Etching. Our team of skilled professionals operates in an environment that fosters innovation and excellence, ensuring that every project meets the most stringent quality standards.

Comprehensive Photochemical Etching Process

It’s widely recognized that to complete the entire etching process, a variety of equipment is required in addition to the photochemical etching machine. At Dragon Etching, we offer two different combinations of photochemical services, each tailored to specific needs:

Option 1: Using Dry Film  what is dry film etching?

  1. Cleaning Link: The cleaning process is crucial to remove any contaminants, ensuring a clean surface for subsequent steps. It prepares the material for the photoresist application.
  2. Lamination Link: In the lamination step, a dry film photoresist is applied to the cleaned substrate. This photoresist acts as a protective layer during the etching process, defining the areas that will remain after etching.
  3. Exposure Link: During exposure, the substrate with the dry film photoresist undergoes a precise exposure to UV light. This step transfers the desired pattern onto the photoresist.
  4. Developing Link: In the developing process, the exposed photoresist is developed, leaving behind the patterned areas. Unexposed areas are removed, revealing the underlying material.
  5. Etching Link: Etching is where the actual material removal occurs. The substrate is exposed to etching chemicals, which selectively remove material according to the pattern defined by the photoresist.
  6. Stripping Link: After etching, the remaining dry film photoresist is removed, leaving you with the final etched product.

Option 2: Using Wet Film what is wet film etching?

  1. Cleaning Link: Similar to the dry film process, the cleaning step is essential to prepare the substrate by removing contaminants.
  2. Lamination Link: In this step, a wet film photoresist is applied to the substrate, forming a protective layer for subsequent processes.
  3. Exposure Link: The substrate with the wet film photoresist is exposed to UV light, creating the desired pattern on the photoresist.
  4. Developing Link: After exposure, the photoresist is developed, revealing the patterned areas on the substrate.
  5. Etching Link: Etching, as before, is where the material is selectively removed according to the pattern defined by the photoresist.
  6. Stripping Link: Finally, the remaining wet film photoresist is stripped away, leaving behind the finished etched product.

At Dragon Etching, we offer both dry and wet film processes to cater to a wide range of project requirements. Our state-of-the-art facilities and experienced team ensure that each step of the process is executed with precision and efficiency, resulting in high-quality products for our clients.
