Semiconductor Lead Frames with Metal Etching
Overview:
Semiconductor lead frames with metal etching are precision-engineered components used to support and connect semiconductor chips to external circuits. These frames are typically produced through advanced metal etching processes, which involve the selective removal of material to create highly detailed, intricate designs with tight tolerances. At our facility, we offer a one-stop service, from design and material selection to manufacturing and surface finishing. We maintain strict quality control throughout production to ensure optimal performance and reliability. Additionally, we provide sample production to meet your specific needs and guarantee satisfaction before mass production.

Etching Process
- Cleaning: The substrate is thoroughly cleaned to remove any contaminants and ensure optimal adhesion of the photoresist.
- Photoresist Coating: A uniform layer of photoresist material is applied to the cleaned substrate to create a sensitive surface for patterning.
- Exposure: The coated substrate is exposed to ultraviolet (UV) light through a mask, transferring the desired pattern onto the photoresist.
- Development: The exposed substrate undergoes a development process, where the photoresist is selectively removed, revealing the underlying material in the desired pattern.
- Etching: The exposed areas of the substrate are etched away using a chemical solution, creating the final design.
- Final Cleaning: A final cleaning step is performed to remove any remaining photoresist and etching residues, ensuring a pristine finish.
