Production Process:

1. Material Preparation: The process begins with the selection of high-quality copper sheets. These sheets are carefully cleaned and prepped to ensure optimal adhesion during etching and stamping.
2. Photoresist Application: A photoresist layer is applied to the surface of the copper sheet. This protective layer is used to define the areas of the copper that will be etched. The material is then exposed to ultraviolet (UV) light through a photographic mask that outlines the desired pattern.
3. Etching: After exposure, the photoresist is developed, and the exposed areas of the copper are etched away using a chemical etching solution. This removes unwanted copper, leaving behind the lead frame pattern.
4. Stamping: Following etching, the copper sheet is placed in a stamping press where it is formed into the final shape of the LED lead frame. This process uses precision dies to punch, bend, or form the copper into the required configuration.
5. Plating: Once the copper lead frame is stamped, it may undergo a plating process such as gold, silver, or tin plating to improve electrical conductivity, corrosion resistance, and surface finish.
6. Inspection and Quality Control: Each lead frame is carefully inspected to ensure it meets dimensional tolerances and quality standards. Key checks include visual inspections, dimensional measurements, and functionality tests.
7. Cleaning and Final Processing: The final lead frames are cleaned using ultrasonic or other advanced cleaning methods to remove any residual chemicals or contaminants. Additional finishing processes like polishing may be done for a smooth, refined appearance.
8. Packaging: The completed LED lead frames are then packaged according to customer specifications, ready for shipment.
