Production Process:
- Material Selection and Preparation: High-quality copper or copper alloy is selected for its excellent electrical conductivity and is pre-processed to the desired thickness and dimensions.
- Metal Stamping: The copper material is subjected to precision stamping using multi-step progressive dies to form the lead frame’s intricate patterns and components. This step ensures that the dimensions, shape, and design specifications are met.
- Etching: After stamping, the lead frame is often etched to create precise outlines and improve the surface for plating. This step ensures high-quality bonding and functionality for semiconductor packaging.
- Golden Plating: A thin layer of gold is electroplated onto the stamped lead frame. Gold plating provides excellent conductivity, corrosion resistance, and ensures the reliability of the lead frame in high-performance semiconductor applications.
- Inspection and Quality Control: The finished lead frame undergoes rigorous inspection processes, including visual checks and dimensional verification, ensuring that the lead frame meets the required specifications with tight tolerances.
- Final Packaging: The lead frames are carefully packed, ensuring they are protected from damage during transportation and handling before they are delivered to clients.
Post Process:
- Passivation: A chemical treatment that improves corrosion resistance by forming a protective oxide layer on metals, enhancing durability, especially in harsh environments.
- Silver Plating: A thin silver coating applied to improve electrical conductivity, corrosion resistance, and solderability, commonly used in electronics.
- Nickel Plating: Electroplated nickel provides increased hardness, wear resistance, and protection against corrosion, ideal for industrial and automotive parts.
- Tin Plating: A tin coating that enhances corrosion resistance and improves solderability, widely used in electronics to prevent oxidation.
