What is C194 material?

C194 is a copper alloy, also known as C19400, that contains small amounts of silver (typically around 0.02% to 0.06%) and other elements to enhance its properties. It is known for its excellent electrical and thermal conductivity, high strength, and corrosion resistance, making it a popular choice for lead frames used in semiconductor packaging. C194 is often chosen for its durability and performance in demanding applications such as automotive electronics and LED packaging.

What materials are used in lead frames?

Lead frames are commonly made from copper-based materials, including pure copper, copper alloys (such as C194, C10100, C7025), and brass. These materials are chosen for their electrical conductivity, thermal conductivity, mechanical strength, and corrosion resistance. Sometimes, stainless steel or aluminum may also be used in specific applications, depending on the requirements for strength and environmental resistance.

What is lead frame plating?

Lead frame plating refers to the process of applying a thin coating of a metal, such as gold, silver, or nickel, onto the surface of a lead frame. This plating serves several purposes, including improving corrosion resistance, enhancing solderability, and protecting the material from oxidation. Plating helps ensure that the lead frame can perform reliably over time, particularly in harsh environments or high-performance applications.

What are the parts of a leadframe?

A typical lead frame consists of several key components:

  • Lead: The electrical contacts that connect the semiconductor device to the external circuitry.
  • Frame: The base structure that holds and supports the leads in the correct alignment during the packaging process.
  • Tie bars: Small connections that hold the leads together and help with the packaging process.
  • Lids and fins: Additional components that are sometimes included to help with heat dissipation or structural stability.
  • Pad and finger: Where the semiconductor die is attached.
