Lead Frames

Lead frames are critical components used in semiconductor devices to provide electrical connections between the silicon chip and external circuit boards. Widely utilised across the UK’s electronics and manufacturing industries, these metal frames serve as a structural backbone in IC packaging, ensuring signal integrity and heat dissipation. Ideal for high-volume production, lead frames are designed to enhance reliability, reduce cost, and improve assembly efficiency. Additionally, lead frames are inserted into semiconductor packages where a silicon chip is attached. Bonding wires connect the chip’s internal circuits to the frame’s leads, which extend outward to connect with external components. The frame also supports heat dissipation and structural integrity throughout the chip’s lifecycle.
