Leadframe meaning
Web30 mrt. 2024 · When manufacturers have strict tolerances, testing requirements, and function standards they must adhere to, it makes more sense to use hard tooling over soft tooling. This tooling type is ideal for producing durable high-precision parts. However, hard tooling is considerably more expensive and time-consuming than soft tooling, both in … WebThe silicon chip in integrated circuits is bonded to a metallic substrate, called a lead frame, which provides for mechanical support and heat dissipation. Alloys based on Fe–42% Ni have a CTE close to that of silicon, thereby minimizing thermal stresses, but at a cost in thermal conductivity.
