摘要： PROBLEM TO BE SOLVED: To prevent the interface between a sealing resin and a lead frame from being stripped and to prevent a crack from being generated in a sealing resin layer by a method wherein an Sn-plated layer is formed on the surface of a thin plate made of an Fe-Ni-based alloy. SOLUTION: In a lead frame material, an Sn-plated layer is formed on the surface of a thin plate made of an Fe-Ni-based alloy. In addition, by using the lead frame material, a semiconductor device is manufactured by using an epoxy resin composition in which an epoxy resin, a hardening agent and an inorganic filler are contained in a sealing agent. In the Fe-Ni-based alloy, it is proper that Ni content amounts to 30 to 50%. When Ni content amounts to 30% or lower, its thermal expansion becomes large. When Ni exceeds 50%, its strength is lowered. In addition, an Sn-plating operation may be executed to both faces or only to one face. As a planting method, any method such as an electroplating method, a chemical plating method, a vapor deposition method or the like may be used as long as a porous film can be formed. Then, it is proper that the film thickness of an Sn-plated film is 5μm or lower.

摘要： PROBLEM TO BE SOLVED: To attempt manufacturing lead frame member having superior resin adhesivity, soldering wetness and plating characteristics by Ni-Fe alloy lead frame member making heating process in the atmosphere and forming an oxide film with a specified thickness on a surface layer. SOLUTION: A lead frame member with superior resin sealing characteristic shows such superior characteristics as conductivity, mechanical strength or anti-corrosion as an IC lead frame member by being made from a base member as Ni-Fe alloy. An Oxide film formed on a surface layer has an effect which improves adhesivity of the alloy and sealing resin. The thickness of the oxide film must be 10-50nm as a lead frame member not to loose such necessary characteristics as soldering or plating. A method of heating process in the atmosphere can easily control a thickness or a nature of the oxide film and cost is inexpensive for forming the oxide film.

摘要： PROBLEM TO BE SOLVED: To manufacture the clad material whose joining interface of dissimilar metals is flat and whose characteristics are uniform by performing the rolling after removing the ruggedness on the surface generated by the brushing. SOLUTION: A stainless steel/aluminum clad material is manufactured by roll-pressing two metallic strips 1, 2, e.g. stainless steel and aluminum strips. Brushing is performed at least on either of two faces to be joined by a wire brush 4. The skin pass rolling is performed on the brushed metallic strip 1 in the non-lubricated condition using a ceramic roll 5 of smooth surface to remove the ruggedness on the surface generated by the brushing. Then, pressing is performed by the rolling roll 6. The surface roughness Rmax of the ceramic roll 5 is

摘要： PURPOSE: To obtain a lead frame material having excellent solderability and a further improved corrosion resistance by adding Cr, Cu, and Ni in a material composed of Fe and impurities by prescribed weight percentages. CONSTITUTION: A frame material is composed of Fe and impurities and contains 4-10wt.% Cr, 0.1-5.0wt.% Cu, and 0.1-5wt.% Ni. It is preferable to control the mixing ratio of Cu within the range of 0.5-5.0wt.% and that of Ni within the range of 1.0-5.0%. In the conventional Cr lead frame material containing 7wt.% Fe, the surface oxide film of the material can be controlled by adding both Cu and Ni to the material. Therefore, both the solderability and corrosion resistance of the material can be improved further.
