摘要： A semiconductor device having an improved whisker resistance in an exterior plating film is disclosed. The semiconductor device includes a tab with a semiconductor chip fixed thereto, plural inner leads, plural outer leads formed integrally with the inner leads, a plurality of wires for coupling electrode pads of the semiconductor chip and the inner leads with each other, and a sealing body for sealing the semiconductor chip. The outer leads project from the sealing body and an exterior plating film, which is a lead-free plating film, is formed on a surface of each of the outer leads. In the exterior plating film, the number of grains not larger than 1 μm in diameter and present on an interface side in the thickness direction of the exterior plating film is larger than the number of grains not larger than 1 μm and present on a surface side of the exterior plating film, whereby the difference in linear expansion coefficient between the exterior plating film and the outer lead is made small, thus making it possible to suppress the growth of whisker.

摘要： It is suppressed that a whisker occurs on a lead for external connection. A lead for external connection is formed of the alloy (42Alloy) of Fe and Ni, and a plating film which includes alloy of Sn and Cu is formed on the surface. Next, using a heat-treat furnace, the heat treatment at the temperature beyond melting-point T0 of the plating film is performed, and the plating film is melted. At this time, the temperature beyond T0 is held for 20 seconds or more. The grain boundary of the plating film can be vanished by the above-mentioned heat treatment. Hereby, the internal stress of the plating film can be eased, and the generation of the whisker can be suppressed.

摘要： A swash plate type variable displacement compressor has a housing, a drive shaft, a swash plate and a piston. The housing includes a cylinder block, a front housing, and a rear housing. The drive shaft is rotatably supported by the housing. The swash plate is connected to the drive shaft, and is integrally rotatable with the drive shaft and tiltable relative to the drive shaft. The piston engages with the swash plate through a pair of shoes. Rotation of the drive shaft is converted to reciprocation of the piston through the swash plate and the shoes, and the displacement of the compressor is adjusted by varying the inclination angle of the swash plate with respect to the axis of the drive shaft. The swash plate includes a base member made of copper series and a sliding layer coating a sliding surface of the base member with respect to the shoes.
