    摘要： There is provided a lead-free solder which makes it possible to reliably and accurately perform the inspection of various kinds of defective soldering in the inspection using an image inspection apparatus after the reflow soldering. According to this lead-free solder, the delustering of the metallic luster of fillet is realized in order to minimize the probability of generating a dark portion at the area where no defective soldering is existed and instead to increase the area of whitish portion which can be generated through the irregular reflection of beam. Specifically, this invention provides a lead-free solder comprising an Sn—Ag—Cu-based lead-free solder containing a small quantity of Bi and Sb as an element which is capable of generating a delustering component for minimizing metallic luster of the fillet.

    摘要： A thermal expansion coefficient of a module substrate 8 is different from that of a package substrate. There is not any place where stresses generated in Interfaces between soldering balls 5 and the substrate are released. These stresses are largely applied to soldering bond, the soldering balls are strained, deformed, or cracked, and there has been a problem in long-time reliability. Slits are disposed on opposite sides of each soldering ball in a vertical direction to a side in an outer peripheral side of the package substrate, accordingly the stresses applied to the soldering balls are weakened, and the soldering balls are prevented from being strained, deformed, or cracked. When soldering strains are reduced in this manner, there can be provided a surface mounting type semiconductor package and system module having high reliability, low cost, and satisfactory electric characteristics such as low capacitance and low inductance.

    摘要： An antenna for a portable radio apparatus has a first antenna construction connected to the casing of the apparatus and a second antenna construction affixed to a base plate or earth plate which is incorporated in the casing. The first antenna construction has a movable joint which allows the first antenna construction to move between a first position where it is regarded as forming a part of the contour of the casing and a second position where it is protruded from the contour and regarded as being located in free space. The second antenna construction corrects the matching state of the first antenna construction such that adequate antenna radiation characteristics are set up in the first position. Optimal antenna characteristics are, therefore, achievable when the first antenna construction is in any one of the first and second positions.
