    摘要： A method for assembling a semiconductor package includes a rapid cooling step after post mold curing of an encapsulation material. The rapid cooling step includes blowing chilled, compressed air over the package for about two minutes. The rapid cooling step does not require any clamping pressure be simultaneously applied to the package. The rapid cooling step reduces a temperature of the encapsulation material from a curing temperature to the cooled temperature within a maximum period of less than five minutes. By using rapid cooling, as opposed to cooling the package under a clamping pressure with ambient air, package warpage due to CTE mismatches is prevented.

    摘要： In a method of packaging a semiconductor IC, a tape is attached to a back surface of a lead frame array, and the lead frame array is held between an upper mold chase and a lower mold chase of a mold, with the back surface of the lead frame array upward. The upper and lower mold chases form an upper cavity and a lower cavity with respect to the lead frame array respectively. A mold compound is injected into the upper and lower cavities respectively. With respect to clearances between leads, between die pads and/or between the leads and the die pads, the mold compound injected into the upper cavity covers the portion of the tape over the clearances before the mold compound injected into the lower cavity fills the clearances, so that the tape is depressed. After curing the mold compound, removing the mold and de-taping, the mold compound filled in the clearances is recessed inward from the back surface, which increases the solderability in the subsequent surface mount process and decreases the possibility of the occurrence of lead short-circuits.

    摘要： When visualizing the stress distribution of natural bone, synthetic bone, or a member attached to either thereof without omitted points, in order to measure accurately in a variety of modes using an inexpensive system, a mechanoluminescence material thin film 6 is formed in advance on a bone material peripheral surface 5 in an appropriate area thereof including the portion where an insertion support portion 4 of an artificial hip prosthesis 2 is inserted into a hollow inside 3 of a damaged femur 1 or a synthetic bone simulating the damaged femur. The mechanoluminescence material thin film 6 portion is photographed over its entire circumference with an IICCD camera 7 from the external peripheral side thereof as or after the artificial hip prosthesis 2 is inserted. The obtained image is fed to a computer 11 to obtain a luminescence image 8. The computer 11 outputs the intensities of the received light in the form of an image as is, so that the luminescence image 8 can be obtained easily. Particularly, the data about the intensities of the received light can be used as stress/strain data virtually as is. Such method is also suitable for dynamic analysis.

    摘要： A stress-induced light emitting composite material according to the present invention contains at least stress-induced light emitting inorganic particles, which emit light at application of a mechanical effect thereon and a polymer material. The stress-induced light emitting inorganic particles are not more than a wavelength of visible light in particle diameter and surface-treated. With this arrangement, the stress-induced light emitting composite material becomes transparent in a visible light range. Moreover the surface treatment of the stress-induced light emitting inorganic particles give water resistance to the stress-induced light emitting inorganic particles.
