Title: Variable angle ultrasonic flaw detecting method
Inventor: MORIMOTO KAZUO
IPC: G01N29/04
Filed: 1985-12-26
Abstract: PURPOSE:To detect a defect easily and securely by a K-scan ultrasonic flaw detecting method by making the intervals between a transmitted and a received ultrasonic wave sensor constant, and varying an angle of refraction and performing the flaw detection. CONSTITUTION:The distance L between the ultrasonic wave sensor 5 for transmission and the ultrasonic wave sensor 6 for reception is fixed and flaw detection is performed at the weld zone 2 of a sample 1. If there is a defect A in the weld zone 2, an ultrasonic wave which is incident from the sensor 5 at an angle theta1 of refraction is reflected as shown by a solid-line path and received by the sensor 6. If there is a defect B, the ultrasonic wave from the sensor 5 changes in direction and is incident at an angle theta2 of refraction and reflected as shown by a dotted-line path, so that the light is received by the sensor 6 at the same position. Thus, the angle theta of refraction is varied with the depth D from the bottom surface to the defect to performs the flaw detection, thus detecting defects of various depth. Thus, the angle of refraction of the ultrasonic wave sensors for transmission and reception is varied, so a defect is detected securely even if the defect has different depth.

Abstract: PURPOSE:To dissipate heat generated from a chip into an atmosphere from the bonded part of the chip to a cap and to maintain a good element characteristic even when the chip is integrated highly by a method wherein the mounting face of the chip and the attachment face of a lead pin are formed as a so-called facedown or cavity-down constitution in which they are set on the same face. CONSTITUTION:A plurality of lead pins 17 are installed in a grid shape at the peripheral part excluding a second opening part 13 in a circuit board 14. A semiconductor chip 22 is mounted, via a pedestal 21, on the back of a cap 20 corresponding to the upper part of the second opening part 13 in the circuit board 14. Heat which is generated from the chip 22 is conducted mainly from the bonded part of the chip 22 to the cap 20, and it is dissipated into an atmosphere from the cap 20. At this time, a thermal resistance thetaj-c between the chip 22 and the cap 20 is equal to that in conventional types, but a thermal resistance thetac-a between the cap 20 and the atmosphere becomes smaller than that in conventional cases. This is because a heat-dissipating property from the surface of the cap 20 is higher than that from the back side of a stem 11.
