Title: Controller for channel selection circuit
Inventor: OKAMURA KATSUTOMO
IPC: H04N5/44
Filed: 1985-07-15
Abstract: PURPOSE:To allow the user to set freely a channel up/down channel selection speed as preference by using a preset signal from a means generating a prescribed preset signal so as to switch a channel switching speed setting data generated by the depression of a channel up or down key into another data. CONSTITUTION:A voltage produced across a resistor R2 through the current flowing from a voltage source 21 to resistors R4, R2 by closing, e.g., a contact S2 is generated at a terminal P2 via the 3rd port 19. Then a CPU 17 detects a signal caused at any of preset terminals P1-P3 and decides to which contact the signal corresponds to give a data different from contacts S1-S3 to a register 26. Thus, the difference between the initial value of a counter 25 and a reference value of the register 26 is varied so as to change the switching speed of the channel depending on the position of the contacts S1-S3.

Title: Solder ball inspection method
Inventor: YANAGIDA TOSHIHARU
IPC: G01L5/00
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To detect failure of a solder ball before mounting a chip that cannot be detected in electrical inspection. SOLUTION: A physical measuring probe 7 is made to scan horizontally while keeping constant probe height (h) on a device chip with a solder ball 6 fixed thereto, and in the case rupture limit probe load at the rupture of the solder ball 6 is larger than the specified value, the solder ball 6 is judged to be nondefective, and in the case of being smaller than the specified value, the solder ball 6 is judged to be defective. The good solder ball 6 leaves a solder residual film 6r in such a way as to almost cover a BLM film 5 because of being ductility ruptured, put the defective solder ball 6 has a small quantity of solder residual film 6r because of being brittlely ruptured, and the exposed area of the BLM film is large, so that optical microscope observation can be combined in quality judgment.  In addition, an acceleration degradation test of a solder ball junction can be performed by heating the device chip to high temperature before scanning by the physical measuring probe 7. Quality can therefore be judged on a stricter basis than before.
