Title: Measurement of semiconductor package and applicable tray to the same
Inventor: IKEDA SHIGEO
IPC: H01L21/66
Filed: 1990-02-28
Abstract: PURPOSE:To enable the semiconductor package to be measured without fail even if it is provided with multiple ultrafine pins by a method wherein the measurement electrodes are brought into contact with the mutually adjacent leads of a semiconductor package in the inverse direction from surface to rear surface and vice versa. CONSTITUTION:Multiple leads 11-11 are provided from the side of an IC package 10 at specific interval while the leads 11-11 are bent downward from the intermediate part and then further bent taking almost L shape to be fitted for the surface mounting of a printed substrate. Then, measurement electrodes 12A, 12B are alternately brought into contact with the leads 11-11 successively in the inverse direction from surface to rear surface and vice versa. Resultantly, the pitch of the measurement electrodes 12A-12A positioned on the surface side of the leads 11 as well as the measurement electrodes 12B-12B positioned on the rear surface side of the leads 11 can be made twice as much of the pitch of the leads 11-11. Through these procedures, reliable measurement is carried out even if the pitch of the leads 11 is made fine.

Filed: 1991-03-13
Abstract: PURPOSE:To completely prevent a dark current from being produced. CONSTITUTION:A P-type diffusion layer 8 for prevention of dark current production is formed so as to cover the entire region of an N-type diffusion layer 3 in a photodiode formation region, and so as to be connected with an N-type diffusion layer 6 in a charge transfer path formation region under a read gate 30B.

Abstract: PROBLEM TO BE SOLVED: To diagnose the operation of a photocoupler circuit for feeding the operating state of an output driving circuit for driving a load back to a control part based on a control output signal from the control part. SOLUTION: When a transistor Q11 for load driving of an output driving circuit 10a is turned off, a current flows to a photodiode PD 21 through the route of a load 9a, resistor R21 and photodiode PD 21, a phototransistor PT 21 is turned on, and signals at an L level are fed back to control parts 2 and 3. Based on a forced cut-off signal 7a, a primary side current cut-off part 8 cuts off power supply to the load 9a. The control parts 2 and 3 confirms the normal operation of a photocoupler circuit 11a based on the change of the output of the photocoupler circuit 11a into H level as a result after the current supply to the photodiode PD 21 is cut off by the forced cut-off signal 7a.

Abstract: PURPOSE:To enable to automatically set bridging members simultaneously with the opening and closing of a rear gate by a structure wherein the bridging member slide down backward by gravity when the rear gate is open and return to their original states by gravity when the rear gate is closed. CONSTITUTION:When a piston rod 9 is retreated under the state that the rear gate 2 is closed, the rear gate 2 is pivoted backward about a hinge 5. At this time, the bridging members 3 and 3' move downward and backward in such a manner as to slide down along the backward inclination of the rear gate 2. When the piston rod 9 is stretched under the above-mentioned closed state of the rear gate 2, the rear gate 2 is pivoted upward about the hinge 5 in order to be closed and the bridging members 3 and 3' are also pivoted upward integrally with the rear gate 2. Because the bridging members are automatically set simultaneously with the opening and closing of the rear gate in such a manner as mentioned above, the loading and unloading of cars are simplified.
