Title: Inspecting method of joined state of lead in tab
Inventor: FUKUCHI YASUHIKO
IPC: G01N33/00
Filed: 1988-02-24
Abstract: PURPOSE:To enable the sure and easy detection of imperfection of joining,by a method wherein a connected part of a lead and a bump of a tab being in contact with a stage for inspection is sucked by vacuum so that it can be displaced in the direction of exfoliation of the joining. CONSTITUTION:On the occasion of inspection of a tab, a vacuum suction device 7 is adjusted to be of negative pressure in accordance with the kind of the tab, and a film 4 around an LSI chip of the tab being in contact with a stage 5 with a gasket 6 interposed therebetween is sucked by applying thereon the negative pressure adjusted by opening a leak valve 14, through holes 9 and 10. By this suction, the film 4 is brought into close contact with the gasket 6 and fixed thereon. With a leak valve opened, subsequently, the same negative pressure as applied on the film 4 is applied onto the back of the chip 1 through a pipe 11 and holes 12 and 13 so that a suction is made in the direction in which the connection of the chip 1 with a bump 2a and a lead 3a is exfoliated. On the occasion, the surface 5a of the stage being opposite to the chip 1 and the surface 6a of the gasket 6 are displaceable onto the gasket 6 side by a certain distance (t) from the stage 5 and the gasket 6. Therefore, a connected part in a state of imperfect joining, such as a one of a lead 3b and a bump 2b, is exfoliated by the distance (t).

Abstract: PURPOSE:To quantitatively evaluate the picture quality by inputting a periodical reference pulse signal to a signal recording and reproducing system as an evaluation object and comparing a signal part, which will be set to a secand luminance level, with the threshold in a prescribed level set between first and second luminance levels in case of no signal deterioration. CONSTITUTION:A pulse signal S2 from a video signal processing system 2 is inputted to a clamping circuit 8 also and is clamped at a certain signal level and is inputted to a gate circuit 9. A signal S4 outputted from the gate circuit 9 is inputted to a comparator 10 and has the level compared with the threshold in a prescribed level. A comparison signal S5 outputted from the comparator 10 is inputted to a waveform shaping circuit 12 and is converted to a short- period pulse signal S6 and is inputted to a counter 13. The number of pulses of this signal is counted by the counter 13, and the counted value is displayed on a display device 14. Since this counted value indicates the number of normal square wave pulses, signal deterioration is small and a signal recording and reproducing system 2 is judged as good if the counted value is larger than a prescribed value.
