Title: Soldering check method of pad lead-type lsi terminal
Inventor: SUZUKI NOBUYUKI
IPC: G01N21/956
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To check whether all terminals are correctly soldered to lands provided on a printed wiring board by providing a means for measuring the temperature of the corresponding through-holes on the rear surface of the printed wiring board. SOLUTION: An LSI main body 1 is uniformly heated by a hot water bag 13. The temperature do through-holes 5 of a PWB 3 corresponding to the terminals 2 of the LSI main body 1 is measured from behind the PWB 3 and displayed by an infrared sensing imaging device 7 composed of an infrared camera 8, a photosensor 9, and a computer imaging device. Hot water of 200cc or so kept at a temperature of 70 to 90 deg.C is poured into a hot watar bag 13, and the bag 13 is put on the LSI main body 1 to heat it uniformly. Heat is transmitted to the terminals 2 of the LSI main body 1, then copper foil lands and the corresponding through-holes 5.  Then, the temperature rise rate of the corresponding through-holes 5 on the rear side is measured and compared with that of a normal through-hole 5, whereby it can be found whether solder is firmly attached to a land or loosely attached to a load to make a lead terminal floating.

Abstract: PURPOSE:To obtain the titled device which is easy of manufacture and has a high mass-productivity with high reliability by a method wherein the third substrate having a recess is provided, and a sensor substrate and a matrix substrate are fixed in this recess, which is then closed with a lid. CONSTITUTION:The substrate 11 has a recess 12, in which the sensor substrate 2 and the matrix substrate 3 are fixed at the bottom. The sensor substrate 2 is provided with a photoelectric conversion element C which receives light through an aperture (a) provided in the substrate 11.

Title: Overload protecting device
Inventor: NISHIDA KAZUSHI
IPC: H02H3/08
Filed: 1980-10-29
Abstract: PURPOSE:To prevent the burning of an overload protecting device due to a short circuit or an overload, by providing a means to detect the voltage drop between the connection lines of a DC constant voltage power supply and a load. CONSTITUTION:When a high current higher than a rated level flows to a load 2 due to a short circuit of an electric circuit or other factors, the interline voltage V'C increases between a DC constant voltage source 1 and the load 2. This voltage V'C is amplified by a differential amplifier 31 and applied to an input terminal of a comparator 33 to be compared with the reference voltage VB applied to the other input terminal. In such way, VC>=VB is detected. Thus the comparator 33 supplies a protection command signal SP to a constant voltage control part 14 of the power supply 1. As a result, the part 14 discontinues the pulse generation of an intermittent control pulse generating circuit and then turns off a switching transistor 12 consecutively. As a result, the DC output of the power supply 1 is stopped to prevent an abnormal supply of current to the load 2.
