Abstract: PURPOSE:To reduce the amount of solder left on connecting terminals of a mounting device side when a chip is removed after it was adhered by making connecting terminals connected with conducting patterns on a board connected with chip side connecting terminals into wire shapes of small contact area. CONSTITUTION:The connecting terminals 13 of a printed board 11 are connected with connecting terminals on the back face of the board by conducting patterns 12 via through holes 14, and board side terminals 13 that are connected with terminals corresponding to power source terminals among the chip side hemispherical connecting terminals 16 of a chip 17 are also connected with connecting terminals 15 for a connector by the conducting patterns 12. Then the chip 17 is mounted onto the board 11, a power source is connected to the connector terminals 15 and inspection and ageing are carried out. As these terminals 15 have a hemipherical shape formed of wire with small contact area, the amount of solder left on the receiving device side connecting terminals when the chip is removed after it was adhered to the mounting device can be reduced.

Title: Dynamic amount sensor
Inventor: TAMURA MASAMI
IPC: G01P21/00
Filed: 1995-05-08
Abstract: PURPOSE: To obtain a dynamic amount sensor which can be miniaturuzed and whose sensitivity and accuracy can be made high by a method wherein a servo current is made to flow so as to cancel a magnetic-field change due to the displacement of a moving part and a voltage which is proportional to the servo current is output. CONSTITUTION: A magnetic-field servo-current passage 6 is formed on a substrate 5. When an acceleration acts, a composite magnetic field by a magnetic field which is generated from a magnetic-field generation source 3 and which uses a moving part 1 and a fixed part 2 as a magnetic path and by a magnetic field due to the servo current of the current passage 6 is input to magnetic sensors 4. Then, a current in the direction of (b) is supplied to the current passage 6 in such a way that a servo magnetic field (c) whose magnitude is identical to that of the change portion (a) of an input magnetic field and whose direction is opposite is generated by a control circuit. Then, a voltage which is proportional to its current value is output as a sensor output.  In this case, a final output which is proportional to a magnetic-field servo current becomes linear with reference to an input acceleration. As a result, a magnetic sensor which is nonlinear and whose sensitivity is high can be used, and it is possible to obtain a dynamic amount sensor which is small and whose accuracy and sensitivity are high.
