摘要： A method for the inspection of a circuit board, capable of precisely detecting deviation in position between the electrodes to be inspected of a circuit board and the inspection electrodes of a tester, thereby achieving fine alignment between the two, with high reliability. The method includes repeating, in two different axial directions, the measurement of conduction state between the electrodes to be inspected of a circuit board and the inspection electrodes of a tester each time changing, by a small distance, the relative position of the inspection electrodes portion of the tester and the circuit board, to detect a position of high conduction state and two positions of low conduction state which are distant from the position and located so that the position is held between them, in each of the two directions. From the information thus obtained, determining the desired connection position in which the inspection electrodes are to be in the highest conduction state in relation to the electrodes to be inspected in one or both of the directions. And then, moving the inspection electrodes portion relatively to the circuit board to place the inspection electrodes in the desired connection position.

摘要： A process for producing an anisotropically electroconductive sheet having a plurality of electroconductive portions extending in the direction of the thickness of the sheet, including the steps of forming a layer of a molding material consisting of a mixture of electroconductive particles and a high-molecular-weight substance in a cavity of a mold consisting of a pair of upper and lower molds and applying an anisitropic magnetic field to the molding material layer when a space is present between the molding surface of the upper mold and the molding material layer, to fluidize the molding material and simultaneously move the electroconductive particles in the molding material to areas where the magnetic field is applied, thereby allowing the electroconductive particles to gather in said areas to form the electroconductive portions including projecting portions.
