PURPOSE:To facilitate the positioning of probe pins relative to electrodes by a method wherein a board provided with guide holes through which probe pins are inserted to abut against corresponding electrodes when determining characteristics of a hybrid IC circuit and the like is located over said circuit. CONSTITUTION:This relates to a method of holding the tips of probe pins 2 provided in a block 3 made of a colorless transparent acrylic board 1 facing the electrodes 8 provided in a large number on the surface of a circuit substrate 9 made of a ceramic board 7. That is, a guide board 6 made of an acrylic board 4 made of the same material constituting the acrylic board 1 and provided with a number of guide holes 5 corresponding respectively to the electrodes 8 is positioned between the block 3 and the substrate 9. The electrodes 8 are positioned so that they may be exposed in the guide holes 5 through which the tips of the pins 2 gain access to and abut against the opposite electrodes 8. The empolyment of the guide board 6 facilitates the proper positioning of the pins 2 to contact the electrodes 8. |
