<p>PURPOSE:To alter the interval of wirings to be tested irrespective of the thickness and the pitch of the wirings by varying the size or pitch of repetitive base unit for upper wiring and lower structure and adding folding lines of 45 deg. to parallel straight lines. CONSTITUTION:If the sizes are different between a base unit 61 of the primary layer and the base unit 62 of upper wirings, the units are repetitively superposed to increase the number of the cases of taking the upper wirings with respect to the primary layer. A straight line of 45 deg. is used in addition to parallel straight lines to alter the interval between the lines 71, 72 and a folding line 73. Further, the first and second wirings 81, 82 are formed with one base unit for three cases of parallel, 45 deg. and perpendicular.</p> |
