Abstract:
A circuit board, having:an insulation board having first and second opposite main faces; a plurality of first strip bus bars of substantially a same length, at least one first strip bus bar having a first preformed bent portion, arranged on said first main face and extending in parallel in a first direction; and a plurality of second strip bus bars of substantially a same length, at least one second strip bus bar having a second preformed bent portion, arranged on said second main face and extending in parallel in a second direction crossing said first direction, whereby as seen in plan view on one of said main faces there is an array of crossing points of said bus bars; wherein a pitch spacing between one of the plurality of first strip bus bars and the plurality of second strip bus bars is variable whereas the pitch spacing between the other of the plurality of first strip bus bars land the plurality of second strip bus bars is uniform, and said insulation board has at least one hole through it at at least one of said crossing points, and at least one of said at least one hole the first and second preformed bent portions of said at least one first strip bus bar and said at least one second strip bus bar are bent each towards the other and are mutually joined to establish electrical connection between them, whereby a predetermined wiring pattern is obtained.
