Abstract:
An adhesive lamination for application across a circuit board chain comprising:a multiple number of first separation sheets of an approximately rectangular shape; a plurality of rectangular shaped patches of an adhesive layer disposed on each of the first separation sheets at evenly spaced intervals such that the long sides of the plurality of patches are approximately parallel with the short sides of the first separation sheets; a second separation sheet positioned such that the plurality of rectangular shaped patches are disposed between the plurality of first separation sheets and the second separation sheet; the patches being provided in numbers and being arranged at intervals such that, when each of the first separation sheets is applied across a circuit board chain, in which a plurality of circuit boards of an elongated rectangular shape are separably joined along their long sides at said evenly spaced intervals, and the first separation sheets are applied in a direction perpendicular to the long sides of the plurality of circuit boards, the plurality of patches from each of the first separation sheets are distributed with one patch per circuit board in the circuit board chain.
