Adhesive lamination useful in making circuit board structures

摘要

An adhesive lamination has patches of an adhesive layer which correspond to predetermined positions on a plurality of circuit boards, and the adhesive layer is applied across the plurality of circuit boards. This adhesive lamination is composed of a first separation sheet, a second separation sheet and the adhesive layer interposed between the first and second separation sheets. A number of patches of the adhesive layer are formed on the first separation sheet and arranged so that the length of the patch of the adhesive layer is approximately parallel to the short side of the first separation sheet.
