Abstract
The invention relates to a heat-peelable pressure-sensitive adhesive sheet for cutting a laminated ceramic sheet and a method for cut-processing a laminated ceramic sheet. The heat-peelable pressure-sensitive adhesive sheet for cutting a laminated ceramic sheet is used for temporary fixing at cutting of the laminated ceramic sheet, and includes a base material and, formed on at least one surface of the base material, a heat-expandable pressure-sensitive adhesive layer containing a pressure-sensitive adhesive, a foaming agent and a tackifying resin, in which the heat-expandable pressure-sensitive adhesive layer has a gel fraction of 50% by weight or more, and the base polymer of the pressure-sensitive adhesive forming the heat-expandable pressure-sensitive adhesive layer has an acid value of 350mg-KOH / g or less and the tackifying resin contained in the heat-expandable pressure-sensitive adhesive layer has an acid value of 80mg-KOH / g or less.
Description
technical field The present invention relates to a heat-peelable pressure-sensitive adhesive sheet for cutting a laminated ceramic sheet and a method for cutting and processing a laminated ceramic sheet using the heat-peelable pressure-sensitive adhesive sheet. Background technique The recent demand for electronic components is miniaturization and precision of the components themselves. For example, in ceramic capacitors, typified by so-called "0603" or so-called "0402", miniaturization and high-capacity formation through high-level lamination of layers exceeding several hundred or more have become remarkable. In particular, in the field of lamination of prebaked sheets (green sheets) of ceramics such as ceramic capacitors, precision in processing is increasingly required for miniaturization and precision. For example, as an example of a method for producing a ceramic capacitor, a production method including the following steps is mentioned: (1) a step of printing electrod...
