Delaminations are a principal quality problem in the manufacture of multilayer ceramic capacitors (MLC's). They are defined as a separation of the electrode and dielectric layers and can result in electrical shorts and/or life failures. Delaminations originate from many sources in MLC manufacture, but we have identified four which are caused by the electrode. High levels of organic resin in the electrode paste lead to high resin content in dried electrode prints, requiring removal of large amounts of organic residues during burnout, causing delaminations. Catalysis of these organics by the precious metals also causes delaminations from rapid evolution of gas and heat release during burnout. Poor adhesion of the dielectric tape layers to dried electrode prints during MLC buildup can cause "green-state" delaminatious which remain through firing. Sintering shrinkage mismatch between the electrode and dielectric layers leads to internal stresses in MLC's, resulting in delaminations. We discuss these electrode-based mechanisms of delamination and the design of electrode pastes which solve these problems. [
The idea of ‘collective memory’ features prominently in several disciplines but rarely in legal scholarship. Drawing on the work of Henri Bergson, Maurice Halbwachs and GWF Hegel, this paper seeks to present an account of collective memory that is relevant to discourse on law and policy. The paper uses the example of the policy response to the European sovereign debt crisis as a means of illustrating how collective memory of events in the distant past can shape individual behaviour and thinking. It argues that the current policy response can be explained, at least in part, by the influence on policy makers of the standard historical narrative of the Great Inflation of Weimar Germany. When, however, collective memory takes the form of Bergsonian ‘habit memory’, it can inhibit our efforts to resolve hard cases and the German government's opposition to the European Central Bank acting as a lender of last resort in the government bond markets neatly illustrates this point. If the debt crisis is to be managed effectively, policy makers must draw on Bergsonian ‘pure memory’ to explore the bounds of political and economic possibility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
