摘要： A microactuator is attached to a first face of a coupling formed on a suspension, so that an R/W transducer projects from an opposite face. A hole in the coupling permits passage of an adhesive mass interposed between a rotor of the microactuator and the R/W transducer. A strip of adhesive material extends between a die accommodating the microactuator and the coupling, and externally surrounds the microactuator. The coupling acts as a protective shield for the microactuator, both mechanically and electrically. The coupling covers the microactuator at the front, and prevents foreign particles from blocking the microactuator. In addition, the coupling electrically insulates the R/W transducer, which is sensitive to magnetic fields, from regions of the microactuator biased to a high voltage. With the coupling, the strip forms a sealing structure, which in practice surrounds the microactuator on all sides.

摘要： To reduce the risk of breakage of the moving parts of an integrated microstructure during manufacture steps causing mechanical stresses to the moving parts, a temporary immobilization and support structure is formed, whereby a moving region of the microstructure is temporarily integral with the fixed region. The temporary structure is removed at the end of the assembly operations by non-mechanical removal methods. According to one solution, the temporary structure is formed by a fusible element removed by melting or evaporation, by applying a sufficient quantity of energy thereto. Alternatively, a structural region of polymer material is formed in the trench separating the moving part from the fixed part, or an adhesive material layer sensitive to ultraviolet radiation is applied.
