PROCESS OF MANUFACTURE OF THIN-FILM TRANSDUCER Russian patent published in 2004 - IPC

FIELD: instrumentation. SUBSTANCE: invention is aimed at technology of manufacture of instrumentation aids and development of threshold pressure transducers. Proposed thin-film transducer consists of two layers. First layer is made of flexible dielectric material, second layer is formed on it with the usage of solid metal sheet. Then elements of transducer are assembled to produce package of alternating first and second layers. Package is connected under conditions of thermal treatment under pressure. Package in this case is positioned with the help of two auxiliary elements between two dielectric layers used as walls of transducer laminated on one side bordering on package. One auxiliary element is made of metal rubber, the other element is produced from ductile metal sheet. Preforms of current-conducting element are cut out before assembly, they are applied on dielectric optically clear layer laminated on two sides so that these current-conducting profiles match. Thermal treatment is carried out for simultaneous connection of all layers of package. Second auxiliary perform comes in the form of layer 0.5-1.0 mm thick placed on side of assembled package of transducer put on measured object. EFFECT: simplified design, enhanced operational reliability of transducer, raised resistance to vibration and impact effects. 1 dwg, 1 tbl
