Title (EN) HOT PRESSING CERAMIC DISTORTION CONTROL
(FR) COMMANDE DE LA DISTORSION DE LA CERAMIQUE FORMEE A CHAUD
Abstract: front page image
(EN)A method to control the post sinter distortion of hot pressing sintered multilayer ceramic laminate (100) by placing a non-densifying structure (40) in the green ceramic laminate (100) prior to sintering. One or more non-densifying structures (40) are placed on one or more ceramic greensheets (10) which are then stacked and laminated to form a green ceramic laminate (100). The laminate is then sintered and the non-densifying structure (40) will control the dimensions of the hot pressed, multilayer ceramic substrate. The method can be used to control post sinter dimensions in MLC substrates manufactured as either singular multi-up substrates by placing the non-densifying structure (40) in the kerf area (30) between the individual product ups prior to sintering.
(FR)Un procédé de commande de la distorsion ayant lieu après le frittage d'un stratifié céramique multicouche fritté est formé à chaud (100) utilisant le positionnement d'une structure de non densification (40) dans le stratifié céramique frais (100) avant le frittage. Une ou plusieurs structures de non densification (40) sont placées sur une ou plusieurs feuilles céramiques fraîches (10) qui sont ensuite empilées et stratifiées afin de former un stratifié céramique frais (100). Le stratifié est ensuite fritté et la structure de non densification (40) va surveiller les dimensions du substrat céramique multicouche formé à chaud. Le procédé peut servir à surveiller les dimensions après frittage dans des substrats MLC fabriqués comme simple ou multiples substrats par le positionnement de la structure de non densification (40) dans le trait de chalumeau (60) entre les parties supérieures du produit individuelles avant le frittage.
