Abstract: Un système de réfrigération (10) par dilution d'hélium, pouvant fonctionner pendant un temps limité et recyclable pour une prochaine période de fonctionnement, est compacte avec un système de pompage et des appareils de chauffage (38) autonomes destinés à faire fonctionner ledit système (10). Une chambre de mélange (60) contient du 3He et du 4He liquides qui sont refroidis au préalable par un récipient (42) couplé contenant du 3He liquide, ce qui permet la séparation de phase entre une phase liquide riche en 3He et une phase liquide de 3He-4He dilué qui conduit à l'étape final d'un processus de refroidissement par dilution pour l'obtention de températures basses. La chambre de mélange (60) et un appareil de distillation (58) sont couplés par une conduite (63) pour fluide et sont maintenus sensiblement au même niveau, la section transversale de l'appareil de distillation (58) étant plus petite que celle de la chambre de mélange (60). Cette configuration permet d'obtenir une puissance et une efficacité de refroidissement maximum, étant donné que la période de refroidissement se termine lorsque la chambre de mélange (60) est vidée du 3He liquide, la chambre de mélange (60) ne contenant ainsi pratiquement plus d'hélium liquide, ce qui permet d'éviter un refroissement superflu et inefficace d'une grande quantité de 3He-4He dilué en phase liquide.

IPC: H05K1/02
Filed: 1989-02-03
Abstract: The invention relates to laminated printed circuit boards and to a method of fabricating a printed circuit board having improved circuit board performance. The circuit board utilizes low dielectric materials having dielectric constants of less than 3.0. The dielectric layers (12a,12b) are spaced apart from plated through-holes, thus eliminating the interface between the metallized surface (16) of the through-hole (15) and the dielectric sheet (12). Thus, the low dielectric layer is not required to be plated. 
     The lower dielectric character of the laminates improves wiring density, circuit speed, and provides for thinner laminates and cores.
