Patent CA-2453003-C (CA)
Inventor: ROSS RICHARD J
IPC: H01L21/30
Filed: 2002-06-19
Granted: 2009-12-22
Abstract: L'invention concerne des dispositifs (dés) de circuit semi-conducteurs incorporés dans des assemblages électroniques impénétrables par l'humidité en formant des enveloppes autour du dé en trois sections séparées, base, parois et couvercle. Le dé se trouve d'abord soudé ou alors relié à la base, ensuite vient la fixation des parois à la base et enfin, le couvercle est attaché aux parois. Dans le cas des procédés impliquant une base thermoconductrice et une température de soudage élevée, on peut fixer le dé à la base à la température de soudage élevée, ensuite on applique les parois à la base à une température très inférieure, en évitant un éventuel dégât à température élevée infligé aux parois. Les parois plastiques qui seraient alors détériorées ou distordues lors de l'exposition à une température de soudage élevée peuvent alors être utilisées. Dans le cas des assemblages électroniques en général, l'utilisation de parois plastiques permet d'utiliser des combinaisons de matériaux pour le couvercle et la base qui seraient autrement incompatibles et réduit ou supprime l'incidence d'une panne causée par les fractures de tension qui se produisent au cours de phases à température élevée rencontrées lors de la fabrication, l'assemblage, le test et l'utilisation dudit assemblage.

Abstract: The present invention provides a slip system for fractionally engaging a temporarily set body, such as a packer or a whipstock, within a wellbore. The slip system comprises (1) a plurality of slips: (2) a tubular slip ring for holding the individual slips at an end; and (3) a tubular cone body having beveled surfaces for receiving the individual slips when the slip system is actuated. Each slip has a first end that defines a tail, and a second opposite end that defines a slip body.  The tail and the slip body are integral, meaning that the intermediate shank portion of prior art slips is essentially removed. In its place, a dovetail geometry is provided within the tail, creating an increased tail width at the end of the rail opposite the slip body. The slip ring has a plurality of pockets, with each pocket being dimensioned to receive the dovetailed configuration of the tail on the respective slips.
