Abstract:
The present invention relates to label, device, system and method for sorting bolts, bars, pins, studs, dowels, screws or the like (collectively and individually described herein as a bolt). The bolts are being characterized by a first and a second dimension. The identification system comprises a color chart defining all ten numerals and most commonly used bolt diameters corresponding to various colors and an identification label. The identification label comprises a main section and at least one other section being both adapted to receive at least one color and/or a numeral. Each combination of a color and a numeral being defined by the color chart. The combination of colors and/or numerals of the main section defines the first dimension of the bolt and the combination of colors and/or numerals of the at least one other section defines the second dimension of the bolt.
Abstract:
A 3D electronic module including, in a direction referred to as the vertical direction, a stack of electronic dice, each die including at least one chip provided with interconnect pads, this stack being attached to an interconnect circuit for the module provided with connection bumps, the pads of each chip being connected by electrical bonding wires to vertical buses that are themselves electrically linked to the interconnect circuit for the module, a bonding wire and the vertical bus to which it is linked forming an electrical conductor between a pad of a chip and the interconnect circuit, wherein each electrical bonding wire is linked to its vertical bus by forming, in a vertical plane, an oblique angle and in that the length of the bonding wire between a pad of a chip of one die and the corresponding vertical bus is different than the length of the bonding wire between one and the same pad of a chip of another die and the corresponding vertical bus, and this is obtained by wiring the bonding wire in a non-rectilinear manner to compensate for the difference in vertical length of the vertical bus from one die to the other, such that the electrical conductor between the pad of a chip of one die and the interconnect circuit, and the electrical conductor between the same pad of a chip of the other die and the interconnect circuit, are the same length.
Abstract:
A method of collective fabrication of 3D electronic modules, each 3D electronic module comprising a stack of at least two, surface transferable, ball grid electronic packages, tested at their operating temperature and frequency comprises: a step of fabricating reconstituted wafers, each reconstituted wafer being fabricated according to the following sub-steps in the following order: A1)) the electronic packages are placed on a first sticky skin, balls side, B1) molding of the electronic packages in the resin and polymerization of the resin, to obtain the intermediate wafer, C1) thinning of the intermediate wafer on the face of the intermediate wafer opposite to the balls, D1) removal of the first sticky skin and placing of the intermediate wafer on a second sticky skin, side opposite to the balls, E1) thinning of the intermediate wafer on the balls side face, F1) formation of a balls side redistribution layer, G1) removal of the second sticky skin to obtain a reconstituted wafer of smaller thickness than the original thickness of the electronic packages, several reconstituted wafers having been obtained on completion of the previous sub-steps, stacking of the reconstituted wafers, dicing of the stacked reconstituted wafers to obtain 3D modules.
Abstract:
L'invention concerne un procédé de dépôt en phase liquide de couches métalliques dans des trous (11) d'un module électronique (10) disposé dans une enceinte hermétique (1), à partir d'un liquide (4) chimique à composés métalliques destinés à former une couche métallique. Les trous ont une profondeur P et un diamètre D tels que D>80 µm et P/D > 10, et le procédé comporte au moins un cycle (Cyc) comportant les sous-étapes suivantes : - M1) Mise sous une pression prédéterminée P0 de l'enceinte et remplissage de l'enceinte par le liquide, - M2) Dégazage des trous par mise sous une pression réduite P1 de l'enceinte, avec P1
