Abstract:
Electrical components mounted onto a circuit board may be sealed within a frame tray upon the addition of a curable material that encapsulates the circuit board. The electrical components of the circuit board are positioned and sealed within the frame tray such that the cured material does not affect an airflow path which dissipates heat produced by the electrical components during use. The curing of the curable material shields the circuit board from moisture, dust and other environmental contaminates.
Abstract:
Multiple DIMM circuits or instantiations are presented in a single module. In some embodiments, memory integrated circuits (preferably CSPs) and accompanying AMBs, or accompanying memory registers, are arranged in two ranks in two fields on each side of a flexible circuit. The flexible circuit has expansion contacts disposed along one side. The flexible circuit is disposed about a supporting substrate or board to place one complete DIMM circuit or instantiation on each side of the constructed module. In alternative but also preferred embodiments, the ICs on the side of the flexible circuit closest to the substrate are disposed, at least partially, in what are, in a preferred embodiment, windows, pockets, or cutaway areas in the substrate. Other embodiments may only populate one side of the flexible circuit or may only remove enough substrate material to reduce but not eliminate the entire substrate contribution to overall profile. The flexible circuit may exhibit one or two more conductive layers, and may have changes in the layered structure of have split layers. Other embodiments may stagger or offset the ICs or include greater numbers of ICs.
Abstract:
In one embodiment, a package-to-package stack is assembled comprising a first integrated circuit package, and a second integrated circuit package which are mechanically and electrically connected using an interposer. In one embodiment, the interposer 106 includes columnar interconnects which may be fabricated by etching a conductive member such as copper foil, for example. In one application, the pitch or center to center spacing of the columnar interconnects may be defined by masking techniques to provide an interconnect pitch suitable for a particular application. In yet another aspect, etching rates may be controlled to provide height to width aspect ratios of the columnar interconnects which are suitable for various applications.
Abstract:
A motherboard may have contact pads arranged along a peripheral region on one or both surfaces thereof. A memory module may have unit packages fixed to an upper plate and a lower plate of a module frame. The unit packages may be spaced apart from each other. The upper and the lower unit packages may have contact terminals facing each other. The contact terminals may be elastically bendable, and/or the unit packages may be mounted on the plates via elastic members. The peripheral region of the motherboard may be inserted into the memory module, so the contact terminals of the memory module may elastically contact with and be electrically coupled to the contact pads of the motherboard.
