Abstract:
The present invention relates to a method for producing a conductor structural element, comprising providing a rigid substrate, electrodepositing a copper coating on the rigid substrate, applying a conductor pattern structure to the copper coating, then possibly mounting components, laminating the substrate with at least one electrically insulating layer, detaching the rigid substrate, at least partially removing the remaining copper coating of the rigid substrate in such a way that the conductor pattern structure is exposed.
Abstract:
Wirebond protection is provided for imaging tiles in which the imaging sensor and PCB are mounted side-by-side on a tile carrier for use in X or Gamma Ray indirect imaging detectors without use of a “glob top” encapsulant. A glass cap comprising a bead of adhesive material and a lid is formed to provide an enclosed open-air cavity around the wire bonds. As such, any expansion of the bead material does not produce mechanical stress on the wire bonds.
Abstract:
The present invention provides systems and methods for creating interlayer mechanical or electrical attachments or connections using filaments within a three-dimensional structure, structural component, or structural electronic, electromagnetic or electromechanical component/device.
Abstract:
An electrical device includes a first electrical component and a second electrical component connected to each other via an electrical connection having an electrically insulating support plate and a weld joint deposited on the support plate. The weld joint has a melting temperature (Ta) significantly lower than an ambient operating temperature (Ta) to which at least one of the two electrical components and the electrical connection are subjected. The electrical device includes cement that completely covers the exposed weld joint. The material of the cement is chosen to maintain its adhesion and its tightness with respect to the weld joint when the Ta is applied.
Abstract:
An embodiment of an electronic device includes a circuit component (e.g., a transistor or other component) coupled to the top surface of a substrate. Encapsulation is formed over the substrate and the component. An opening in the encapsulation extends from the encapsulation top surface to a conductive feature on the top surface of the component. A conductive termination structure within the encapsulation opening extends from the conductive feature to the encapsulation top surface. The device also may include a second circuit physically coupled to the encapsulation top surface and electrically coupled to the component through the conductive termination structure. In an alternate embodiment, the conductive termination structure may be located in a trench in the encapsulation that extends between two circuits that are embedded within the encapsulation, where the conductive termination structure is configured to reduce electromagnetic coupling between the two circuits during device operation.

A flexible display apparatus including a flexible display panel, at least one flexible circuit board, at least one driving chip, and a sealing layer is provided. The flexible display panel has a display area and a bonding area located outside the display area. The flexible circuit board is disposed in the bonding area of the flexible display panel. The driving chip is disposed on the flexible circuit board. The sealing layer encapsulates a periphery of the flexible display panel and extendedly covers the bonding area and a portion of the flexible circuit board.
Abstract:
A semiconductor package includes a printed circuit board (PCB), a chip bonded to the PCB, a mold protecting the chip and exposing a backside surface of the chip, via openings extending in the mold to expose first contacts bonded to the PCB, and at least one first marking inscribed in a marking region of the mold between the backside surface of the chip and the vias. The mold has an exposed molded underfill (eMUF) structure covering the sides of the chip while exposing the backside surface of the chip. A PoP package includes a top package stacked on and electrically connected to the semiconductor package.
Abstract:
Methods are provided for making embedded Wafer-Level Packaging (eWLP) devices, packages and assemblies. The eWLP methods allow back side electrical and/or thermal connections to be easily and economically made at the eWLP wafer level without having to use thru-mold vias (TMVs) or thru-silicon vias (TSVs) to make such connections. In order to create TMVs, processes such as reactive ion etching or laser drilling followed metallization are needed, which present difficulties and increase costs. In addition, the eWLP methods allow electrical and optical interfaces to be easily and economically formed on the front side and/or on the back side of the eWLP wafer, which allows the eWLP methods to be used to form optoelectronic devices having a variety of useful configurations.
Abstract:
Delamination of stacked integrated circuit die configurations on printed circuit boards is avoided by providing a metal trace support structure underneath the die stack. The metal trace support structure features substantially equally spaced thin metal traces in place of a contiguous metal plate which has been used in the past. Spaced apart thin metal traces are less vulnerable to thermal expansion than a metal plate which has a large thermal mass. The metal traces still provide structural stability, while preventing delamination of the die stack configuration during thermal processing. A method of attaching a bridge die stack configuration to a printed circuit board by adhering a die attach film to a field of metal traces is demonstrated. In addition, the electrical and structural integrity of the bridge die stack formed with a metal trace support structure is confirmed with test results.

In a method for manufacturing a multilayer ceramic electronic device, a multilayer ceramic element assembly including laminated unsintered ceramic base material layers, a first conductor pattern, a seat portion disposed in a surface of the multilayer ceramic element assembly and arranged to mount a surface mount electronic device thereon, a second conductor pattern connected to the surface mount electronic device, and a resin introduction portion located outside a vertically projected region of the surface mount electronic device and arranged to introduce a resin to the seat portion is prepared. The multilayer ceramic element assembly is fired and the surface mount electronic device is mounted on the seat portion of the fired multilayer ceramic element assembly with the second conductor pattern therebetween. The resin is filled from the resin introduction portion into the seat portion and between the seat portion and the surface mount electronic device and is cured.
