Abstract:
A method for fabricating a semiconductor component with a through wire interconnect includes the step of providing a substrate having a circuit side, a back side, and a through via. The method also includes the steps of: threading a wire through the via, forming a contact on the wire on the back side, forming a bonded contact on the wire on the circuit side, and then severing the wire from the bonded contact. The through wire interconnect includes the wire in the via, the contact on the back side and the bonded contact on the circuit side. The contact on the back side, and the bonded contact on the circuit side, permit multiple components to be stacked with electrical connections between adjacent components. A system for performing the method includes the substrate with the via, and a wire bonder having a bonding capillary configured to thread the wire through the via, and form the contact and the bonded contact. The semiconductor component can be used to form chip scale components, wafer scale components, stacked components, or interconnect components for electrically engaging or testing other semiconductor components.

A printed circuit board with a quartz crystal oscillator includes a mounting area for receiving the quartz crystal oscillator, two first vias, and two second vias. A copper foil is arranged on the mounting area. Pins of the quartz crystal oscillator are inserted into the first vias. The second vias are connected to a ground layer of the PCB and communicate with the copper foil, for transmitting noise of the quartz crystal oscillator to the ground layer of the PCB.
Abstract:
After respective one ends of lead wires are fixed to a printed circuit board, the lead wires are bent, the printed circuit board is brought into a case and the other ends of the lead wires are bonded to terminals of the case. Since the lead wires are processed before the substrate is brought into the case, this eliminates the necessity to perform formation of the bent portions of the lead wires and fixing of the lead wires to the substrate in a narrow space of the case and allows simplification of bonding operation. Thus provided is a lead wire bonding method for bonding lead wires with bent portions to the substrate, which simplifies a bonding operation.

A first board, on which electric wires are wired, includes a first part having a first thickness and a second part continued from the first part and having a second thickness smaller than the first thickness. A second board, on which bus bars are arranged, is disposed on the second part of the first board. The second board has a third thickness which is determined such that an additional thickness of the second thickness and the third thickness is not greater than the first thickness.
Abstract:
The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package, that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a plated rivet-shaped connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.
