Abstract:
The invention refers to a tip to mount or repair printed circuit board lines, designed as an accessory to the electronic circuit wiring device described in Patented Invention 538.302. This tip includes a means of attachment to this device intended to substitute the latter's classic tip, at the free end of which device the flat tip itself is located whose section is equal to that of a thin band of tin coated copper designed to be the wiring element to obtain or repair circuit lines, fed by a reel attached to the device.

Abstract:
Disclosed is a method for repairing opens (12) in thin film conductor lines (11) on a substrate (10), preferably a multilayered ceramic substrate. An unpatterned repair metal film (20) is placed over a general area of open defects (12) in conductive lines (11) on a substrate (10). Preferably, this metal is placed over the conductive lines and opens therein by decal transfer. The assembly is then heated to cause diffusion bonding between the repair metal (20) and conductive lines (11), but not between the repair metal (20) and substrate (10). After diffusion bonding, the structure has metal bridges formed across any open defects covered by the repair film and also between adjacent conductive lines. The area of repair is then subjected to ultrasonic energy in a liquid ambient for a time at least long enough to remove metal bridges between adjacent conductive lines, but less than that required to remove repair metal bridges over the opens in the conductive lines. The resultant structure has metal bridges spanning opens in the conductive lines, and no metal bridges between adjacent conductive lines.
Abstract:
In accordance with an aspect of the present disclosure, a contact structure for an electronic device may include a printed circuit board (PCB) including at least one hole vertically formed through the PCB, a housing (e.g., a mechanical part) on which the PCB is seated, and a contact element, at least part of which is brought into contact with the housing disposed on a side of the hole of the PCB and below the same. The contact element may include a contact part soldered on a peripheral portion around the hole, and a protrusion passing through the hole and making contact with the housing disposed below the PCB.
Abstract:
The joint structure includes: a junction box configured to connect an internal circuit of an apparatus and an external conductor to each other; a metal electrode being in the junction box and to be joined to the external conductor; and a flexible printed circuit in a strip shape, the flexible printed circuit forming the internal circuit and having an end portion to be joined to the metal electrode. The metal electrode has a joint portion to be joined to the end portion in a superposed manner, and the joint portion in a free and lone state before being superposed on the end portion is ensured to have a gap greater than the thickness of the end portion (including solder), between the joint portion and its opposed surface, and has movability toward the opposed surface side when the joint portion is pressed.
Abstract:
Buffer structures are provided that can be used to reduce a strain in a conformable electronic system that includes compliant components in electrical communication with more rigid device components. The buffer structures are disposed on, or at least partially embedded in, the conformable electronic system such that the buffer structures overlap with at least a portion of a junction region between a compliant component and a more rigid device component. The buffer structure can have a higher value of Young's modulus than an encapsulant of the conformable electronic system.
