An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components.

Resilient contact structures formed and then attached to a substrate

Contact structures exhibiting resilience or compliance for a variety of electronic components are formed by bonding a free end of a wire to a substrate, configuring the wire into a wire stem having a springable shape, severing the wire stem, and overcoating the wire stem with at least one layer of a material chosen primarily for its structural (resiliency, compliance) characteristics. A variety of techniques for configuring, severing, and overcoating the wire stem are disclosed. In an exemplary embodiment, a free end of a wire stem is bonded to a contact area on a substrate, the wire stem is configured to have a springable shape, the wire stem is severed to be free-standing by an electrical discharge, and the free-standing wire stem is overcoated by plating. A variety of materials for the wire stem (which serves as a falsework) and for the overcoat (which serves as a superstructure over the falsework) are disclosed. Various techniques are described for mounting the contact structures to a variety of electronic components (e.g., semiconductor wafers and dies, semiconductor packages, interposers, interconnect substrates, etc.), and various process sequences are described. The resilient contact structures described herein are ideal for making a "temporary" (probe) connections to an electronic component such as a semiconductor die, for burn-in and functional testing. The self-same resilient contact structures can be used for subsequent permanent mounting of the electronic component, such as by soldering to a printed circuit board (PCB). An irregular topography can be created on or imparted to the tip of the contact structure to enhance its ability to interconnect resiliently with another electronic component. Among the numerous advantages of the present invention is the great facility with which the tips of a plurality of contact structures can be made to be coplanar with one another. Other techniques and embodiments, such as wherein the falsework wirestem protrudes beyond an end of the superstructure, or is melted down, and wherein multiple free-standing resilient contact structures can be fabricated from loops, are described.

Electrical conductors formed from mixtures of metal powders and metallo-organic decomposition compounds

The present invention relates to a thick film formed of a mixture of metal powders and metallo-organic decomposition (MOD) compounds in an organic liquid vehicle and a process for advantageously applying them to a substrate by silk screening or other printing technology. The mixtures preferably contain metal flake with a ratio of the maximum dimension to the minimum dimension of between 5 and 50. The vehicle may include a colloidal metal powder with a diameter of about 10 to about 40 nanometers. The concentration of the colloidal metal in the suspension can range from about 10 to about 50% by weight. The MOD compound begins to decompose at a temperature of approximately about 200 DEG C. to promote consolidation of the metal constituents and bonding to the substrate which is complete at temperatures less than 450 DEG C. in a time less than six minutes. The mixtures can be applied by silk screening, stencilling, gravure or lithography to a polymer-based circuit board substrate for producing rigid and flexible printed wiring boards in a single operation with negligible generation of hazardous wastes. The same mixtures can be used in place of solder to assemble circuits by bonding electrical components to conductors as well as to make the conductors themselves.
