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.

Disclosed is a construction bracket supporting temporary construction structures such as safety railings and scaffolding which are composed of construction members such as steel or wooden beams. The bracket has a support plate and a substantially hollow column member extending upwardly from the support plate. The column member is provided with at least one aperture adapted to receive a tightening member for securing the construction members to the column member.

The present invention is concerned with providing a support for temporary lighting for use with scaffolding systems. The support assembly comprises of two main components and the required fastening systems to affix lighting fixtures and mast light fixtures embodied in two configurations. The support consists of a thin walled pipe with a tube half clamp welded to one end and a thin walled tee welded to the opposite end. The clamp and tee are orientated to provide the support with a precise mounting position. A second thin walled pipe is positioned concentrically through the tee to create framework that has an angled appearance. The second pipe is maintained annular and concentric to the first pipe by means of two washer type collars welded above and below the tee that constrains both pipes to each other. A small space between the collar and tee provides the second pipe with unconstrained rotational movement. Lanyards incorporated in the support are fixed directly to the scaffold for job site safety concerns. Another aspect of the invention is the tube half clamp, which can provide quick assembly and infinite positional placement on a horizontal or vertical pipe member of a scaffolding system.
