Abstract:
A contact tail for an electronic component compatible with surface mount manufacturing techniques. The contact tail is stamped, providing a relatively low manufacturing cost and high precision. High precision in the contact tails in turn provides more reliable solder joints across an array of contact tails in an electronic component. Further, the contact tail may be shaped to reduce the propensity for solder to wick from the attachment area during a reflow operation. Reducing the propensity of solder to wick reduces the chance that solder will interfere with the operation of the electronic component. Additionally, reducing the propensity for solder to wick allows pads to which the contact tail is attached to be positioned over vias, thereby increasing the density with which contacts may be attached to a substrate. The reliability with which electronic assemblies incorporating components using the contact tail is also increased when the contact tail is used in self-centering arrays.
Abstract:
A device includes a circuit element, a housing for the circuit element and a terminal for coupling the circuit element to an electrical circuit. The terminal includes an engagement portion and a sleeve portion. The engagement portion is configured to engage a base for the electrical circuit. The sleeve portion couples the engagement portion to the circuit element. The housing encloses the sleeve portion.
Abstract:
A contact tail for an electronic component useful for attachment of components using conductive adhesive, which may be lead (Pb) - free. The contact tail is stamped, providing a relatively low manufacturing cost and high precision. The contact tail has a distal portion with a large surface area per unit length. The distal portion shapes conductive adhesive into a joint, holding the adhesive adjacent the lead for a more secure joint. Additionally, the distal portion holds adhesive to the contact tail before a joint is formed, facilitating the use of an adhesive transfer process to dispense adhesive. The further aid in the transfer of adhesive, the contact tail may be formed with concave portions, which increase the volume of adhesive adhering to the contact tail. By adhering an increased but controlled amount of adhesive to the contact tail, arrays of contact tails may be simply and reliably attached to printed circuit boards and other substrates.
Abstract:
A surface mounting discharge tube, comprise of a cylindrical ceramic envelope sealed at its two ends by side surfaces of electrodes, designed to be directly soldered on to a mounting board, where the electrodes at the two ends are rectangular, project outward radially at the ends of the ceramic envelope and are provided at peripheral edges at the side surfaces of the electrodes with soldering use tapers or step differences, whereby positional deviation at the time of soldering is suppressed and sufficient PCT properties are secured.
Abstract:
A method of fixing reflowable elements on electrical contacts. The method includes providing a strip having a number of electrical contacts, each contact including a contact body and a tail portion extending away from the contact body. The tail portions of the contacts are then disposed adjacent an elongate reflowable member. The elongate reflowable member is pushed onto the tail portions of the plurality of contacts. Subsequently, the elongate reflowable member is cut into a plurality of separate reflowable elements, each reflowable element corresponding to one of the tail portions. The electrical contacts with the reflowable element attached thereto are separated from the strip.

Abstract:
A method for repairing a lighting system comprises identifying a fault location; disposing over or under the substrate at the fault location a patch comprising (i) a patch substrate, (ii) two conductive traces disposed on the patch substrate, and (iii) a replacement light-emitting element electrically coupled to the two conductive traces of the patch; and electrically connecting the replacement light-emitting element across the fault location by electrically connecting each of the conductive traces of the patch to one of the conductive traces defining the fault location.
