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.

An electrically driven light emitting diode (LED) assembly and the method of assembling same. The assembly includes an electrically and thermally conductive heat dissipater (10) sandwiched under an electrically insulating layer (12) with circuit traces (14) disposed over the insulating layer (12) to prevent electrical conduction between the traces (14) and the heat dissipater (10). A plurality of light emitting diodes (20) have electrical leads (22) extending laterally from opposite extremities of each LED (20) to overlie the traces (14) for electrical contact with the traces (14) for powering the LEDs (20). An independent and generally U-shaped holding device (24, 26, 28, 30 and 32), as viewed in cross section, defines a base overlying the LED (20) and a pair of legs (36, 136) depending therefrom and transversely to the electrical leads (22) between the LED (20) and the heat dissipater (10). The base defines a hole (38) and the LED (20) protrudes (39) through the hole (38) to emit light. The insulating layer (12) includes a void (40) surrounding each LED (20) and the legs (36, 136) of each associated holding device (24, 26, 28, 30 and 32) and each holding device (24, 26, 28, 30 and 32) includes a tensioning portion (44 or 48) for applying a force urging the LED (20) through the void (40) and into thermal engagement with the heat dissipater (10) and the electrical leads (22) thereof into engagement with the traces (14). The tensioning portion may comprise barbs (44) on the legs (36, 136) and/or undulations (48) in the legs (36, 136).
