  2. Lead (electronics) - Wikipedia

    en.wikipedia.org/wiki/Lead_(electronics)

    A lead wire is a metal wire connected from the electric pole of an electronics part or an electronic component. The lead wire is a coated copper wire, a tinned copper wire or another electrically conductive wire used to connect two locations electrically.

  3. Leading and lagging current - Wikipedia

    en.wikipedia.org/wiki/Leading_and_Lagging_Current

    Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...

  4. Lead frame - Wikipedia

    en.wikipedia.org/wiki/Lead_frame

    Lead frame for a QFP package, before encapsulation DIP 16 pin Lead frame, after encapsulation and before cutting/separation. The lead frame consists of a central die pad, where the die is placed, surrounded by leads, metal conductors leading away from the die to the outside world. The end of each lead closest to the die ends in a bond pad.

  5. Flat no-leads package - Wikipedia

    en.wikipedia.org/wiki/Flat_no-leads_package

    Flat no-lead is a near chip scale plastic encapsulated package made with a planar copper lead frame substrate. Perimeter lands on the package bottom provide electrical connections to the PCB. [1] Flat no-lead packages usually, but not always, include an exposed thermally conductive pad to improve heat transfer out of the IC (into the PCB).

    In beam-lead technology, the metallized pads that would be used for wire bonding connections in a conventional chip are thickened and extended to allow external connections to the circuit. Assemblies using "bare" chips have additional packaging or filling with epoxy to protect the devices from moisture.

    en.wikipedia.org/wiki/Dual_in-line_package

    For example, for a 14-lead DIP, with the notch at the top, the left leads are numbered from 1 to 7 (top to bottom) and the right row of leads are numbered 8 to 14 (bottom to top). Leads are skipped on some DIP devices (e.g. segmented LED displays , relays, or devices that replace leads with a heat sink fin).

    “Consumer electronics often rely on components sourced from numerous countries, so tariffs on specific parts can raise overall retail prices,” says Rodriguez.

  9. Whisker (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Whisker_(metallurgy)

    The European Restriction of Hazardous Substances Directive (RoHS), which took effect on July 1, 2006, restricted the use of lead in various types of electronic and electrical equipment. This has driven the use of lead-free alloys with a focus on preventing whisker formation (see § Mitigation and elimination). Others have focused on the ...
