What’s VQFP Package?   VQFP is Very Thin Quad Flat Pack, or Very Thin Quad Flat No-Lead Package (QFP).

What’s VSOP Package?   Very Small Outline Package (VSOP) is one of several smaller versions of the SOIC package, having a compressed body and a tightened pitch for its gull wing leads. Another smaller version of the SOIC is the …

What’s TSSOP?   The Thin Shrink Small Outline Package, or TSSOP, is a rectangular surface mount plastic package with gull-wing leads. It has a smaller body and smaller lead pitch than the standard SOIC package. It is also smaller and …

In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as …

A flat package of rectangular cavities (egg carton) for storing surface mount devices. Also called matrix trays.

Wide Area Network (WAN) is a long-distance communications network that covers a wide geographic area, spanning regions, countries, or even the world. However, in terms of the application of communication protocols and concepts, it may be best to view WANs …

What’s Watt?   The watt (symbol: W) is a unit of power or radiant flux. In the International System of Units (SI), it is defined as a derived unit of (in SI base units) 1Kg·m2s-3 or, equivalently, 1 joule per …

Wave is a ripple or undulation. All electromagnetic radiation, including radio signals, light rays, x-rays, and cosmic rays, as well as sound, behave like rippling waves in the ocean.   What’s Wave Impedance?   Wave Impedance defines the impedance experienced …

Wave Soldering is a PCB assembly technique, which is the most common mass soldering technique for through-hole PCBs. A board is passed over a wave of molten solder wetting the various component leads to be joined.

What’s Wavelength?   In physical, the Wavelength is the spatial period of a periodic wave – the distance over which the wave’s shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such …
