Electronic Glossary

A small amount of current that flows across a dielectric area between two adjacent conductors.

What is a LED?   A LED (light-emitting diode) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of …

Legend, also called Silkscreen, a format of printed letters or symbols on the PCB, such as part numbers and product number, reference designator or logos.

The Low-Profile Fine Pitch Ball Grid Array (LFBGA, or LFPBGA) is a smaller version of the ball grid array (BGA) package. It is basically an FBGA package that has a package height ranging from 1.2 mm and 1.7 mm. It is …

What’s LGA Package?   The Land Grid Array (LGA) is a package that uses metal pads for external electrical connection instead of leads (as in the pin grid array -PGA) or solder balls (as in the ball grid array -BGA). …

Life Cycle Assessment (LCA) is a systematic technique for identifying and evaluating the potential environmental benefits and impacts (use of resources; human health; ecological consequences) associated with a product or function throughout its entire life from extraction of raw materials …

A thin conductive area on a PCB surface or internal layer usually composed of lands (to which component leads are connected) and paths (traces). Same as Conductor.

What is Line Regulation?   Line Regulation is the ability of a power supply to maintain a constant output voltage (Vo) despite changes to the input voltage (Vi), with the output current drawn from the power supply remaining constant.   …

Linear is the relationship between input and output (I/O) in which the output varies in direct proportion to the input.

The transfer of a pattern or image from one medium to another, as from a mask to a wafer.
