Ability of a solder joint to resist a force applied parallel to the printed circuit board.

The property of a fluid (usually solder paste) whereby the viscosity (that is, the resistance to flow) reduces temporarily as the fluid is subjected to an increased shear force, (for example by a squeegee during the print process.

What Is Sheet Resistance in PCB?   In printed circuit board (PCB), Sheet Resistance, also called Sheet Resistivity, or Surface Resistivity is an important property to quantity the ability for charge to travel along the uniform thin films, like carbon, …

What Is PCB Shield?   PCB Shield is the mechanical approach of adopting conductive, magnetic or both materials to prevent EMI in the electronic device. Mechanical shields are closed, metal cans, like brass, nickel silver and stainless steel, which connected …

Short circuit. An abnormal connection of relatively low resistance between two points of a circuit. The result is excess (often damaging) current between these points. Such a connection is considered to have occurred in a printed wiring CAD database or …

In signal processing, a Signal is a function that conveys information about a phenomenon. In electronics and telecommunications, it refers to any time varying voltage, current, or electromagnetic wave that carries information. It may also be defined as an observable …

Layer of a board, in which traces can be placed. For a two-sided board two signal layers are available – the Top and the Bottom layers.

Signal Loss is the loss of strength of a signal as it propagates over a medium. Generally, in PCB design and manufacturing, the term refers to loss of signal strength in guided media, such as impedance controlled lines. Signal Loss = …

A Silicon atom has 14 electrons around the nucleus, and of these, there are 4 valence electrons on the outermost orbital. When this is made into a single crystal, it can be used as a material for semiconductor products. When …

What Is a Silicon Transistor?   A Silicon Transistor is a semiconductor made with a silicon base. It is used in a wide variety of electronic devices, such as televisions and phones, to alter the flow of electrical current. Silicon …
