Sometimes true point-to-point wiring—without terminal strips—with very short connections, is still used at very high radio frequencies (in the gigahertz range) to minimise stray capacitance and inductance; the capacitance between a circuit-board trace and some other conductor, and the inductance of a short track, become significant or ...
Board-to-board (BTB) connectors are used to connect printed circuit boards (PCB), electronic components that contain a conductive pattern printed on the surface of the insulating base in an accurate and repeatable manner. Each terminal on a BTB connector is connected to a PCB. A BTB connector includes housing and a specific number of terminals.
Additional to the traditional screw contacts the electrical connection between the module and other parts of the power electronic system can also be achieved by pin contacts (soldered onto a PCB), press-fit contacts pressed into PCB vias, spring contacts that inherently press on contact areas of a PCB or by pure pressure contact where corrosion-proof surface areas are directly pressed together ...
In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. [1] The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point.
PCB mount connectors soldered to a printed circuit board, providing a point for cable or wire attachment. [6]: 56 (e.g. pin headers, screw terminals, board-to-board connectors) Splice or butt connectors (primarily insulation displacement connectors) that permanently join two lengths of wire or cable
In the 1990s the use of multilayer surface boards became more frequent. As a result, size was further minimized and both flexible and rigid PCBs were incorporated in different devices. In 1995 PCB manufacturers began using microvia technology to produce High-Density Interconnect (HDI) PCBs. [14]
