Transistor

By the application of voltage or current this device has the function of a controllable electrical resistor, so it can be used as a switch, for example. Transistors displaced electron tubes as signal amplifiers on all technical sections, except in broadcast. There are two important groups of transistors, bipolar-transistors and field effect-transistors, who differ in the form of control.

IC

An IC (integrated circuit) is a group of electronic circuits, that are stored in only one electronic device.

Flip-Chip-Mounting

The Flip-Chip-Mounting is an operation in manufacturing engineering of electronic devices to contact semiconductor chips via contact hills, called bumps. In the process, the device is mounted directly, without connecting wire contacts down to the substrate.

Hybrid Technology

The hybrid technology is a connection method to produce electronic circuits with both integrated and discrete devices.
A discrete device is in the electrical engineering a separate device that is arranged in one package. In contrast in integrated circuits are several devices.

Reflow-Soldering

Reflow-Soldering is a process in which a solder paste is used to temporarily attach one or several electric components to their contact pads to permanently connecting it, by melting the past with controlled heat.

SMD

A surface mounted device (SMD) is an electronic device, that is mounted laminary on a circuit board. There are no connecting wires but conductor pads, which are connected with contacts on the circuit board.
