An improved cooling of an electronic component loaded to a printed circuit board, wherein the PCB comprises at its upper side at least one electronic component, and at least one heat conducting member inserted into a through-hole of the PCB, wherein the HCM extends from the upper side to the lower side of the PCB and has a thermal contact to the components.

Method of manufacturing a PCB having improved cooling

Determining a jitter property of a signal with a repetitive bit sequence of a plurality of bits includes setting a sample point at a first sampling position relative to a first transition within the bit pattern, assigning a set of digital values to comparison results of the digital signal with a threshold at the set sample point for a plurality of repetitions of the bit sequence, determining a distribution value on the base of the sum of the assigned digital values, shifting the sample point by a time increment, iteratively repeating determining the distribution value until the sample point has reached a second sampling position, determining from the distribution values a distribution function over the sample points, and determining the jitter property by using the distribution function.

A noise signal generator includes a random word generator for generating a sequence of random words, each word representing an input value, a mapping unit for receiving the sequence of random words, mapping each input value to an output value of according to a probability distribution function, and providing a corresponding sequence of output values, and a digital-to-analog converter for generating a noise signal based on the output values.

Noise signal generation by mapping random words

The present invention relates to improved cooling of an electronic component loaded to a Printed Circuit Board, wherein the PCB comprises at its upper side at least one electronic component, and at least one Heat Conducting Member inserted into a through-hole of the PCB, wherein the HCM extends from the upper side to the lower side of the PCB and has a thermal contact to the component.

Printed circuit board with improved cooling of electrical component

A cooler for electric and/or electronic components with a cooling body including a first flat outer wall and a second flat outer wall at a certain distance from each other and each creating a cooling area. There are cavities between the outer walls on the inside of the cooling body, creating a cooling channel connecting an inflow with an outflow through which a liquid cooling agent can flow. The cooling channel between inflow and outflow runs completely on the inside of the cooling body, and the cooling body is made up of a first part and a second part. The first part has the first outer wall, and at least the first part has a first set of indentations on a first inner wall opposite to the first outer wall, and wherein those indentations are closed off by the second part on the wall opposite of the first outer wall when the cooling body is assembled, thus creating the cooling channel. The course of the cooling channel and/or the arrangement of the cooling section or the cooling sections in the respective application case for which the cooler was designed is adapted to the cooling needs at the first outer wall and/or the second outer wall.

Cooler for electrical and/ or electronic components, linked to present cooling needs

For determining a jitter value for a digital data signal, a jitter histogram determined for the digital data signal is substantially approximated using n normal distribution functions. The two outermost normal distribution functions are determine, and the jitter value is derived from a distance between the mean values of the two outmost distribution functions.

Jitter histogram approximation

The present invention refers to an electronic apparatus, preferably a microchip testing device, comprising at least one circuit board mounted on a cooling device. This circuit board supports at least one microchip. The circuit board supports the microchip on a side turned to the cooling device, wherein the cooling device is adapted for providing a cooling of a side of the microchip, which side is turned to the cooling device. A thermal conductor is arranged between the microchip and the cooling device for providing a thermal contact between the cooling device and the one side of the microchip turned to the cooling device. The thermal conductor comprises at least one of a group comprising: a thermally conductive knead, a plasticine, a kneadable and thermally conductive material, and a plastically deformable and thermally conductive material.

Cooling a microchip on a circuit board

The invention pertains to a plug-type connector for simultaneously connecting several coaxial cables, with said plug-type connector comprising a first plug part that is arranged on a first component and contains several first coupling elements in a first housing which are respectively connected to one of the coaxial cables, as well as a second plug part that is arranged on a second component and contains several second coupling elements in a second housing which are respectively connected to one of the coaxial cables. The two components can be separably connected to one another such that the plug parts become inserted into one another in a connecting direction. The movably supported housing contains the least one console that adjoins a first side of the corresponding component and on which a bearing journal is arranged, with said bearing journal extending through an oblong opening arranged in the corresponding component, and with the longitudinal direction of said oblong hole defining the first adjusting direction. The housing contains at least one holding-down appliance that is fixed on the bearing journal on the second side of the corresponding component which faces away from the console. The bearing journal protrudes from the oblong hole on the second side when the console adjoins the first side, namely such that the housing with its bearing journal can be displaced relative to the corresponding component in the oblong opening and said housing is supported on the corresponding component in such a way that it can also be moved in a second adjusting direction.
