Abstract:
The invention relates to a process for the mixing and gentle transport and the transfer of powders to substrates wherein the powder particles are first charged by friction in the presence of magnetic particles and then transported by means of a fluidized bed and optionally one or more mixing rolls and then transferred and applied to a substrate by means of an electric field between a brush drum and a substrate drum carrying said substrate, characterized in that the mixing and the transport of the powder particles and the magnetic particles are carried out by means of a boiling bed.
Abstract:
A semiconductor radiation detection crystal (72) converts incident radiation or an incident particle into an electrical signal. A first substrate (74) for conveying the electrical signal to processing electronics (77) is bonded to the crystal (72) via an anisotropic conductive material (10) sandwiched therebetween. The crystal (72) can include an array of pixels (73) which are positioned in opposition with an array of conductive pads (75) formed on the first substrate (74). The anisotropic conductive material (10) forms between each pixel (73) and its corresponding conductive pad (75) an electrical path, with each electrical path isolated from other electrical paths.
Abstract:
Composite materials comprising at least 60 volume %, preferably 70 volume %, of particles of finely powdered filler material in a matrix of poly(arylene ether) polymer material are made by forming a mixture of the components, forming the required bodies therefrom, and then heating and pressing the bodies to a temperature sufficient to melt the polymer and to a pressure sufficient to disperse the melted polymer into the interstices between the filler particles. Surprisingly these polymer materials can only be effective as bonding materials when the solids content is as high as that specified, since with lower contents the resultant bodies are too friable. This is completely contrary to accepted prior art practice which considers that composites are progressively weakened as the solids content is increased, so that such content must be limited. In processes to obtain as complete a dispersion of the components as possible they are individually dispersed in a liquid dispersion medium containing the polymer together with necessary additives, each mixture being ground if required to obtain a desired particles size, the mixtures are mixed, again ground to produce thorough dispersion, are separated from the liquid dispersion medium and green articles formed from the resulting pasty mixture. The green articles are then heated and pressed as described above. Mixtures of different filler materials may be used to tailor the electrical and physical properties of the final materials. The articles preferably comprise substrates for use in electronic circuits.
Abstract:
The present invention provides a variety of interrelated methods of coating non-random and ordered arrays of particles, as well as films containing such arrays. The present invention also relates to the coated non-random and ordered arrays of particles and films prepared therefrom. The coated non-random and ordered arrays are obtained by the use of ferrofluid compositions which may be curable. The arrays and films may contain electrically-conductive particles useful in electronic applications for effecting contact between conductors.
Abstract:
A kit of components for use in constructing electrical and electronic circuits for hobby or instructional purposes is characterized by including a component (2) comprising electrically insulating permanently magnetic material (2a) having an electrically conductive layer (2b) supported thereon. The component (2) serves to locate and hold joining strips (3) and other electronic components (4) in place by magnetic attraction while completing the electrical circuit via the conductive layer (2b).
