1.1 A standard procedure for the three-omega method is proposed for measuring the thermal conductivity ofa thin, electrically insulating film, on a substrate having a thermal conductivity significantly greater than thethermal conductivity of the film. This method is applicable to a film on a silicon substrate with the followingcharacteristics:a) the film is electrically insulating;b) the film has a thermal conductivity that is less than one tenth the thermal conductivity of silicon;c) the film is uniform in thickness and the thickness lies in the range 0,25 μm to 1 μm;d) the maximum dimensions of the film are limited by the sizes of the preparation and measurementapparatus;e) the minimum dimensions of the film are limited by the minimum size of the circuit element that can beplaced on the film surface.NOTE A specimen approximately 15 mm by 25 mm is of an appropriate size although specimens as small as10 mm × 10 mm are usable.1.2 The method is directly applicable to films of silicon dioxide on silicon wafer substrates.1.3 The method may be applicable to insulating films on other high-thermal conductivity substrates providedthat the parameters of the substrate material are substituted for the parameters of silicon used in this methodand the associated computer program.1.4 The method is applicable to measurements near room temperature.
This European Standard specifies a measurement procedure to determine the thermal transmittance of glazing with flat and parallel surfaces. Structured surfaces, e.g. patterned glass, may be considered to be flat...
This standard defines terms used in the plastics industry, including terms and definitions appearing in plastics standards (of ISO/TC 61), and general terms and definitions of polymer science used in all aspects of plastics technology.
This European Standard specifies a measurement procedure to determine the thermal transmittance ofglazing with flat and parallel surfaces. For the purpose of this Standard, structured surfaces may beconsidered to be flat..This European Standard applies to multiple glazing with outer panes which are not transparent to far infraredradiation (in the wavelength range 5μm to 50μm), which is the case for soda lime silicate glass products,borosilicate glass and glass ceramics. Internal elements can be far infrared transparent.The procedure specified in this European Standard determines the U value (thermal transmittance) in thecentral area of glazing. The edge effects due to the thermal bridge through the spacer of an insulating glassunit or through the window frame are not included. Energy transfer due to solar radiation is also excluded.The procedure specified in this European Standard should be considered only when the thermal transmittanceof the glazing cannot be calculated in accordance with EN 673.The determination of the thermal transmittance is performed for conditions which correspond to the averagesituation for glazing in practice.
This International Standard defines the terminology used in the field of printed circuitboards and printed circuit board assembly products.
This part of IEC 61189 provides a catalogue of test methods representing methodologies andprocedures that can be applied to test materials used for manufacturing interconnectionstructures (printed boards) and assemblies.
This part of IEC 62258 has been developed to facilitate the production, supply and use ofsemiconductor die products, including? wafers,? singulated bare die,? die and wafers with attached connection structures,? minimally or partially encapsulated die and wafers.The standard defines the minimum requirements for the data that are needed to describe suchdie products and is intended as an aid to the design of and procurement for assembliesincorporating die products. It covers the requirements for data, including? product identity? product data? die mechanical information? test, quality, assembly and reliability information? handling, shipping and storage informationIt covers the specific requirements for the data that are needed to describe the geometricalproperties of die, their physical properties and the means of connection necessary for their usein the development and manufacture of products. It also contains, in the annexes, a vocabularyand list of common acronyms.
