Patent EP-0082271-A2 (EP)
Inventor: AINSLIE NORMAN GEORGE
IPC: B23K35/00
Filed: 1982-10-26
Abstract: Brazing of the pins and mounting flanges to electronic chip carrying substrates requires brazing materials which remain solid at the temperatures used to remove and replace chips. The flanges and pins are brazed with an initially eutectic Au:Sn brazing alloys which is modified during brazing by addition of copper to promote formation of the higher melting point phase of the alloy. A Group VIII metal is also added during brazing to draw Sn out of the melt by gettering, further to promote formation of the phase of the alloy and to thicken the braze material.As shown a multilayer substrate 10 has a molybdenum pad 11 coated with a protective layer of nickel 12. A relatively thick copper layer 13 (0.0002 - 0.0025 cms) is coated with a very thin (up to 1.25 µm) layer of nickel 14 to serve as tin gettering metal A braze fillet 15 of Au80:Sn20 is positioned on the layer 14 and surrounds the nickel plating 17 on Kovar pin 19. When the joint is brazed at a nominal temperature of 395°C the copper 13 and nickel 14 react with the braze fillet material and on cooling, the brazed joint material has a raized melting point.

Abstract: A tape 1 comprising a fibrous reinforcement, a layer of adhesive which can be activated by heat and a strip of metallic foil is heated by the passage of an electric current through the foil so as to activate the adhesive and is then pressed into contact with two pieces of fabric to be joined. The electric current passes along two conductors 4 from a power unit 3 supplied by a source 2 and is caused to flow for a length of time which is controlled in accordance with the average temperature reached by the foil as computed by a micro-processor 8 from the variation of its electrical resistance derived from the potential drop across its ends for a predetermined current flow, tapped off by conductors 5. When the average temperature approaches a value corresponding to full activation of the adhesive, an indication is provided to the operator by an indicator 9 and then, after an interval of time sufficient to allow the operator to press the tape against the joint between the two pieces of fabric, as measured by a timer 10, the current is automatically switched off by the microprocessor 8.

Abstract: Disclosed is an apparatus useful in controlling the operation of ovens of the type typically associated with baking food products. Broadly, the apparatus permits the linear display of heat input to one or more zones of an oven responsive to gas flow. Heat input is indicated by fluid levels in manometers having their legs dimensioned to permit linear display of heat input despite the variance of gas flow with the square of the pressure. The manometers are positioned next to an adjustable scale which accommodates combustible gases of varying heat contents. The adjustable scale is preferably marked for the preferred heat input profile across the various zones of the oven to facilitate control of optimum heat input to the oven as a whole. Also disclosed are similar display devices for exhaust gases.

Abstract: In an electro-optic line printer of the type having a bit addressable linear modulator for modulating a sheet-like beam of light in response to pixel bits to expose the printer recording medium in line-by-line fashion, interference between the beam upper and lower sidebands is suppressed by selective polarisation. In one form, the beam is vertically polarized and a halfwave plate, disposed so that the axis thereof is at 45° to the Fourier transform plane, is inserted into the path of one of the sidebands to change the polarization of the one sideband from vertical to non- interferring horizontal. In a second embodiment, a halfwave plate is inserted into the path of each sideband, the axes of the plates being such as to form a 45° angle therebetween whereby the sidebands are polarized at an angle of 90° to one another avoiding interference therebetween.

Abstract: A method and apparatus for converting radiant energy levels to digital data wherein an image sensor is provided having at least one row of sensor elements each including a light sensitive capacitor and an access switch and which changes state and produces a corresponding binary output signal when a predetermined charge threshold is exceeded by the capacitor whose charge is a function of intensity and period of an illumination. The row of elements is first calibrated by illuminating same with a reference light source and sensing at a first frequency (F) such that approximately one half of the elements change state and counting the digital output signals corresponding to the changes of state to obtain a first number (B). Thereafter, the row is illuminated with an unknown light source which has a lower radiant energy level than that of the reference light source and senses at a frequency F/2. The digital output signals corresponding to the changes of state are counted to obtain a second number (A). The numbers A and B are compared to produce a digital "1" signal when A > B and a digital "0" when A < B corresponding to digital data bit N 1 . The sensing and comparing are repeated for each successive bit N 2 , N 3 ...N k  of a K bits of digital data at successive sensing frequencies in accordance with

Abstract: An adhesive layer (3) and an insulating layer (4) of ceramic material are consecutively applied by plasma jet spraying to a surface of a metal substrate (2) roughened by sandblasting. Then a solderable layer (5) is applied to the insulating layer (4) and at least one integrated circuit, in particular a power semiconductor (1) is then soldered to it. The insulating layer (4) makes possible an insulated structure of the integrated circuit under these circumstances. The thickness of the insulating layer (4) is at the same time specified only on the basis of the desired dielectric strength, i.e. the insulating layer (4) is applied thinly enough to ensure a good removal of the heat loss produced in the integrated circuit into the metal substrate (2). The adhesive layer (3) is intended to prevent the insulating layer (4) peeling off under thermal alternating loads. A material whose coefficient of thermal expansion is between that of the metal substrate (2) and that of the ceramic substrate of the insulating layer (4) is therefore used for the insulating layer (3). Preferably, the adhesive layer (3) is made up of a plurality of sublayers in a way which results in a gradual transition in the coefficient of thermal expansion. <IMAGE>
