<p>1299541 Beam lead integrated circuits; assembing components WESTERN ELECTRIC CO Inc 15 Jan 1970 [21 Jan 1969 (2) 29 April 1969] 1998/70 Headings H1K and H1R A method of assembling an electrical component, e.g. a beam lead integrated circuit, in a predetermined position relative to external circuitry comprises providing co-operating ferromagnetic means in or affixed to the electrical component and the external circuitry such that the magnetic force exerted by the co-operating magnetic means serves to align the component in the predetermined position. The ferromagnetic means associated with the component may be in the leads or on the body of the component and may be in the form of a coating applied by, for example, sputtering, evaporating or plating or may be deposited during production of the component as an embedded layer. The ferromagnetic means associated with the external circuitry may be integral therewith or in the form of a coating. Alternatively, an electromagnet may be affixed to the circuitry in order to position the component and then removed. This method may be used to form temporary or permanent contacts between the component and the circuitry; if permanent contacts are required, the contacts are permanently bonded by, for example, laser welding. Magnetic means may be used to guide the component to its correct position by causing virtual movement of an electromagnetically generated field.</p> |
