Method of creating an enhanced BGA attachment in a low-temperature co-fired ceramic (LTCC) substrate
Patent number: 6408511Abstract: A method for providing an enhanced ball grid array attachment in low-temperature co-fired ceramic (LTCC) substrate is provided. A termination cup is formed in a substrate. The termination cup has a bottom formed by a termination pad over a via in a first tape layer and side walls formed by termination sides formed over side walls of a via in a second tape layer. A diffusion layer is formed over the termination cup. The diffusion layer helps to reduce the oxidation of the termination cup and to provide greater mechanical attachment strength.

Patent number: 6394330Abstract: A method of converting a web of indefinite length into a plurality of web portions by slitting the web at a transverse point prior to processing the web portions into a plurality of use supply forms (such as rolls), wherein the plurality of web portions are separated by a two-stage process. A first stage of the process is a partial separation operation that almost entirely separates the web portions, but leaves the web portions connected, such as by a slitting operation that leaves a series of connected zones. The second stage includes the complete separation, such as by breaking of the connected zones. The complete separation of the web portions preferably occurs near the station at which the use supply forms are created, such as a winding station. Thus, the web portions, after substantial separation at the first stage can be handled (for example, guided and tensioned) as if the plurality of web portions were a full width web.Type: GrantFiled: August 13, 1998Date of Patent: May 28, 2002Assignee: 3M Innovative Properties CompanyInventor: Byron M.

Patent number: 6353998Abstract: A fixture for aligning the leads of SMT components with the corresponding pads of the printed circuit board, which is to receive such components, before soldering the leads to the pads. The fixture includes clamps for applying forces directly to the leads of the SMT components, alone or in conjunction with the clamping forces which are traditionally applied to the body of the component, the applied forces sufficient to seat the leads on the corresponding pads. In a preferred embodiment, the forces are applied by providing the fixture with a series of rocker-type clamps, each having an edge for engaging the several leads associated with a particular SMT component to be joined to the printed circuit board. The clamp is preferably constructed of a non-wettable material so that the edge of the clamp will not be wet by the molten solder during the soldering procedure, and the edge is preferably thin so that the clamping surface in contact with a particular lead is minimized.Type: GrantFiled: February 1, 2000Date of Patent: March 12, 2002Assignee: International Business Machines CorporationInventors: Wilton L.
