Patent number: 8390126Abstract: A module (20) can include a first substrate (12) comprised of a first material, at least a second substrate (22) comprised of at least a second material, selectively applied solder (14) of a first composition residing between the first substrate and at least the second substrate, and selectively applied solder (16) of at least a second composition residing between the first substrate and at least the second substrate. Preferably, no crack will exist in the module as a result of a reflow process of the solder due to the CTE mismatch between the first and second substrates. The different selectively applied solder compositions can have different melting points and can be solder balls, solder paste, solder preform or any other known form of solder.Type: GrantFiled: October 3, 2003Date of Patent: March 5, 2013Assignee: Motorola Mobility LLCInventors: Vahid Goudarzi, Juli A.

Patent number: 7773224Abstract: A system (200) and method (800) for determining whether a sample object (203) has a color that is within a predetermined range is provided. The system (200) includes a light source (201) capable of projecting lights having different light wavelength spectrum upon the sample object (203). A controller (222) causes the light source (201) to project a first light wavelength spectrum upon the sample object (203), then another, then another, and so forth. While each light is projecting upon the object, a monochromatic image capture device (202) captures an image having luminous intensity information. The luminous intensity information, or a subset thereof selected by an image selection tool (232) is then compared to the statistical range, which is derived from a plurality of images taken of a reference object (403).Type: GrantFiled: September 28, 2007Date of Patent: August 10, 2010Assignee: Motorola, Inc.Inventors: Fan He, Shumin Cheng, Michael Frenzer, Bin Jiang, Vahid Goudarzi

Patent number: 7413110Abstract: A method (80) of reducing stress between substrates of differing materials includes the steps of applying (82) solder (16) on a first substrate (14), reflowing (84) the solder on the first substrate to form a cladded substrate (30), applying (85) a medium such as flux or solder on a second substrate (42) having a substantially different coefficient of thermal expansion than the first substrate, placing (86) the cladded substrate on the second substrate, and reflowing (88) the cladded substrate and the second substrate such that thermal stress caused by the substantially different coefficient of thermal expansion between the first and second substrates is limited to when a temperature approximately reaches below a solidus temperature of the solder on the first substrate.Type: GrantFiled: February 16, 2005Date of Patent: August 19, 2008Assignee: Motorola, Inc.Inventors: Vahid Goudarzi, Julio A.

Patent number: 7167375Abstract: A populated printed wiring board (PWB) (100) and method of manufacturing the populated PWB are taught. The populated PWB is manufactured by fabricating a PWB (102, 402) with exposed copper pads (302), coating the copper pads with an organic solderability preservative (OSP) (404), depositing a solder paste that includes lead-free solder on the OSP covered copper pads (406), placing components (408) and heating the PWB above a liquidous temperature of the lead-free solder in an air atmosphere (410). The process allows very close spacing of components and component leads while forming reliable solder joints to components that are mechanically stressed and components that have non-negligible planarity or coplanarity tolerances.Type: GrantFiled: January 16, 2004Date of Patent: January 23, 2007Assignee: Motorola, Inc.Inventor: Vahid Goudarzi

Publication number: 20060182939Abstract: A method (50) of forming a solder mask on a portion of a module (40) using for example LTCC technology includes the steps of forming (52) a multilayered ceramic substrate (20) with exposed metallization forming solder pads (28 or 31), masking (54 or 56) the solder pads by placing an additional ceramic layer (22 or 32) on the substrate that at least covers at least a portion of periphery of the solder pad using the LTCC process. The method can further include applying (58 or 60) solder (36) to a portion of the solder pad not covered by the solder mask (22) and placing a printed circuit board (34) having a different coefficient of thermal expansion than the multilayer ceramic substrate on the multilayer ceramic substrate to form the module before reflowing. The module can then be reflowed to form the module without cracks.Type: ApplicationFiled: February 11, 2005Publication date: August 17, 2006Applicant: Motorola, Inc.Inventors: Vahid Goudarzi, Edwin Bradley, Kinzy Jones, Gustavo Leizerovich
