  • Publication number: 20050090040
    Abstract: The electrical contacts, such as ball grid array (BGA) solder balls, of an integrated circuit (IC) are coupled to printed circuit board (PCB) bonding pads that include vias. According to an embodiment of an electronic assembly, the vias are formed off-center, so as to inhibit bridging between adjacent solder balls during a solder reflow operation by minimizing the effect of solder ball ballooning resulting from outgassing of a thermally expansive substance, such as a volatile organic compound (VOC) from the via channels. The bonding pads are separated into two groups, each having vias offset in a different direction, so that asymmetric surface tension forces in the molten solder during a solder reflow operation do not cause the IC to slide to one side. A substrate, an electronic assembly, an electronic system, and fabrication methods are also described.

  • Patent number: 6622905
    Abstract: An apparatus, comprising a substrate having a surface, comprising one or more solder pads, each having a center and connected to a via, each via having a center; positioned relative to the surface such that at least one of the one or more solder pad centers is offset from the connecting via center and an area of the at least one of the one or more solder pads overlaps an area of the connecting via.

  • Publication number: 20020084105
    Abstract: The electrical contacts of an integrated circuit are coupled to printed circuit board (PCB) bonding pads that include vias. A method for fabricating an electronic assembly utilizes at least one operation in which a thermally expansive substance, such as a volatile organic compound (VOC), is applied to the PCB. Some of the VOC goes into the via channels. The electrical contacts of a surface mount technology component such as a ball grid array (BGA) solder ball component are affixed to the bonding pads using a reflow soldering technique. According to one embodiment, the vias are formed off-center, so as to inhibit bridging between adjacent solder balls during a solder reflow operation by minimizing the effect of solder ball ballooning resulting from outgassing of the VOC from the via channels. A substrate and an electronic system are also described.
