摘要： A method of fabricating a BGA (Ball Grid Array) IC package of the type having an encapsulating body is proposed, which allows the BGA IC package to be manufactured without having to use conventional organic substrate and encapsulating-body mold having cavity, so that the manufacture process can be more cost-effective to carry out than the prior art. The proposed method is characterized in the use of a copper piece which is selectively removed to form an encapsulating-body cavity for the forming of an encapsulating body therein. The proposed method requires no use of mold with cavity for the forming of the encapsulating body, allowing the same mold to be used for the fabrication of various BGA IC packages of different sizes. Moreover, the proposed method allows fan-in design as well as fan-out design, thus allowing the number of I/O ports to be increased while making the overall package configuration compact in size, and also allows the implantation of the electrically-conductive balls to be easier to carry out and more precisely controlled than the prior art, making the ball implantation more assured in quality than the prior art. Therefore, the proposed method is more advantageous and cost-effective to use than the prior art.

摘要： A ball grid array semiconductor package is proposed, wherein at least a chip is mounted on a substrate, and signal pads on the chip are electrically connected to signal fingers on the substrate by bonding wires. A power plate and a ground plate are each attached at two ends thereof respectively to predetermined positions on the chip and substrate, without interfering with the bonding wires. No power ring or ground ring is necessarily formed on the substrate, thereby reducing restriction on trace routability of the substrate. Further, with no provision of power wires or ground wires, short circuit of the bonding wires is less likely to occur, and thus production yield is enhanced. In addition, the power plate and ground plate provide shielding effect for protecting the chip against external electric-magnetic interference, and are partly in direct contact with the atmosphere for improving heat dissipating efficiency of the semiconductor package.

摘要： A built-in module for an inverter and having tension control with integrated tension and velocity closed loops, where required tension feedbacks can be obtained by internal calculations of the inverter or feedback signals of a tension sensor. The tension control module is applied to provide a tension control for a winding mechanism which is operated by driving at least one motor. The tension control module firstly builds a tension control to provide a balanced tension to the winding mechanism. Afterward, the tension control module builds a velocity control to provide an accelerated or decelerated adjustment for the winding mechanism. Accordingly, the winding mechanism can stably maintain a tension-balanced operation.

The heat dissipating structure includes a flat portion, and a plurality of support portions formed at edge corners of the flat portion for supporting the flat portion above a chip mounted on a substrate. The support portions are mounted at predetermined area on the substrate without interfering with arrangement of the chip and bonding wires that electrically connect the chip to the substrate. The support portions are arranged to form a space embraced by adjacent supports and the flat portion, so as to allow the bonding wires to pass through the space to reach area on the substrate outside coverage of the heat dissipating structure; besides, passive components or other electronic components can be mounted on the substrate at area within or outside the coverage of the heat dissipating structure, thereby improving flexibility in component arrangement in the semiconductor package.

摘要翻译： 提供具有散热结构的半导体封装。 散热结构包括平坦部分和形成在平坦部分的边缘角部处的多个支撑部分，用于将平坦部分支撑在安装在基板上的芯片上。 支撑部分安装在基板上的预定区域上，而不干扰将芯片与基板电连接的芯片和接合线的布置。 支撑部分被布置成形成由相邻支撑件和平坦部分包围的空间，以便使接合线通过该空间以到达散热结构外部覆盖层上的基板上的区域; 此外，无源部件或其他电子部件可以在散热结构的覆盖范围内或外部的区域处安装在基板上，从而提高半导体封装中的部件布置的灵活性。
