摘要:
The present invention relates generally to a plating buss design and method for minimizing short circuit problems in PCB panel singulation. More particularly, the invention encompasses a serpentine plating buss which increases the PCB singulation process window thereby minimizing short circuit problems due to indexing errors caused by occasional manufacturing and equipment alignment problems. The serpentine plating buss design therefore increases board yield.

Stacked microfeature devices and associated methods of manufacture are disclosed. A package in accordance with one embodiment includes first and second microfeature devices having corresponding first and second bond pad surfaces that face toward each other. First bond pads can be positioned at least proximate to the first bond pad surface and second bond pads can be positioned at least proximate to the second bond pad surface. A package connection site can provide electrical communication between the first microfeature device and components external to the package. A wirebond can be coupled between at least one of the first bond pads and the package connection site, and an electrically conductive link can be coupled between the first microfeature device and at least one of the second bond pads of the second microfeature device. Accordingly, the first microfeature device can form a portion of an electrical link to the second microfeature device.
摘要:
A method of encapsulating an article having first and second surfaces, includes positioning the article on a carrier such that at least a portion of the first surface contacts the carrier. A portion of the carrier carrying the article is then positioned within a mold and a seal is formed between the mold and the carrier. The mold is then filled with an encapsulating material to form a seal between the article and the carrier.

The present invention relates to a method of encapsulating a plurality of chip and board pre-assemblies. Each pre-assembly has first and second surfaces. The method includes positioning a first mold half in a sealing relationship with each first surface of the pre-assemblies and positioning a second mold half adjacent each second surface of the pre-assemblies. The first mold half is filled first thereby forcing each second surface of the pre-assemblies into a sealing engagement with the second mold half. The second molding section is then filled, to result in an asymmetrically overmolded chip and board assembly.

A foundation for supporting poles, particularly electrical power cable support poles, is formed by boring a hole only slightly larger than the pole base onto the earth a desired depth. A reinforcing structure is lowered into the hole. The reinforcing structure usually rests on the bottom of the hole and extends above the earth surface a number of feet. The hole is then filled with concrete, usually up to the earth surface, and allowed to cure. A lowermost or base section of the pole is then lowered into position about an exposed upper portion of the reinforcing structure. Concrete is placed into the interior of the pole section about the reinforcing structure until it is covered. After the concrete cures, any remaining pole sections may be installed onto the base section.

The process is an improvement over the chlorination of EDC in a boiling bed. The reactants, chlorine and dichloroethane (either 1,1- or 1,2-) are mixed in the vapor phase and passed over a molecular sieve which serves as a catalyst to produce 1,1,2-trichloroethane.

Methods for fabricating conductive structures on and/or in interposing devices and microfeature devices that are formed using such methods are disclosed herein. In one embodiment, a method for fabricating interposer devices having substrates includes forming a plurality of conductive sections on a first substrate in a first pattern. The method continues by forming a plurality of conductive sections on a second substrate in a second pattern. The method further includes constructing a plurality of conductive lines in a common third pattern on both the first substrate and the second substrate. The conductive lines can be formed on the first and second substrates either before or after forming the first pattern of conductive sections on the first substrate and/or forming the second pattern of conductive sections on the second substrate.
