Abstract:

An apparatus for placing an array of solder balls on a substrate includes a carrier plate having an array of holes therethrough. Each hole is capable of holding a solder ball. A ball placement head having an array of pins is aligned with a desired pattern of solder balls held by the carrier plate. The array of pins push the pattern of solder balls through the holes in the carrier plate onto the substrate.

Abstract:

An apparatus for placing spheres at predetermined positions on a substrate. The apparatus includes a platform to support the substrate at a first sphere placement position in the apparatus, and a placement station disposed above the platform that places spheres at locations on the substrate. The placement station includes a first container having a chamber to contain spheres, and a first carrier tray having a substantially horizontal upper surface that forms a lower surface of the chamber. The upper surface has a first section and a second section, the second section having a plurality of holes formed therein to receive spheres. The first carrier tray is movable to position the second section between a fill position beneath the first container and a place position disposed over the first sphere placement position. The placement station is constructed and arranged to fill the plurality of holes with spheres when the second section is in the fill position, and place the spheres at the predetermined positions on the substrate when the second section is in the place position.

Abstract:

A reticle storage system includes a reticle rack having a series of lateral slots, each for storing a reticle. Access to the reticles is provided on a lateral side of the rack. The enclosure has a series of doors for providing access to the reticles in the slots. An air circulation system flows filtered air past the reticles in the rack to prevent contaminants from accumulating on the reticles. The air circulation system is capable of providing positive air pressure within the enclosure with one door open, thereby preventing contaminants from entering the enclosure through the open door.

International Classification:

B22F009/08

US Classification:

075/332000

Abstract:

An apparatus and method of forming fluxless solder balls includes forming solder balls from a supply of solder. A coating is formed on the solder balls for limiting naturally occurring oxide growth on the solder balls before significant natural oxide growth on the solder balls has occurred. The coating allows the solder balls to be soldered without using flux.

US Classification:

294 641

Abstract:

Apparatus that uses a suction engagement element to transport semiconductor wafers between processing boats and detects when suction engagement has not occurred despite the engagement element having been moved toward a wafer a distance sufficient to enable said engagement, and then adjusts the position of the engagement element relative to the object (e. g. , by backing up and trying again or by pivoting the engagement element) to facilitate the suction engagement.
