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.

Reticle storage system

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.

Method and apparatus for placing solder balls on a substrate

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.

Solder ball placement method

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. The invention is also directed to a solder ball dispenser for dispensing solder balls to a plate having an upper surface with an array of holes formed therein. The solder ball dispenser includes a plate support to support the plate such that the upper surface is tilted at an angle from horizontal, a ball feed device to provide solder balls to the plate, and a solder ball retainer. The solder ball retainer is movable across the upper surface of the plate for controlling a speed at which the solder balls move across the plate.

Apparatus for placing a first element at a location on a second element, there being associated with the location some known variation in the shape of the second element, the apparatus including a support member for supporting the first element while the member is translated toward the second element along a placement direction, a transporter for moving the support member or the second element along a transport direction transverse to the placement direction, a sensor for sensing the relative alignment of the support member with the known variation in shape along the transport direction, the sensor including a scanning element that is detachably engageable by the support member, and a holder for storing the scanning element when the scanning element is not in use.
