A tie-down strap tensioner maintains a desired strap tension on cargo when placed on a truck flatbed or sea transport. Tie-down strap tensioners are made of rubbery-type resins that remain compressive in the amount of hand applied pressure on the strap assigned to a given cargo container shape. The tie-down strap tensioner has at least three different embodiments: one is for round or radius corners such barrels, one is for square corners such as boxes, and one is for either or both round and square corners. Each tie-down strap tensioner has an upper surface and a lower surface and the lower surface has extending members that are compressive in amount of tension applied to the strap thus accommodates the shape of the cargo container selected which remains expandable to its original shape.

Tie-down strap tensioners

The packaging system includes an enclosure having an interior volume. A wafer stack, comprising plural wafers and separators in contact with the wafers, is located in the interior volume. The separators have raised bumps extending from each side. The bumps create spaces that allow air to flow therethrough. The separator film intercepts and captures airborne molecular contaminants belonging to organic and inorganic chemical families. In addition, the film is dissipative to static discharge. Furthermore, the bumps provided by the separators protect the fragile wafers from damage due to mechanical shock. The separators are also provided with a peripheral ring or embossment, which contacts the wafer edges and further protects the wafers from damage to mechanical shock. Air cushions can be provided in the wafer stack, which cushions are provided with bands to regulate the compression.

Packaging system for protection of IC wafers during fabrication, transport and storage

An inexpensive and disposable dispenser has few parts. The dispenser has a housing with a reservoir of fluid therein. The housing has a valve seat and a valve. The valve is biased in a closed position by resilient spring arms. Each spring arm has a fixed end coupled to the housing and a free end that contacts a rounded or inclined surface of the valve in a location that is offset from a centerline of movement. As the valve moves to an open position, the spring arms flex with the free ends moving apart. When the spring arms straighten and the free ends move closer to each other, the valve is moved to the closed position. The dispenser can be manipulated by a hand or by a massager. A massager imparts vibrations to the valve by way of the housing and the spring arm. The dispenser can be used to work the fluid into an object such as human skin.

A packaging system, hereinafter referred to as the Critical Packaging System, relates to critical issues that associate with sensitive articles such as IC wafers before, during and after shipment phases. The system employs a choice of two or more specialty designed containers, and any one selected design having choices of two or more methods by which to avoid, reduce and/or eliminate wafer damage from breakage, scratches and/or corrosion during shipment phases. For the purpose of maximizing product yield during packaging phases a special apparatus is used to insert wafers within containers without scratch damage. The following programs are used in packaging: (1) Quality Assurance/Certification, (2) Critical Factor Monitoring, and (3) a Recycle and Refurbish Program. These programs are specifically designed to achieve new levels of product yields, reduce product cost, and landfill impact.

Integrated circuit wafer packaging system and method

A container for integrated circuit wafers provides protection for the wafers from mechanical shock and electrical charges. The wafers are mechanically protected by top and bottom cushions and side cushions. The top and bottom cushions each have foam within a membrane or film enclosure. The enclosure has openings so as to allow gas to pass in and out. The side cushions have resilient projections that protect the edges of the wafers. The side cushions are interposed between flanges of the top and bottom cushions. The individual wafers are separated from each other by leaf separators made of film. The film for the separators and the top and bottom cushions can be the same type. The film has a first layer made of a polymer with dissipative material therein and a second layer made of a polymer without the dissipative material. The first and second layers are coupled together. The insulating layer is placed into contact with a circuit side of the wafer. The dissipative material can be carbon. The container has a grounding stud in a wall. The grounding stud contacts the film on the inside of the container and can contact a ground on the exterior of the container.

Protective system for integrated circuit (IC) wafers retained within containers designed for storage and shipment

Sensitive articles, such as IC wafers can be maintained in a contamination-free condition. A base member is provided for supporting one or more of the sensitive articles. A cover is provided for sealing engagement with a base member so as form a sealed unit. The sealed unit has an interior. The sealed unit is positioned at a storage position. A particle-free ionized gas is passed though the interior to bathe the articles supported therein with the gas at the storage position. The sealed unit is moved with the articles to an access position on associated processing equipment. The cover is removed from the base to expose the articles. The exposed articles are bathed continuously at the access position with a particle-free ionized gas. The articles are moved sequentially between the access position and a processing position on the associated processing equipment. The articles are bathed with a particle-free ionized gas during the moving steps. The cover is replaced on the base member so as to form the sealed unit and the sealed unit is returned with a processed wafer to the storage position.

Method and apparatus for maintaining sensitive articles in a

A package for storing contaminant-sensitive articles in a contaminant-free environment featuring a pair of polymeric material circular half-sections having a bottom wall and a side wall. The half sections are arranged for overlying ans sliding engagement from a spaced-apart, open position into a stop position with the side walls in a telescoping relationship to form a closed enclosure having an interior for accommodating one or more contaminant-sensitive articles, Other features include: sealing means operatively associated with at least one of the side walls for sealing the enclosure interior in the stop position, resilient clamping means or latch mechanism on the half-sections for yieldingly urging the half-sections into the stop position against the sealing means to seal the enclosure interior, means for drawing a vacuum on the enclosure, and means on the enclosure for introducing a purging ionizing gas into the sealed enclosure interior to move the half-sections out of the stop position against the clamping means to thereby relieve excessive gas pressure in the enclosure interior.

Apparatus for packaging contaminant-sensitive articles and resulting

An apparatus and method for maintaining sensitive articles such as IC wafers or the like contaminant-free including a base member having a removable cover defining a sealed unit having an interior in which a plurality of sensitive articles are supported and through which a particle-free ionizing gas from a source on a wheeled table is continuously passed, the sealed unit being movable from a storage position on the table to an access position on associated processing without interruption of the ionized gas flow and at which the cover is removed and the supported articles continuously bathed with a particle-free, ionized gas to permit the articles to be sequentially moved to a fabricating position in the processing equipment and back to the access position while being continuously bathed with a particle-free ionized gas for subsequent assembly of the cover and base member and return of the sealed unit to the storage position.

A method, system and apparatus for maintaining articles to be processed clean, having an airtight transportable container with an inlet valve for admitting ionized gas and an outlet valve for venting gas, a purger with an interface to the container inlet valve and a vacuum pick-up and ionized gas spray wand is disclosed. A purger rack for storing multiple containers is also disclosed.
