A B-stageable dielectric composition for flow control during electronic package assembly is described. The B-stageable composition comprises a resin matrix and flow control agents. The B-stageable composition is particularly useful in laminating substrates for electronic devices and electronic components, where the flow property of the composition must be tightly controlled during the assembly.

Methods, software suites, networks, and systems of recovery point data view formation with generation of a recovery view and a coalesce policy are disclosed. In one embodiment, a network includes a virtualization module to form a data view around a recovery point, a recovery module to generate a recovery snapshot having an ability to position forward and backward from the recovery point when a rolling algorithm is applied, and an events module to generate a coalesce policy around the recovery point to reduce a storage requirement. The network may include an export module to transfer the data view to an external processing device as a virtual volume using one or more of an iSCSI and a fiber channel transport interface. The export module may automatically communicate the data view to a backup tape to provide extended data retention using a lifecycle management policy.

A method and system of recovery point data view shift through a direction-agnostic roll algorithm is disclosed. In one embodiment, a method includes forming a data view around a recovery point, and shifting the data view around the recovery point through a direction-agnostic roll algorithm that uses at least one of a roll-forward algorithm to shift the data view to a time before the recovery point and a roll-backward algorithm to shift the data view to a time before the recovery point. A data integrity may be determined to be consistent at the recover point by examining data and meta-data associated with the recovery point. The recovery point may be associated with at least one of an automatically generated event, a user definable event, and a prepackaged event. A marker data may be generated at the recovery point to enable the direction-agnostic roll algorithm to reduce a recovery time objective when an algorithm is applied.

A highly glossy thick aesthetic laminate surface layer is achieved by using pre-cured particulates of the impregnating resin preferably along with an initial binder material and abrasion resistant mineral particles. The protective overcoating may be applied in a thick layer to give gouge resistance and a deep look in the glossy laminate. The overcoated decor sheet is pressed against a mirror plate in the laminate manufacturing process, and gives a gloss meter reading well over 100. Because the impregnating resin and the pre-cured particulates have the same index of refraction, the transparency of the coating and the resultant clarity of the underlying decor sheet are excellent.

The present invention describes a mouse tail vessel injection device. The device consists of a ring situated on top of a platform, which is attached to a tourniquet, and includes a tool to place the device on and off the tail of the mouse. The ring allows access to the lumen of the tail vessel by providing the appropriate angle and width for the needle gauge. The placement tool contains 3 adjustable prongs which insert into the retainer holes attached to the tourniquet, thus allowing expansion and contraction of the tourniquet to move the device on and off the tail.

A wrist mounted toy is described wherein a pressurized canister containing a string foam compound, or other pressurizable liquid with mid to low viscosity, is attached to a vessel containing a check valve. A geared-trigger mechanism allows for the user to expel the fluid at a pressure and rate dependent on the pressure he or she places on the lever. Additionally, the actions of removing and replacing the air and fluid canisters provide the user with a more interactive experience compared to a simple load and shoot toy. Many variations can be adapted to the toy to allow for a wide range of uses. The toy allows the user to enjoy a device which resembles the Marvel character's shooter more closely and discharge the fluid to quite a distance.

Methods, software suites, and systems of generating a recovery snapshot and creating a virtual view of the recovery snapshot are disclosed. In an embodiment, a method includes generating a recovery snapshot at a predetermined interval to retain an ability to position forward and backward when a delayed roll back algorithm is applied and creating a virtual view of the recovery snapshot using an algorithm tied to an original data, a change log data, and a consistency data related to an event. The method may include redirecting an access request to the original data based on a meta-data information provided in the virtual view. The method may further include substantially retaining a timestamp data, a location of a change, and a time offset of the change as compared with the original data.

A B-stageable or pre-formed film underfill encapsulant composition that is used in the application of lead-free electronic components to substrates. The composition comprises an expandable microsphere, thermoplastic resin, thermoset resin, a latent catalyst, and a solvent. Various other additives, such as adhesion promoters, flow additives and rheology modifiers may also be added as desired. The underfill encapsulant may be dried or B-staged to provide a coating on the substrate or component that is smooth and non-tacky. In an alternative embodiment, the underfill encapsulant is a pre-formed film. In both embodiments the expandable filler material expands upon the application of higher temperatures to form a closed-cell foam structure in the desired portion of the assembly.
摘要:
A method for utilizing one or more pre-formed underfill compositions in the application of surface mount components, most commonly chip scale packages (CSP's), to substrates for use in electronic devices. The pre-formed underfill of the invention is applied directly to the top and/or sides of the CSP before the reflow process and softens during reflow to flow across the circuit/board gap. One underfill composition utilized for this method comprises a thermoplastic film system that provides a coating on the component that is smooth and non-tacky. The film may be applied selectively to parts of the CSP such that it overhangs the top of the component and upon reflow flows over the edge of the CSP to form a connection with the substrate. A second pre-applied underfill composition or solder paste may be applied as an adhesive to provide sufficient tack in order to hold the electronic assembly together during the assembly process and to serve as a flux to facilitate solder wetting.
