Abstract
Apparatus and methods are provided for handling packaged integrated circuits (IC's), particularly for inserting packaged IC's in and removing packaged IC's from low-insertion-force (LIF) sockets. The apparatus includes a precisor having a chip precisor feature for receiving an IC package and a socket precisor feature for receiving a socket in a predetermined alignment relative to the chip precisor feature. One or more releasable chip retainers are provided, such as a vacuum nozzle for pulling the packaged IC into a seated position within the chip precisor feature and a pair of gripper fingers for holding the packaged IC within the chip precisor feature during extraction from a LIF socket. A method of inserting a packaged IC into a socket comprises centering a precisor relative to an expected location of a packaged integrated circuit, moving the precisor to a predetermined height relative to the expected location, applying vacuum to a nozzle so that a packaged IC is pulled into a chip precising feature of the precisor, centering the precisor relative to a socket, and moving the precisor into a seated position on the socket in which the packaged IC is aligned with and inserted into the socket. A method of removing a packaged IC from a socket comprises positioning a precisor relative to a socket containing a packaged IC, moving the precisor into a seated position on the socket in which the packaged IC is seated in a chip precising feature of the precisor, closing a gripper to retain the packaged IC within the chip precising feature, and moving the precisor away from the seated position while retaining the packaged IC within the chip precising feature.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
