Off-load system for semiconductor devices

摘要

An off-loading system comprising an array of suction tubes which are each able to pick up an associated semiconductor device from the matrix of devices and a pump which pulls air through the suction tubes to create a sufficiently low pressure within the suction tubes to allow each suction tube to pick up an associated device. In another embodiment of the invention, the off-loading system also includes a pin board which supports an array of pins configured to raise a selected array of the semiconductor devices to assist in picking up the selected array of devices from the matrix of devices. Another embodiment of the invention includes a rack that includes multiple elongated rails which form multiple channels through which the semiconductor devices travel so that they may properly enter a subsequent phase of the manufacturing process. Another aspect of the invention pertains to a method for transporting semiconductor devices from a matrix of semiconductor devices during a semiconductor assembly process using the off-loading system of the present invention. The method includes picking up a selected array of semiconductor devices individually and simultaneously from the matrix and depositing at least one of the devices of the selected array onto a handling station. In one embodiment of the method, the selected array of the semiconductor devices are raised relative to the other semiconductor devices in the matrix in order to assist in picking up the selected array of packaged devices from the matrix.
