摘要:
A testing probe structure for wafer level testing semiconductor IC packaged devices under test (DUT). The structure includes a substrate, through substrate vias, a bump array formed on a first surface of the substrate for engaging a probe card, and at least one probing unit on a second surface of the substrate. The probing unit includes a conductive probe pad formed on one surface of the substrate and at least one microbump interconnected to the pad. The pads are electrically coupled to the bump array through the vias. Some embodiments include a plurality of microbumps associated with the pad which are configured to engage a mating array of microbumps on the DUT. In some embodiments, the DUT may be probed by applying test signals from a probe card through the bump and microbump arrays without direct probing of the DUT microbumps.

A drawing device of the present invention includes a first driving element, a bolt, a plurality of second driving elements, and a plurality of clipping rods. The first driving element drives the second driving elements to rotate simultaneously, so that the clipping rods are able to be rotated and operated. Also, a hook portion of each clipping rod is able to hook to a bottom of objects to be drawn out, and the bolt is disposed on a threaded hole of the first driving element and abuts against the objects to be drawn out. At the same time, the clipping rods are moved outward.

Methods and apparatus of performing floorplanning and routing for function blocks within a die and among multiple die are disclosed. Multiple die together with function blocks within each die may be represented by a flexible hierarchical (FH) tree. An initial floorplan for multiple die may be generated and hot spots between die or among function blocks within a die may be identified. Spacer blocks may be inserted between die, and block inflation may be performed, to remove hot spots. More perturbation of the block positions can be performed on the FH tree to rearrange the blocks and die. After the multiple die floorplanning, a plurality of micro bumps may be mapped to a plurality of pins of blocks of the plurality of die, placement and routing may be performed for the plurality of blocks within each die and connections for the plurality of dies.

The present disclosure relates to a method of routing probe pads to micro-bumps of an interposer. An interposer is provided having target micro-bumps and probe pads. The probe pads are initially unassigned. Target micro-bump locations and probe pad locations are obtained. Possible route assignments from the probe pads to the target micro-bumps are obtained. Costs are developed for the possible route assignments at least partially according to the target micro-bump locations and the probe pad locations. Final assignments are selected from the possible assignments according to the costs.

According to the present invention, the oil filter replacement device has a number of pins for clamping an oil filter, and the pins are extended eccentrically from corresponding secondary gear members. The secondary gear members are engaged to spin simultaneously by a main gear member. As such, the pins could be adjusted to fit on oil filters of various sizes. Additionally, each pin is rotatable and has at least a flat face. As the pins rolls along the circumference of the oil filter, their flat faces are turned to interface the flat faces around the oil filter. As such, the oil filter is tightly and reliably clamped by the oil filter replacement device, thereby preventing the problem of uneven exertion of force and deforming the oil filter.

An oil filter canister adapter of the present invention mainly includes a base, a rotatable plate, three rotatable members, and three holders. The rotatable plate and the rotatable members are respectively disposed on the base. The rotatable members contact with the rotatable plate respectively, so that the rotatable plate can rotate and drive the rotatable members to rotate. The holders are detachably disposed on the rotatable members respectively. Distances between any two adjacent holders are consistent in value. The distances between the holders are adjustable when the rotatable members rotate.Therefore, the holders can be detached from the rotatable members. Volume of the adapter is minimized for storage. As such, cost of transportation or storage of the adapter can be well controlled.
