  • Patent number: 8496113
    Abstract: An insert for a carrier board of a test handler is disclosed. In a first aspect, the latch block applying to the insert is detachably coupled to the insert body. The latch block can be reused, and thus this reduces wastage of resources and eliminates the insert replacement fee. In a second aspect, the insert pocket having hooks is detachably coupled to the insert body. The insert body can be reused. The latch unit is installed to the insert pocket, so that the damaged latch unit can be easily replaced. The insert forms a plurality of holes in the bottom of the loading part thereof, to expose the leads of the semiconductor devices through the holes downwardly. Thus, the insert can load semiconductor devices regardless of the dimensions of the semiconductor devices.

  • Patent number: 8376431
    Abstract: A pick-and-place module for test handlers is disclosed that includes a main body and a kit. The main body forms vacuum paths therein and the kit also forms vacuum passages therein. The kit is detachably mounted to the main body in a hook coupling manner. The pick-and-place module can be applied to all customer trays having different loading capabilities when only the kit of the pick-and-place module needs to be replaced, so there is no need to manufacture the entire pick-and-place module and this reduces manufacturing costs. The pick-and-place module can reduce the amount of resources to be replaced and reduce the replacement time since the kit can be easily removed from the main body of the pick-and-place module in a hook manner.

  • Patent number: 8013620
    Abstract: When a test handler loads semiconductor devices of user trays onto a test tray, the test handler adjusts a front/rear pitch or a right/left pitch between the semiconductor devices, adjusts the right/left pitch or the front/rear pitch, and loads the semiconductor devices. The test handler can sequentially adjust individually the front/rear pitch and the right/left pitch between the semiconductor devices, thereby reducing the apparatus weight and the loading time.
