  • Pick-and-place module for test handler
    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.
