Loading module
This module consists of thimble Z module, X/Y motion module, and blue film rotation module 4 sub-function modules. Pickup function.High temperature and normal temperature test module
This module consists of a hollow rotating platform, two 3-axis chip calibration modules on the front and back, and a 3-axis light detection module, with an ID/position recognition camera above the module, and Power on the probe to adjust the module, complete the calibration of the position and angle after feeding, and power on the chip test. The PD/collimator uses a motion axis for fast switching of functions.Camera and probe power-on module
The loading camera on the right side of the device is matched with the loading module to complete the loading recognition function of the Chip (different functional components can be matched according to the requirements of incoming materials) The camera above the high/normal temperature test module (in the middle of the device), after the chip feeding action is completed, the position calibration of the chip is completed by taking multiple pictures with the 3-axis motion module (the high temperature camera synchronously completes the ID identification of the chip).Blanking binning module
The blanking module is equipped with 4 tray placement areas, which can support 4 6-inch blue films, Or customize compatible unloading carriers according to customer needs.Parameter Type | Parameter name | Parameter index |
