A method for prefabricating pore defects by controlling a SLM process, including performing laser scanning on a specified metal melt layer (LY) according to a first scan path (P) and a second scan path. The first scan path (P) and the second scan path (P) have a path overlap zone (A), the path overlap zone (A) has a predetermined width, and laser energy input superimposed in the path overlap zone (A) is controlled to reach a predetermined energy value, whereby keyholes are formed at a plurality of positions in a lengthwise direction of the path overlap zone (A), the specified metal melt layer (LY) is taken as a defect layer, and the keyholes in the path overlap zone (A) is taken as pore defects.

Method for prefabricating air hole defect by means of controlled SLM process

A debug apparatus for debugging a chip under test with a plurality of pins is provided. The debug apparatus includes a processor for controlling the chip under test via a bridge device. The processor provides graphical data to indicate pin states of the chip under test when the chip under test is controlled by the processor.
