Abstract

The invention discloses an X-ray electronic device detection system which comprises a case, a two-dimensional moving worktable arranged in the case, an X-axis stepping motor and a Y-axis stepping motor which drive the two-dimensional moving worktable to move, an X-ray generator arranged below the two-dimensional moving worktable, an X-ray image intensifier arranged above the two-dimensional moving worktable, wherein the two-dimensional moving worktable mainly consists of a bearing sliding plate, a movable table rack, a longitudinal sliding rail, a longitudinal belt, a transverse sliding rail, a transverse belt and a fixing frame; a movable table rack moving and limiting device mainly consists of two metal proximity sensors, a metal sheet and a controller. With the adoption of a bearing sliding plate moving and limiting device and the movable table rack moving and limiting device, movement of the worktable is limited, so that the machine is safe and reliable in operation, and the service lives of the belts and the stepping motors are prolonged.

Description

technical field [0001] The invention relates to an X-ray detection system, in particular to an X-ray detection system for detecting semiconductor devices. Background technique [0002] For example, in the production of high-performance, high-complexity, high-quality PCB (printed circuit board), in addition to ensuring excellent raw materials, advanced production technology, equipment and advanced management mode, it must also have complete technical quality Guarantee system and advanced testing equipment. At present, the design and processing level of printed circuit boards has reached 0.15-0.12mm (line width and spacing), and the number of layers has reached 46 layers (Fuji Company) or even more. It can be said that the high technology and high complexity of PCB have reached A very high level, but in the production process, how to improve the product quality of the intermediate process, how to reduce the scrap rate, and how to improve the PCB quality are the goals that all...
