Abstract

The invention provides an appearance inspection apparatus for a semiconductor assembly, and an optical path structure thereof. A base of the optical path structure is at least provided with a pickingand placing mechanism and an appearance inspection zone, wherein the picking and placing mechanism is provided with a suction head; the suction head comprises, from top to bottom, a buckling and clamping sleeve member, an annular sleeve and a suction nozzle; the annular sleeve has a conical surface which is increasing smaller from top to bottom; and the appearance inspection zone at least comprises two sets of strip light source, and the two sets of strip light source are apart from each other and arranged face to face. Thus, when the suction head is moved to a place located between the two sets of strip light source, light emitted by the two sets of strip light source is downwardly reflected by the conical surface of the annular sleeve, so uniform backlight is provided for inspection.

Description

technical field [0001] The invention belongs to the technical field of semiconductor component appearance inspection equipment, and in particular relates to a semiconductor component appearance inspection equipment and an optical path structure that can improve the backlight intensity in inspection operations and increase the accuracy of appearance inspection. Background technique [0002] With the development of science and technology, the size of semiconductor components is getting smaller and smaller to meet the needs of consumers who require products to be thin, light and short. After the semiconductor components are produced, they will be placed on the carrier tray, and then moved to the relevant inspection machine by the transfer mechanism for a series of inspection operations. As the size of the semiconductor components becomes smaller, relative derivative problems must be overcome in the inspection operations. [0003] figure 1 It is a structural schematic diagram o...
