High-repeatability position identification method and device for laser diode chip

Abstract

The invention discloses a high-repeatability position identification method for a laser diode chip. The method specifically comprises the following steps of 1, basic positioning operation, 2, advancedpositioning operation and 3, the basic operation of a device, and relates to the technical field of chips. According to the high-repeatability position identification method and device for the laserdiode chip, the device can be manually adjusted by a worker, a manual screw can drive a position display block to move to an accurate position, and meanwhile, a certain angle is formed in the surfaceof a limiting block, so that the chip can conveniently fall onto the surface of the limiting block in time when a working telescopic rod extends, and can automatically fall onto the surface of the limiting block along with the limiting block; and through the arrangement of a position marking device, the whole device can drive a positioning head to move to a related accurate position by moving a horizontal top plate leftwards and rightwards, and a clamping plate in the device can be pushed by a reset spring to be tightly fixed to the surface of the horizontal top plate, so that the operation accuracy of the device is improved.

Description

technical field [0001] The invention relates to the field of chip technology, in particular to a method and device for high-repeatability position recognition of a laser diode chip. Background technique [0002] A chip refers to an integrated circuit that manufactures a circuit on the surface of a semiconductor chip, also known as a thin film integrated circuit. Another kind of thick film integrated circuit is a miniaturized circuit composed of independent semiconductor devices and passive components integrated into a substrate or circuit board. Integrated circuits have two main advantages over discrete transistors: cost and performance. The low cost is due to the fact that the chip has all its components printed as a unit by photolithography, rather than making only one transistor at a time. The high performance is due to the fast switching of components and lower energy consumption because the components are small and close to each other. In 2006, the chip area ranged f...
