Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] 1. Establishment of the classification operation area model of the production line

[0043] Production line modeling is based on the principle of enterprise hierarchical management, and establishes a hierarchical operation area model by constructing the basic elements of the model. The basic elements of the model include equipment, workstations, and operating areas. Among them, there is a corresponding relationship between equipment and workstations. On the semiconductor packaging line, a piece of equipment must land on a station, and the relationship between the equipment and the station is one-to-one; a lowermost working area contains multiple processing stations, and the working area and the working station have a one-to-many relationship ; The upper-level operation processing area contains multiple lower-level operation areas, and...

Abstract

The invention discloses a semiconductor packaging line-oriented scheduling method based on an operation area. The method comprises the following steps: firstly, creating a production line stage operation area model, realizing multistage management of equipment on the semiconductor packaging line according to areas, meeting the requirement of frequent change of a correlation relation between the equipment on the packaging line, and distributing the operation area model to scheduling personnel for binding the scheduling personnel with the area model managed, controlled and scheduled by the scheduling personnel; secondly, performing scheduling, namely selecting a scheduling operation area by the scheduling personnel, screening LOT sets for scheduling in the scheduling area, selecting equipment in the scheduling area through control on a plurality of production scheduling rules bound with processes in the scheduling process, and calculating processing time of the LOTs selected for scheduling, project start time, project completion time and the processing equipment distributed to the LOTs according to information of number of chips in the LOTs and information of the selected equipment so as to finish the scheduling process.

Description

technical field [0001] The invention belongs to the field of production scheduling, and mainly relates to a semiconductor packaging line LOT multi-rule scheduling method based on an operation area. Background technique [0002] The semiconductor packaging line has a large number of equipment in the chip loading and bonding process. In the actual production of semiconductor packaging enterprises, it is divided into multi-level areas for management, and there are a large number of parallel machines in each area. Before production scheduling, it is necessary to establish an effective means to describe and manage the complex production organization structure and huge amount of equipment of the semiconductor packaging line. [0003] Since the semiconductor packaging line is produced for customer orders, the equipment on the production line is constantly recombined according to the changes in customer order requirements, and the relationship between production equipment is changed...
