Have been established in assembly industry, panel industry, the semiconductor industry and the LED industry many MES system ciMes import performance information computer, the product manager Wen Guang Zeng revealed that during 2012, on the mainland won about 7 to 8 LED manufacturing plant favored, including the largest, Sanan optoelectronics Anhui factory, factory in Xiamen and to set up by the country star optoelectronic 100% investment of country star semiconductor factory in Foshan, all can be described as one of the index cases.

Accumulated a lot of successful cases, has summed up the number of the LEDMES system on the introduction of the common problems. First is in the part of system suitability, the difference of the planning system and the actual production operation; the second is part of an operating system for, often find user operation too complicated, or no closer to the actual field operations; the third is the demand can not be implemented; the fourth is Zhao due to the change of demand on the yield, production management, personnel management transaction caused by; the fifth is led core of a large number of production, deal with the lack of experience; the sixth is the lack of personnel training; finally, ERP vendors do not have led industry knowledge, leading to difficulties in integrating.

Under this premise, Wenguang hence according to EPI (EPI / epitaxy) and chip (chip / grain), LEDPackage, led factory automation facets, sequentially proposed MES system implementation advice.

The EPI manufacturing processes, mainly covering the substrate (blank wafer production management, epitaxial quality data collection and control, fast measurement / verify production management, extension judgment operation, the extension of storage management, production and management of basic statements, and ERP integration work.

As for system on chip was introduced, including wafer production pick the extension of production management, PSS process production management (for graphical substrate manufacturing process, in order to ascension window), wafer front process production management, wafer pumping detecting, wafer road production management, wafer manufacturing full measurement / warehousing sorting / visual inspection (AOI) key process production management, wafer, shipment pick the goods management, ERP integration operation, production and management of basic statements. And in the LEDPackage, the focus is on the production of pipe picking operation, production parameters management (tuning parameters management... ), material management and traceability (silver glue, phosphor, Golden Globe), quality management, judgment, etc. operations (electrical measurement classification), storage management operations, packaging operations management (packaging pick the goods), implement the cost and accuracy (including personnel and equipment working hours and materials costs), and production and management of basic statements.

Pick up a single, containing indium and, SECS/SECSII PLC/OPC Wen Guang Zeng said that harness the, such factory automation solutions need to consider the focus, which includes the machine architecture (including control box, the EPI automation feasibility (the key machines containing MOCVD and EL) and chip automation feasibility (the key machines grinding, measuring, sorting counter and AOI), MES and ERP integration; the MES / ERP integration, especially must pay attention to the BOM, industry and trade, and other related materials, as well as piecewise work order, extension and the wafer, chip shipments to pick the goods system, the other is worth mentioning, ERP system for LED business process characteristics, but also need to support product changes.

About LEDMES benefits of adoption of, it is helpful to reduce the production time, improve the order on time of exchange rate, reduce WIP (work in process), defect reduction and yield enhancement, material and product traceability (through product production experience), precision production cost, providing real-time manufacturing information, and asked the customer response time and improve customer service satisfaction; sums up theory is implement automation integration, to reduce human errors, in order to improve the productivity and yield rate, and finally to strengthen the competitiveness of enterprises.
