How many software features should a company buy from a software vendor? The more integrated the software and functionality purchased, the easier and more convenient IT, procurement, projects, management and support will be. For this reason, semiconductor manufacturing companies were the first to use integrated manufacturing management information systems (MES), and in recent years, most companies have also adopted ERP systems for accounting, planning, and administrative office processing.
However, these decades have shown manufacturers that there is always a limit to what a single supplier or single solution can provide to the depth of applications required to successfully run semiconductor manufacturing. Many semiconductor companies find themselves in a similar situation: outdated MESs have been in place for years, and ERP systems cannot keep up with manufacturing management needs. So, the question arises: "What kind of solution will meet our needs?"
Let's take a look at what a traditional MES looks like
What people say: "It's reliable, stable, but also very old. The biggest complaint about it is that it doesn't work with a mouse because it's a character-based interface. It still requires a lot of paper for most applications other than WIP."
Problems with paper documents:
1. If the customer wants to know the information about a certain batch, he must go to the warehouse to find it manually;
2. Inability to perform analysis on different batches using the same equipment, operator or time;
3. Inability to perform quality event analysis;
4. Older batches of paper documents are likely to be damaged due to various reasons, such as rodent infestation;
5. Unable to link with device to reduce manual setting.
Let's look at the ERP system
After purchasing an ERP system, a company decided to apply all engineering processes except wafer manufacturing to the shop floor operation module of the new ERP system. However, when the company tried out the ERP shop floor control system on a job shop (the old MES application had been running before), they found that the ERP system was working very badly due to problems with the interface between the old MES and the new ERP system . Because, it only provides some of the control and quality functions, such as work in process tracking, and these functions are only used for financial recording of the data. As a result, the company had to supplement the paper-based ERP module.
Integrated software
A company after using traditional MES as well as ERP systems and modern MES systems, finally they found that an integrated software solution made more sense and changed direction and looked for a solution provider that could provide all these functions in one place .
The company approached four providers for tenders:
1) The original ERP provider: they did not bid because they knew their system could not meet the requirements;
2) Another ERP provider: They can provide all the functions needed, but they are fragmented modules that are neither combined in an integrated product nor for semiconductor wafer fabrication and subsequent needs. So the problem of integration is highlighted again;
3) Old-fashioned MES software providers applied before: There is no powerful user interface (UI) and excellent flexibility to adjust and change the system as business and product needs change;
4) The winning MES provider: After considering flexibility, user interface, and features specific to semiconductor manufacturing, the company chose a modern MES solution that satisfied them.
Semiconductor companies use modern MES to manage all aspects of production, including dispatch management, statistical process control (SPC), nonconforming product management, dashboards, and maintenance management, in addition to WIP tracking and control. Each part may have some small plugins, but the core system is integrated and the whole system is platformized. Starting a product evaluation with this insight in mind will shorten your search and reduce the frustration of finding suppliers in the future.
The biggest feature of the smart factory is that the production system can be reconfigured to change the attributes and parameters of the relevant production system. The supply of resources throughout the supply chain must be visible and fully transparent in terms of availability. To achieve intelligent production, transparency must first be achieved. Efficiency MES system plays a linking role in the entire production process of the enterprise. It is between ERP and the bottom automation of the workshop. It is an indispensable informatization method for enterprises to achieve lean manufacturing and flexible production.
Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
