Custom Program Development for Wafer Placements
“Following wafer inspection, there is a need for warehouse separation. With our conveyor belt being quite long and multiple warehouses in place, we have faced challenges in the past where incorrect stopping positions resulted in wafer destruction, causing significant difficulties for us.”
The company's wafer inspection machine is inextricably tied to the manufacturing process for both finished and NG (Not Good) wafers, requiring an extremely precise transportation and control system. Acepillar developed a technical solution to maximize overall performance, ensuring that wafers remain intact and are not broken during transportation.
Acepillar combines DI Sensor technology with EtherCAT motion control cards to assure the safe transportation and precise placement of wafers. This enables real-time information transfer and control over the stopping distance of servo motors, which meets the requirements of real-time control.
The factory is massive, and the production line is miles long. The early Motion net layout required numerous wiring, resulting in a complicated wire structure with different connections such as pulse IO signals. However, with the change, the need for extensive wiring has been decreased. A single network cable may now be used for both connections and control, making installation and maintenance easier.

The benefits of this technology extend beyond its detection accuracy to operational flexibility and scalability. Acepillar's highly flexible architecture enables for modification according on unique client needs, making it well-suited for larger and more sophisticated factories, particularly those in industries such as semiconductors or wafers that require accuracy in component and product movement. Furthermore, this technology allows for seamless connection with other production line equipment, helping to establish a more comprehensive and automated manufacturing environment.
