Selected Applications From Semiconductor/Display Industry
Special tools are needed to inhibit collisions between objects in OHT equipment operation. This objective can be realized with the aid of laser scanners.
• OHT: An automated transport system that moves on the overhead track.
Stable and reliable detection of PCB boards in PCB magazine loaders regardless of protrusions, holes, or intrusions on the boards is a vital matter which can be realized with aid of BJP series photoelectric sensors.
Solid state relay terminal blocks can be applied for stable load switching within SMT machinery.
A considerable matter in the production and transport process of displays is to figure out the presence and placement of glass substrates in LCD, and OLED cassettes. Mapping sensors help us with this.
Semiconductor and display heat regulators need to be carefully controlled for temperature. So, Power controllers are used for exactly this purpose.
A key safety issue when working with packaging machines is that the doors of these machines remain completely closed during operation and can only be opened after the operation is completed. Safety door lock switches help us realize this issue.
One of the things that should be done with machines in an emergency is to stop the machine at the earliest opportunity. Emergency stop button switches help us in this serious job.
The location on transport trays on PCB loader machines can be detected via Photomicro sensors.
Graphic panels set up on semiconductor boat loaders are suitable solutions for monitoring and controlling wafer carrying processes.
The Location and movement of wafer cassettes in semiconductor transfer machines can be reliably controlled via closed loop stepper motor systems.
Robot type extension cables can be applied in conjunction with displacement sensors In the process of robot position controlling with no risk of breaking.
How can we detect wafers in significantly high-temperature environments?
Fiber optic units seem to be the right solution.
Safety non-contact door switches aid us in monitoring opening & closing of multiple doors in manufacturing lines.
The pressure of vacuum ejectors for the absorption in the course of the pick and place process must be monitored. The PSS series aids us in gaining this objective.
Vision sensors aid us in detecting the presence and absence of components for defects throughout semiconductor transfer lines.
We can be aware of the presence and absence of semiconductor wafer carriers (FOUP) through Push button type photomicro sensors.
It is necessary to detect the suction status of semiconductor components in the process of semiconductor production. Dual display pressure sensors help us in this regard.
Moving and checking the X-Y axis location of trays in the course of manufacturing semiconductor components are vital phases that can be reliably performed using stepper motors and Photomicro sensors.
The level of cleaning fluid in semiconductor cleaning equipment can be highly reliably detected using photoelectric liquid level sensors.
The motion rail shafts in dispenser machines can be reliably controlled using 5-phase micro step motor drivers.
Designers have been looking for a reliable way for controlling the rotation of reels in SMD reel counters. Finally, they came up with the idea of Shaft type 5-phase stepper motors.
Several instruments including 5-phase stepper motors and motor drivers, Pressure sensors, logic panels, interface terminal blocks, and photomicro sensors have proved to be reliably applied in the inspection process of LCDs of mobile electronic devices.
