- Load Cassette
- Unload Cassette
- Front Door would be manually opened/closed to insert load cassette and remove.
- Filled Unload Cassette. Potentially side door would also open/close for system access.
- Laser System and head contained in enclosed top with tool removal panel for maintenance.
- click here or here or here or here for video demonstration and for manual load/unload wafer laser marking system here
- Ether net connection for remote service trouble shooting.
- Light Tower turned upright at installation.
- Getting ready for shipping fume exhaust port.
- Fan exhaust for cooling components can be vented to the floor if clean room requires.
- Link to bypass system interlocks for room interlock if desired.
- System power connection with separate system computer power connection.
The purpose below is to demonstrate an option related to cassettes and loading. The system is designed originally with industry standard cassette holders for 150mm, 200mm and 300mm wafers.
- Wafer cassettes are loaded by hand via an operator
- Interlocked door are physically closed by operator before start of wafer processing at this point if the ‘remote’ operations button is selected then production system will engage and run laser wafer system without operator intervention.
- End effector with scanner maps the wafer cassette or alternatively wafers are selected in sequence from top to bottom of the cassette without scanning (option that can be chosen on the HMI)
The following two slides present an alternative system design method where loading cassettes are installed by robot or operator no manually operated doors and required and interlocks are system verified with an option of RFDI read of cassette to determine if proper cassette is loaded prior to laser wafer operations.
The purpose of the following slides is to present examples of Human Machine Interface Optional for error messages, which can be integrated into laser automation for laser wafer marking systems with either operators running the system or complete laser automation with full lights out manufacturing, or combination of both.
All information gathered and reported is collected and used by the GEM-SECS interface and tied to your facilities production system to provide laser automation fully compliant with Semi conductor industry standard for 150, 200, and 300mm laser wafer systems.
Error messages and displayed on the main operations screen of the HMI. Error messages require acknowledgment and correction. The status light tower display matches the light tower on the system displaying system operations status. The vision system provide a view of current laser system operations on the main HMI screen.
The main operator screen of the laser automation system for laser wafer marking also provides key system operations statistics and access to other password protected operations screens.
Up to 25 text strings can be manually entered or in remote mode populated by host via GEM.
