Laser Safety
During operation, NANYTE BEAM uses <5 mW of laser radiation to cure the UV-sensitive
photoresist. For increased safety to operator, the equipment is equipped with a laser interlock
system to prevent accidental exposure to 405 nm light. Located on the bottom side of the front
door, the magnetic door catch/interrupt can detect if the front door is closed properly. The
interlock is directly connected to the microcontroller and triggers an interrupt to disable the laser
diode output current in under 1 millisecond. Under normal operating conditions, the magnetic
interlock cannot be triggered without the use of specialized tools, such as magnetic steel plates.
The laser does not require maintenance or calibration procedures that require the enclosure to
be opened while the laser is turned on. A built-in photodiode and the camera are used for
calibration and to verify the function of the laser.
Maintenance
Before performing any maintenance, disconnect the line cord and all test cables. To maintain
protection from electric shock and fire, replacement components in mains circuits - including the
power transformer, test leads, and input jacks - must be purchased from NANYTE. Standard fuses
with applicable national safety approvals may be used if the rating and type are the same.
Other components that are not safety-related may be purchased from other suppliers as long as
they are equivalent to the original component (note that selected parts should be purchased only
through NANYTE to maintain accuracy and functionality of the product). If you are unsure about
the applicability of a replacement component, contact your local NANYTE representative.
1. To clean the equipment,
2. use a damp cloth or mild, water-based cleaner.
3. Clean the exterior of the equipment only.
4. Do not apply cleaner directly to the equipment or allow liquids to enter or spill on the
equipment.
5. Products that consist of a circuit board with no case or chassis should never require
cleaning if handled according to instructions.
6. If the board becomes contaminated and operation is affected, the board should be
returned to the factory for proper cleaning/servicing.
