UV lamps

WACOM UV lamps are used in exposure equipments for lithography process on semiconductor devices,FPDs,PWBs and more.

Operating precautions


  • Do not look directly at the operating lamp.Highly luminous and ultraviolet rays from the lamp damage human eyes.
  • Do not expose skin directly to the operating lamp. Doing so may cause inflammation of the skin.
  • Keep away from the lamp during and also a short while after operation. Otherwise,high heat cause burns.
  • Keep paper, cloth and other flammables away from the lamp during and also a short while after operation. Otherwise,high heat causes fires.
  • Be sure that the anode and the cathode of the lamp are correctly positioned as indicated. The lamp becomes unusable if mispositioned. 
  • Be sure to use specified equipment and a specified power supply. Wrong application may have the lamp burst.Turn off the power supply before installing or removing the lamp and also before maintenance the equipment. Otherwise, a worker may get a shock. 


  • The lamp is glass products. Protect the lamp from strong shock, scratching, twisting, and bending.
  • Change the lamp on or before the expiration date of the average life.Overused lamp may possibly burst due to deterioration of quartz glass.
  • Be sure to use correct electric current, voltage, and cooling air as indicated. Wrong application may have the lamp burst and reduce the lifetime.

UV lamps for Semiconductor production


These lamps are for use in noncritical patterning for semiconductor production.

With low light deterioration, they are excellent for stabilizing throughput.


UV lamps for FPD production


These lamps are for use in fine patterning for flat panel display production.We have developed supersized UV lamp for making large-sized FPDs.


UV lamps for PWB production


These lamps are for use in fine patterning for printed wiring board production.

Many manufacturers use these high-quality lamps as genuine products.


Precautions in Handling

  • The lamp emits powerful UV radiation and pressure within the lamp rises when in use. Only operate the lamp in an appropriate lamp housing.
  • Do not look directly into the lamp without eyes protection when it is lit. Strong UV radiation may damage the eyes.
  • Cleaning the lamp with alcohol soaked soft and clean cloth before operation is always recommended.Fingerprints and other grime on the lamp surface may interfere with normal operation.
  • Thermal expansion can result in damage if the caps at both ends of the lamp are tightened. Allow 2-3 mm of movement on one side of the lamp when attaching it.
  • UV lamp specification is for the vertical point light. 
  • Be sure the cap labeled "UP" is always facing upward. In addition, check the polarity when fixing the lamp. Operating with reversed polarity may result in damage or other problems.
  • Be sure the lamp and lamp housing terminals are not oxidized or discolored before fixing to prevent problems caused by a loose connection.
  • Be sure the persons or company responsible for disposing of used lamps are licensed for disposing of industrial waste. The lamps contain high-pressure gases, mercury and other materials that may cause injury or environmental damage.
