HI,



We leave the lamp on all the time, 350w lamp we run at 24 mw/cm2 and change the lamp when it drops below 20 mw/cm2,

HI Everyone,



I have 3 quick questions about your policy for changing the UV-lamp on the MA6 (Karl Suss) mask aligners.

1. do you turn off the UV - power supply during nights and weekends? or just leave it on?

2. do you change the UV lamp on a regular basis (after 1 month or so)? or you monitor it's power and have a lower limit before you decide to change it? or you just wait for it to fail and then change it?

3. how often do you change the lamp?



Thanks and Happy July 4th

Youry
