[labnetwork] MA6 lamp life

[Mark Chiappa]

Hi Youry,

I think the best routine will depend on the wattage of your system, frequency of use and of course the lamp manufacturer.  I have a 350W in our MA6 and we turn off the LPC at the end of each day as it may be several days until the next user (We have two MLA systems from Heidelberg).  When you switch the lamp off you lose ≈ 8hrs of lamp life.

The life time for our Osram lamps is stated as 650hrs, I change them after when they reach 600 hours.


1-      Off/On


2-      Change every ___ /  wait for the power to decrease by ___ % / wait for it to fail


3-      Every ___ month

 off

 650hrs





Kind regards
Mark.

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
