<p class="MsoNormal"> The most often referenced material is from SEMI standards. Semistandards.org<o:p></o:p></p>
<p class="MsoNormal">Whatever criteria you adopt, please note that it is of the utmost importance to ensure consistency. If temperature and RH vary, it will introduce unwanted variables in sensitive and complex processes. Another important point is to keep
the RH relatively high (48%) to reduce ESD. If the RH and temperature fluctuate, you will encounter variation in your photo speed.<o:p></o:p></p>
<p class="MsoNormal">Hope this helps.<o:p></o:p></p>
