In reference to your evaluation of a future purchase of a exposure unit consider this: The design of the cooling systems of certain exposure units is such that very little air flow reaches the lower lamp area, specifically during higher production modes. The result can be lamp life inconsistencies and / or premature mechanical failures due to excessive heat build up. You will need to either choose a unit that does not have this type of design, or manufacture an additional air flow channel to aid in the cooling for the lower lamp. For your application this may not present a problem due to short exposures, but..... something to think about. *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
