    Pink anti-static bubble pak

    Hello, I'm wondering if anyone knows what the coating is on the pink shipping bubble wrap that gives it it's static dissapative properties? It's reacting with my pre-plated steel and I'm trying to get to the bottom of what's causing this. Thanks!

    LFM, CFM requirements on pc cards

    Heh, yes I agree. Yet, there is air moving within an enclosure I just can't see 100-200 lfm at pc slots so I guess I'm not sure how that can be recommended....I guess one just needs to ensure air movement within the box with limited/no obstruction in critical areas. cherkey

    LFM, CFM requirements on pc cards

    Thanks for reply. I thought that is was for the card but that's what I've often wondered - how to guarantee that type of airflow, especially in an atx type environment. I often think that it should just say 'we operate within these temps and xx lfm will help prevent overheating'...or...

    LFM, CFM requirements on pc cards

    Hello, Just a quick question regarding airflow specs on various cards meant for insertion into a pc: the datasheets will state something like 100 lfm required at a certain temp. Does this number refer to what should be entering the system, or what should be moving at the card itself? Thank you...

    Cantilever brackets

    Hello, I'm mounting a piece of ITE equipment, 18 x 1.5 x 10 inches, approx. 7 lbs, using a mounting bracket on either end made from .125 aluminum. The brackets are L shaped and will be mounted on the ends of the unit and then mounted to uprights thus creating the cantilever. I need to know how...

    airflow velocity

    Hello, Thanks for replies. Yes, I've used that formula before and it is what I would expect to see. Now that link, very nice little applet. It explains what I'm seeing. Thanks again to both... Chris

    airflow velocity

    Hello, Just need a refresher about what happens with air velocity as it enters an enclosure. I'm running an airflow analysis. Velocity at outlet seems correct, velocity at inlet seems correct, airflow streams seem correct. Velocity within the enclosure is almost zero. I know that the air...

    Positive or Negative cooling...

    There has been some discussion here at the office on which provides better cooling in an enclosure for electronics.&nbsp;&nbsp;I know there are factors for each but I thought I would put the question out here looking for feedback and opinions.<br><br>Thank you!<br>Chris Herkey
