    Avoiding freezing in water tanks

    The few that I have seen were just mounted underground. Fixes the heat and insulation problem. But if yours is already installed above it doesn't help much

    First Job out of school

    Thanks to all who have replied. I completely agree that I am not truly done with classes. I know that if I stop learning, especially in this field, I might as well retire because I'm done. I only meant that I am done with college level, generic classes. I actually look forward to classes...

    First Job out of school

    I have probed to see what the chances of becoming a regular employee where I am currently an intern. They cannot hire in our department right now and have no idea of when that will change. They have already extended my internship past its original completion date to keep me around. I think...

    First Job out of school

    The designer would be an engineering position but it would start out with very limited responsibility. I thought this sounded like a step backwards but thought it might be a good way to shadow experienced MEs. I live in a city where Mechanical Engineers are not highly sought after. The...

    First Job out of school

    I'm done with class forever in about a month from now. I will have a BS in ME. I have a company that tracked me down through a current employee. They would like me to come interview for a drafter position they have which would potentially lead to a designer job. I'm currently working as an...

    Finding Case Temp

    I'm evaluating a product made by another company for our use. We expect this product is thermally challanged and we need to measure temps and compare to the datasheets to see how close to the limit we are. As I said I'm and intern with almost no experience with this kind of testing. So far I...

    Finding Case Temp

    Wouldn't there be some difference because I'm not actually in direct contact with the case though?

    Finding Case Temp

    Sorry if this is a dumb question. I'm new and an Intern. I have some thermocouples mounted into the base of some heat sinks to get temp readings while running a stress test in my chamber. How can I find out what the case temp is of the chips? Do I just need to worry about the thermal...

    PCB Light Pipes?

    It will be for fairly high volume production so we will probably just have to tool up and do it. They wanted me to find an off the shelf option if possible but I doubt it.

    PCB Light Pipes?

    I have been assigned to find a light pipe solution for one of our new products. The problem I'm having is finding an off the shelf light pipe for our application. It must fit aroung a socket that measures roughly 1.5" deep by .5" tall. I have looked at KingBright and Bivari. Does anyone have...

    CNC Millers

    At school we use exclusively Miltronics. They have worked very very well for us but I'm not sure if they were purcased because they're less expensive or because they are just as good. We have not had any problems with them in the 2 years i was there and that's with students hammering...i mean...

    Ice in my Halt chamber

    I'm trying to convince them to connect the nitrogen gas purge system since our tank and chamber are set up for it. This morning we put new foam in all the ports and it seemed to help quite a bit but we still have a little snow and fog. The drier is not deccicant type. Its the type with a...

    How to reverse engineer gaskets?

    I would try contacting a gasket manufacturer. If they think you may be a future customer they might give you an insight on what you are looking for. Or you could describe the application some and ask for help here. Most likely there will be someone with the experience to point you in a direction.

    Ice in my Halt chamber

    The first thing i suspected was the compressor air entering the chamber to run the drivers on the vibe table. I checked and it has a working water remover. The low pressure thing would cause air to enter anywhere it could though and we've been relatively humid here lately. We are not...

    Ice in my Halt chamber

    Hi all, We have a QualMark Halt & Hass chamber here at my work. I can't seem to figure out how all the moisture is getting into it. When we take it down below zero C it ices up bad. We don't have the nitrogen purge hooked up but the other guy figures that after a while the LN2 used to cool the...
