    Medical devices regulation regarding types of flux

    Thanks for the link @marce! But I don't think this really applies for us, its only for R&D use... Thanks for all the help, Trout

    Medical devices regulation regarding types of flux

    Thanks, this helps a lot! One question though - what do you mean that medical devices don't need RoHS? The EU requires every electronic device to be RoHS compliant, and the US has started this in all states beginning from 2014 (if i'm not mistaken)... Thanks, Trout

    Medical devices regulation regarding types of flux

    Hi all, I have a small regulation question regarding production of medical devices: Is there a definition somewhere of what types of flux can and cannot be used in medical devices? I know that the solder wire should always be RoHS, but this is a more general regulation and not medical devices...

    Problem with printing to PDF from OrCad

    I seems like it isn't working yet... Could you please explain the whole process: How do I convert the schematic to postscript? Do I import the file to Gimp and than save it as PDF? Am I missing something? Thanks, Trout

    Generating and Conrolling a Frequency Sweep

    Hi, I have a small problem, and I'm hoping somebody here can help me... I need to find the resonance frequency of an LC circuit: I have a half FET bridge to driver the circuit and I need to sweep around the theoretical resonance frequency to find the effective frequency. After I find the...

    Thanks! For some reason our teacher found it really hard to explain this to us, and basically dodged the question every time :)
