    High Speed Laser Hole Drilling

    We're trying to determine what laser technology is required for the high speed pierecing of thin metals. Our application calls for 0.004" hole in both 6061 and CRS of thicknesses varying from 0.015-0.025. From several RFQs and respective quotes, we've learned that many if not most laser...

    PCB routing (clock lines and termination) help

    Well I thought I did a decent job with my board layout/routing until the FCC test report came back *FAILED*. At least it was nice of them to put it in all capitals, made me feel better ;) After reviewing the emissions report, it appeared a majority of the emissions were at every harmonic (even...

I have seen this done on more than one ocassion for more than one...
