Golden rule using the infinitely thin driver in EM simulation?

Does anyone know when - is it safe to use around thin conductor during the EM in Axiem simulation?

What the report of the dielectric thickness thickness of copper?

For loss of conductor, thin and thick metal work substantially the same.  The place more obvious thickness there where is with coupling between metal on the same layer.  The sentence that you pay for the thickness of the metal is AXIEM must solve for most unknown, somewhere between 2 and 3 times the amount.

At some point the coupling due to the thickness of the metal has a great effect on the hitch.   It is difficult to tell an exact rule when to make the change will question how far your floor plan is on the bottom and the thickness of the metal is.    What I suggest to you that do is setup a microstrip coupled simulation of line using the technology you use then sweep the distance between the lines for both a thin metal case and drop thick and see where converge the two responses.

A few other points.

1 check the option for the use of mesh edge when using thick metal.  For the most precise response and a good comparison, you want to make sure you edge the thick metal mesh.

2. I have not seen the report of dielectric thickness to the question of the thickness of copper a lot, but you can run a similar experiment, just to see if it's important.   The biggest problem here is to ensure that you get the distance between your ground plan and track on the right.  If you use the limit of the structure to the ground, this usually isn't a problem.  But if you have aircraft grounded at other locations in your stackup, you will need to adjust dielectric thicknesses depending on whether you use thin or thick metal to ensure that the thickness of the dielectric is correct.

  • How to use the second HARD drive of Satellite A210 - BP1 for mirroring

    Satellite A210-BP1 came with 2 HDD (160 GB).
    Now, I want to use the second hard drive mirrored the first, one that has Vista installed.
    This should be done without supervision and in real time - as a RAID 1.

    How can I do this?
    I also have Vista professional available and I would be willing to use 3rd party software as well.

    Thanks in advance for your answers.

    Hi Jan

    I doubt that this is possible
    Why? The point is that you need to use two hard drives in mirroring, RAID striping, mode etc technology
    Satellite A210 can't RAID. It s only a SATA controller without RAID capacity!

    Therefore, the final answer is; NO, it is not possible to use mirroring

  • I already have one zero drive for FCP 7 projects implemented.  I would use the same scratch drive for FCP 10.  Is there a special way of implementation is seamless?

    Said to implement the scratch disc so I can use the same hard drive for FCP 7 and 10 projects - something on a folder separated for 10 projects.  What are the steps to do t his?

    More details would be useful. You have already imported media in FCP7? Or you are just starting to work with both applications at the same time? What application you plan to use to ingest media? Don't try to use them both for ingest.  You can set FCPX to use the FCP7 Capture Scratch location for your support and then let the media imported in place. You can also assign a location for media to import using FCPX and then use this location for FCP7, again leaving the media in place.

    Or I totally misunderstood and you only talking about using the same drive, which is not a problem at all.

  • need to repair the startup of windows, files, but cannot use the cd-rom drive

    for the past 6 months that I had to use a return to the top of the boot disk to get windows to load so I could copy all my important files and documents on DVDs as my windows xp edition home sp3 OS suddenly stopped wanting to load normally and I'd just reformat the HD

    Last week... my browser froze causing me to have to stop by turning off the power button... to restarting my pc, my cd-rom drive is not found and now I am unable to finish to copy my important files and these DVD

    is there anyway I can repair windows without using the cd-rom drive... .. I can get in the F12 boot menu but not in the installer of F2 or F8 safe mode without using a cd-rom drive to launch the boot disk

    2.2 under Win XP home edition sp3 dell xps 210 system, intel duo core processor 4 GB ram and 500 GB HD

    It has only 1 CD/dvd-rom combo drive and 4 smaller slots for memory cards and other... I have 3 slots open usb but do not have the files of windows to a flash drive recovery

    would it be possible to make a recovery file or file on a USB stick the size of a flash drive and boot would need... currently the largest one I have is 4 GB

    Hi storm36,

    You must have the Windows XP disk to repair Windows. As the CD/DVD drive is not getting detected, we recommend you try the following steps and check the result.

    Step 1: Check if the device is detected in the BIOS (basic input/output device)
    a. start your computer and press on delete key continuously to see the BIOS.
    b. check if the CD/DVD device is detected.
    c. If this isn't the case, then unplug the unit and he reconnected inside the CPU/Tower.
    d. check the result.

    Step 2: If the device is detected in the BIOS, try the following steps:
    a. start your computer and boot to the desktop.
    b. Click Start, click Run, type devmgmt.msc, and then click ok.
    c. select my computer, click the Action menu and click scan for hardware changes.
    d. check if the CD/DVD device is listed in the list.

    Step 3: If the problem persists, restore the computer
    see How to restore Windows XP to a previous state .
    b. Once you have restored the computer, check if the CD/DVD drive is visible.

  • HP G62-355DX: recommend some course HP laptop model that can be used the same hard drive using G62-355DX?

    I have a HP G62-355DX dead, I think the hard drive is ok, so I want to buy a new laptop HP to change the hard drive, so I can recover my data and OS environment.

    Could someone please recommend some course HP laptop model that can be used the same hard drive as G62-355DX use?

    Even the hard drive can not put it in the bag laptop, but work with the HARD drive interface.

    Or is there any external HARD disk enclosure can be used to read the data hard disk, the data does not have compreesed.

    Thank you in advance.

    Hello! You need a new PC Yep!
    But there are other ways to do

    You can buy a SATA USB adapter that will allow you to plug in the HARD drive on another PC and the take-off data

    NOW YOU CAN ONLY SAVE DATA FROM THE DISK IF THE HARD DRIVE IS NOT DEAD

    Good luck!

  • How to use the SDLT tape drive in the guest OS VM

    Dear

    now, I have HP DL380 G5 Server running windows 2003 Ent. with bus adapter host SC11xe PCI - E HP which directly connected tp SDLT Tape Drive as backup server and use for the backup operation.

    I want to move the physical backup to host vmware server and EMC AX4 allows you to have a backup online and allows you to take backup offline, SDLT tape drive

    My question is how I use the SDLT tape drive in guest OS vm and vmware knows "HP PCI - E SC11xe Host bus adapter" or not.

    Please let me know how to do this.

    Kind regards

    Mahdi Bellavia

    I have a G5 DL385 (AMD of the DL380 version) with a DLT3.   I use an Adaptec 29320LPE, appearing on the compatibility list.  We plugged a HP Ultrium 920 changer using the 'old method' SCSI passthrough.  We bought the Adaptec card, because we used initially ESX3.5.  We are now on ESX4.0, but for various reasons, the configuration left the same, so I have not tried with VMDirectPath I don't know if it is possible to use the SC11ex card, but if you arrive VMDirectPath at work, it seems then you need another SCSI card.

  • Is there a way we can configure the oracle database to accept connections from particular type. For example, we may limit Server Oracle don't not to accept applications for connection to the JDBC thin driver?

    I have an oracle server which is our recovery server disaster. When I switch my application of the primary site to secondary site, we have a window of downtime during which it must implement the secondary site. When setting up the application on the secondary site, I am getting below error please take note that primary and secondary are always synchronized. The application uses the thin driver JDBC to connect to the database.

    However when I use the same user name and password to connect to the SQLPLUS it connects successfully. When I use the sqldeveloper or any other jdbc connection, it fails with the above error.


    Can someone please advice what may be the setting on the oracle server that limits connections jdbc or any setting related to jdbc on the oracle client

  • How to migrate the imac 2007 to the new iMac using the TM backup drive?

    My mid 2007 iMac does start more (gray screen of death) so I have a new iMac on command.

    I expect to use the Migration Wizard when the new machine arrives in a week or two from here.  I'll need to do it from my Time Machine backup disk however.

    The backup TM drive is a TB drive WD MyBook Studio 2 2 (physical hard drives 2 x 1 TB) in a RAID 1 array.  This is the Firewire 800 and it looks like 2 USB as well.

    The new iMac looks like it's fall in love 2 and USB 3.

    So I guess I'll need an adapter of some sort to migrate my stuff to the new iMac maybe?  Can someone advise please?

    Connect the drive via USB. No adapter is required.

    There is no test in the past, but I guess you have to do on the track:

    Start your laptop by using the MS-DOS boot disk
    Load the MS-DOS driver for external DVD drive to access
    Boot the CD of facilities here in the hope that it will market
