    Hi,

    I am designing a 4 layer PCB in PADS software.

    I do not understand what is plane hatch outline.

    I have idea about plane area ???

    what is the difference between plane area and copper pour???

    Can anyone suggest me something about this??


    Thanks & regards,
    Vivek Alaparthi

    When doing the PCB layout, a plane pour or hatch pour may hide or confuse other layers. Hence one can request a temporary outline only be displayed.

    Plane and copper pour are the same thing.

    Hi,

    Thanks for your reply

    what is flood and hatch

    when I am flooding the plane area, the area is filled with copper.

    Does flooding converts plane area into copper area??

    when I click on hatch option for plane area, it is showing some error message like below

    This function can only be performed on Hatch outline

    what is this error means??

    Flood should fill area with solid copper.
    Hatch should fill area with a cross-hatched pattern (less copper).
    Sorry, I don't use PADS.

    You can specify copper pour over the entire layer or portions of a layer. The PCB software will pour around pads and traces with spacing specified by "isolate".
    You can also specify "keep out" areas where you do not want copper pour, negating the copper pour.

    Hi,

    I am keeping all the things together

    •plane area is only on split/mixed planes and the outline only
    • copper and plane area are the same (plane area shows only outline whereas copper area shows the copper fill area)
    • copper pour is used to create solid power or ground planes for better noise performance. It also reduces the amount of copper to be etched if you are etching the board yourself.

    • Flood is nothing but solid copper whereas hatch is thin copper
    • We can specify "keep out" areas where you do not want copper pour, negating the copper pour

    Correct me if I am wrong

    Hatch is not thin copper. It is a copper mesh pattern.
