    Re: PCB land pattern standard

    if the part is a standard package part, I use what is in the library of the cad system, if I have to create the foot print I follow the manufactures guide-line in the data sheets.

    you can get more information from http://www.pcbstandards.com but the IPC recommendations are the most logical and best documented.

    If you do not want to follow a standard then you can of course use your own such as

    manufacturer_type_pins_shape_packageno

    like PH_24_400mildil_phso24

    Biggest problem you will find is that most manufacturer has used their own method of package naming so a 14_SOIC for philips might not be same as for ti.
