Questions on PCB manufacture

Former Member

Hi all,

 

I am close to getting my PCB manufactured, however I have a few questions to ask regarding my board.

 

It mentions in manual (V6, page 281) that you should leave 2mm free of Copper around the edge of the board.  I have done a Copper pour (ratsnest command) for top and bottom layers, and the gap is 50 mil not 80 mil - how do I change this to 80 mil?

 

Page 281 also mentions identifying Component side and bottom side with CS and BS.  I have done this on layers 1 and 16, but when I run DRC it comes up with 2 errors:  No real vector font, and Width.

 

Finally how do I apply Fiducial marks to the board? 

 

Hope to hear from you soon,

 

 

Cheers,

 

 

Osman.

    Hi,

     

    texts in copper layers should be writeen in vector font. That's a property of the text you can adjust. I suppose you used proportional font and this will result in a different view on the board after the manufacturing process because Gerber plotters can use vectors only for drawing. That's the reason why EAGLE shows an error there.

     

    Concerning the distance between copper and the board contour: There is a Design Rules parameter (Distance/Copper-Dimension) that takes care on this. Basically you can also use the t/bRestirct layers for this as well.
