Traces with no round egde

autodeskguest
autodeskguest over 17 years ago

Hi,

 

when using large traces their ends are rounded. This is a problem in

some smd situations.

 

For example, see this picture:

 

http://www.students.tut.fi/~kontkant/cont/ele-a3977/005-intro/telok3.png

 

Note the large traces at both high corners of the smd chip in the middle

of the pcb. The guy was able to connect them to the pad without. If I do

the same the edge will be rounded and this leads to shorts the nearest pad.

 

How to have sharp edges at the ends of a trace?

 

Thanks

Marco / iw2nzm

    For any traces larger then 16 mil I use named polygon's.

    How did you do this print? Not manually I hope?
