Expand track width after component connection
1300 5

Hello, I am using a standard 2 pin screw terminal connector on one of my pcbs \(con\_terminal\_block\_02\-5\)\. The variety I have are supposedly capable of handling 10A\, though I will only be using up to 7A\.  Track width calculators tell me that I should be using a track width of around 170mil\, however easyEDA will not allow me to make the track over 90mil wide\, I am assuming because it would be interfere with the opposite pin of the terminal connector\.  I think I really need the track to be 90mil at the pin of the terminal and then expand to 170mil for a stretch before reducing again to make its final connection\. In easyEDA it seems like the tracks can only be a single width for the entire length of the track\.  Is there any way for me to expand the track width mid track? Thanks -Michael

Hi You can add the solder mask and solder the track to capable of handling 10A [https://docs.easyeda.com/en/FAQ/Editor/index.html#How-to-add-solder-mask](https://docs.easyeda.com/en/FAQ/Editor/index.html#How-to-add-solder-mask)

Or you can place the solid region to cover the track to increase the width

Draw a 90mil track from the pin to just far enough from the pin to give 170mil clearance from the end snap vertex of the track to the pin. Then draw the rest of the track to the final end point. This will inherit the 90mil width. Select this segment and reset the width to 170mil. Alternatively, set the routing width in the canvas properties to 170mil and then draw the rest of the track.

You can also of course route the track on both sides of the PCB if space allows.

Thank you for all the suggestions.  I tried andy's first suggestion and that seems to work.  I just need to draw the track in a couple of different segments.  Routing on both sides of the board was a nice idea too. Michael
