Hello venkates2218,
You can manually join the air-wires (un-routed) to the points they need to go to and eliminate
any errors.
(1) Click on the "Route" icon on the left hand side
(2) Change the layer setting to what you require (top left)
(3) Click the "Wire Bend Style 1" 2nd one in, from the right of layer setting
(4) Change the width settings to the same width as the tracks already shown in your PCB layout (roughly top center)
(5) Next to the width setting, select the via shape to what you like
(6) Next to the via shapes, select the diameter of the via (I usually use: 2.1844mm, as I find this good for via size and drill hole)
(7) Next, select the drill size. It should be no less than 0.9mm, as tinned copper wire for links are usually that diameter
(8) Click the "Wire Bend Style 1"
(9) Click on the top air-wire in your layout and move it to the center TP5. You'll notice it will go over the same track. That's fine.
(10) Do the same for the air-wire below that and move it to the center of the IC pin, at the same time following the contour of the
original tracks wire bend.
(11) Next, click on the center of TP7 and move it one grid space (1.27mm) to the left but don't double click it to cancel it.
It should show a short track with your cursor still attached to it.
(12) Go up to layer setting and change it to "1 top" (red)
(13) Next, go to the track width setting and change it to say 0.6096mm
(14) Move your cursor back to the new short track you made, click the track and cross over the other tracks and follow it down
to and past the track close to where TP8 is located - at least one grid length. This track should be in red, plus it will have created
one side of your link with a via
(15) Click where you need to place it, but don't double click it. Now go back up and change the layer setting to what ever your
bottom tracks are, then change the width to the same as the bottom tracks
(16) Now move your cursor to the track of TP8, "click" and that should complete the circuit.
You can move the via closer to TP8's track if you like, but as long as the via doesn't encroach on any other tracks.
Hopefully that should solve your air-wire problem and should no longer give you any errors.
Please let us know how you get on.
Regards,
Relayer
