It is not hard to see how the components could be rearranged to improve the layout.ĥ Instrumentation amplifier – double-sided board The power tracks are excessively long in particular. It is a poor board in many respects despite the successful routing. Put your name on the bottom etch layer, run a final design rule check, save your routed board and make a coloured plot as before. A via can also be formed using a pin-through-hole component but not at a connector because it covers the top pad. Cross-section of a double-sided printed circuit board showing free vias formed by a plated-through hole and a wire through a non-plated hole soldered top and bottom. If none of this works, get advice from a more experienced PCB designer.įigure 19. Rearrange or reorientate components to make the ratsnest simpler and ease the problem before trying the autorouter again. Quit from PCB Router without saving, or reload the previous version of your board in PCB Editor. Can you rearrange the components to solve the problem? Often one particular track prevents successful routing. If you are far from success, look at the layout to see where the problems lie. Choose Edit > Delete Wires > All Wires from the menu bar of PCB Router or reload the unrouted version of your board in PCB Editor.Ģ. It is best to unroute the board and begin afresh.

For the one-sided board there is only the suggested direction of tracks. If routing has almost worked (only one or two unrouted segments), try changing the hints given to the router. Here are some suggestions for helping the autorouter.ġ.
