.4mm to 2.54mm Routing

autodeskguest

I seem to be having a heck of a time getting the autorouter to route

between .4mm pitch 48 pin qfn smd and 2 x 2.54mm pth header strips.

Any suggestions?

  • Hi!

     

    You can't manually route to/from the QFN48 as well. Just run a DRC on

    the unrouted board and you'll get a ton of errors. The package already

    violates the minimum clearance rules. So the autorouter can't reach the

    SMDs without violating the rules even further, hence it leaves them out.

     

    So, to solve the problem, first check the DRC parameters. Then go to the

    schematic and check the CLASS settings. Finally, ensure that the NETs

    attached to ESP32 belong to the proper CLASS.
