Hello ; Is the SDA pin of the sensor is connected to pin D2 in your schematic ?

Check in the Design Rules that your trace width and clearance are small enough to pass through the gaps between the pads.

@JLCPCBsupport No, it's connected to the unconnected trace below. @andyfierman I set the trace width and clearances to an acceptable range. I also disabled all the DRC checkbox's so they shouldn't be affecting anything.

@julian1barbera, Have you set the grid snap to a small enough value (or turned it off) to allow the trace to get between the gaps without hitting a clearance limit?

@andyfierman Spal is at 0.001mm

Spal? You mean snap? Your project is private so only you can see it. Can you make and post the url to a public copy of it or at least the problem area?

@andyfierman Sorry, typed that out too fast! [Here's](https://easyeda.com/julian1barbera/uimu-lite) a project link.

I said: "Check in the Design Rules that your trace width and clearance are small enough to pass through the gaps between the pads." Your reply: "I set the trace width and clearances to an acceptable range. I also disabled all the DRC checkbox's so they shouldn't be affecting anything." No you didn't and yes they do. :) You need to re-set your Design Rules appropriately: 

@andyfierman Thanks!
