Please post some screenshots to illustrate your problem.

Now that I have gone back. I am trying to understand maybe what I did or didnt do (impossible) Resolved to recreate with RECT and replace PAD~RECT and rebuild the PCB. As you can see, the track covers part of the card edge.  It is worse on the solder side where the traces are mirrored on the shorter card edge.          

@gammaray, Sorry but your screenshots are too close up. I still don't understand the problem. Why are you worried about what the EasyEDA Source file calls the pads? Surely the issue is what the pads look like on the PCB.

Solder mask layer will cover card edge when activated for the TRACKS that extend to middle of PAD-RECT

Why? Tracks normally terminate in the centre of pads. The solder mask is automatically removed over the whole area of the pad plus a small margin outside the pad. This is true wherever the track to the pad is terminated within the pad.

@andyfierman Wonderful that is good news! But in the mean-time, I did the coding to turn the PAD-RECT to a RECTANG generating the JSON coding. Now I won't have to debug it.

If you have changed the EasyEDA Source then you **MUST** check your Gerbers very carefully using **gerbv** and not the JLCPCB Gerber viewer. [https://docs.easyeda.com/en/Export/Export-Gerber-Files/index.html#Gerber-View](https://docs.easyeda.com/en/Export/Export-Gerber-Files/index.html#Gerber-View) I'm not familiar enough with the json code to be sure but the risk is that you have changed the status of the pads from pads to a copper solid region in which case what I just explained about the solder mask being automatically removed from the pads does not apply and you will end up with solder mask over the contact areas. If the pads look right in the EasyEDA PCB Editor window then you would be best to leave the EasyEDA Source file alone.

Continuing on the pad discussion... (I am beginning to think the nature of the different geometries have been changed with the upgrades to EasyEDA to simplify.)  Why would a pad have a paste mask layer on it? The white object is the pastemask layer object congruous with the top layer pad copied into practice area of PCB. 1\. Is it because the pads are to be "coated" with solder? 2\. Or should a pastemask only be present for SMD? 3\. What happens on paste machine if a paste mask is present on  layout but has a 0 mil thickness which I changed from 4mil to 0?  A similar problem happens with the rectangular shaped pads I created in that they have a solder mask present on that layer with current 0 mil thickness. 1\. Pads typically do not to have solder mask I gather from per our previous discussion\.  This is accordance with my design \.  But I am not sure if I selected create solder mask or this was default or should be deleted\.
