I was designing the footprint for this FPC connector: Datasheet
The recommended land pattern is shown here:
The issue I encountered is that the pins on one side protrude outside of the pad:
I triple checked the dimensions and the outer "toes" and the "heel" on one of the sides seem fine.
Would the absence of the "heel" fillet on one of the sides be an issue? It's not that I think that Molex has provided a bad footprint but more that I fear I might have misinterpreted something.
These are the measurements on the land pattern depicted above:
I moved the pads to be 2.9mm center to center, and this is the result:
Which is weird, because the long pad is still on the short "pin". Flipping the part to match the long pin with the long pad, this is how it looks:
