Hi, most of the links do not work anymore...

The document is being updated, and once the update is complete, a new link will be provided.

it's been a few weeks and it appears the documents are still temporarily unavailable. I managed to get most of the relevant PDFs using the wayback-machine but the Gerber zip-files are not hosted there. @willzhou, would you be willing to email/post the Gerber files for the steval-wlc38rx, or any of the reference designs (stdes-wlc38wa or stdes-wlc38tws-bom) for the STWLC38 (or other ICs)?
I'm asking because i'm struggling to route all the traces from the BGA footprint. Even with filled+capped vias, some of the middle pads are tricky to fan-out. It seems EuroCircuits wouldn't be capable of producing a sufficiently precise PCB; which manufacturer does ST prefer for its eval boards?
