Hi all,

We now use wlcsp package to build pcblib,but we found some pins were not in a straight line and no mark spacing ,so we can't build it.

Local place attached.

Please help to confirm those pins are in a straight line or not,it's better to provide pcb file .

Thanks,

Leo

Are you building a module? For normal PCB layout, the BGA should be used instead.
