Oh, the agony of defeat...
I could use some guidance on this one.
I made a PCB layout using the RIMU PCB layout software, and sent the board to ITEAD Studio.
I've done this with several PCB's, and everything has worked out great, and I've been very happy with the PCBs.
I just received my last submission, and it is a panalized PCB with 8 "boards" on the one submitted board.
7 of the 8 are fine.
One of the little boards is an XmegaE5 DIP module, and the layout looks fine on my PC, but on the actual PCB the pads for the micro's pins are all shorted together!
The pads for all of the other chips look fine.
What happened to this particular chip's pin's pads?
About the board:
The main project on this PCB is the 8 x 11 cm board, within the ITEAD 10x15 cm board.
One can cut the main project's PCB in half and have just the micro / GLCD / wireless part, without the other analog stuff for this particular project, if desired.
(i.e. yet another Xmega mini-development board)
Being > 10 cm meant that I had to get a 10 x 15 cm PCB from ITEAD Studio.
Not a problem, I just filled in the board's boarders with a few other mini-PCBs.
(XmegaE5 Dip, FTDI USB Bridge, Digitial LED breakout, STK500 2x5 header to PCB DIP, etc.)
Anyway, I've never had this problem with one of my manufactured PCBs.
The layout looks fine, the solder mask looks just like the solder mask on the other chips, including the other Xmega on the PCB, and the FDTI chip.
Anyone familar with this problem, or have any suggestions?
I've submitted a Tech Support ticket, but haven't heard back yet.
