So, having had one of those SMD-friendly infra-red oven heaters bought for me as a birthday present, I'm trying to get my first ever BGA pcb made, and I'm finding it more difficult than I'd expected. It's been pretty easy to get PCBs manufactured before, so I'm wondering if I'm doing something fundamentally wrong...
There's an image of the prototype board (it's basically a pin-header mount for an ADV212 part so I can easily test out my connectivity) at
My problem is finding somewhere that can drill such small vias (pcbpool's DRU file prevents this, as does SunStone's, as does custompcb.com, as does pcbzip.com, as does silvercircuits.com, as does ... you get the picture). So, with no-one being able to manufacture it, and this being my first ever BGA, I assume I'm doing something wrong.
So: o Is there a PCB manufacturer who can drill tiny vias like this ? o Am I doing this wrong ? Better: How am I going wrong ? :) o What SMT pads / via sizes would you use for a 1mm BGA part ?
Ideally I'd like to use a PCB manufacturer who takes Eagle BRD files - I think I failed dismally at making the Gerber 274X files for pcbfabexpress.com, though their customer service hasn't been wonderful so far, so I'm not sure...
Anyone any ideas ?
Any help gratefully received :)
