Does anyone know of a 0.3mm pitch BGA or WL-CSP or anything with a 0.3mm pitch?

• I need one for testing a PnP machine. It's very hard to hunt something down just by package, so does anyone know of anything with a 0.3mm pitch? BGA preferred. Or clues where to look?
  Thanks!

  Smallest 'real' part I've designed with so far was 0.5mm BGA (eMMC chip) and that was 'fun' already for my pcb layout contractor, hate to imagine 0.3mm pitch and trying to route stuff out from the middle.
  
  cheers,

  I have a feeling that the prices for those are going to be either [1] ridiculously expensive, even more so than regular ICs, since they're quite specialised parts, or [2] ridiculously cheap, like resistors or other passives, since the NRE is basically zero.

• Smallest I have used is 0.4mm pitch (BGA) - WM5102ECS/RCT-ND

• Lattice have some ultra small FPGAs with 0.35mm spacing:

• 0.3mm pitch, oof. Theres a big difference between 0.5 and 0.4, I cant even imagine how much swearing I'd do at something 0.3mm

• An 01005 size component is 0.4 by 0.2mm, would that do?

  This is the route I'd go. Saying "We can place 01005s successfully!" is more commercially valuable than saying "We can place 0.3mm pitch BGAs!" as there's a lot more demand for 01005s. I've looked through my part history, and the smallest I've placed lately are 0.35mm pitch devices, which are reasonably common. (ESD filters, single-gate logic, and others favor that pitch. Basically anything with a significant sales potential into cell phones.) TI don't even make any 0.3mm pitch packages as far as I can tell -- they have two drawings on the books (YHC and YHD) but no active products with them; YHD doesn't even have a publicly available drawing. 0.35mm, in contrast, has loads of parts available.
