@Icky nicely done. Hope all well under that BGA chip.

Look forward to seeing if it works or not :D
If it ain't broke, test it to Destruction.

@PhilC - no joy yet and no :fire:. Have checked for shorts and their aren't any but it isn't programming at the moment so am suspecting the MBGA soldering.

Oooh, BGA, nasty.
Collector of old Atari things:
800XL + Ultimate 1MB, 2x 1010 cassette, 1050 + Happy mod, 65XE (128k +APE Warp) & XC12, SIO2SD, 2600jr, 7800 and Lynx II
Atari 520ST (1Meg), 1040STF long button floppy, 2x 1040 STFMs + Gotek, 2x 4160STE with 32Mhz booster, ROM switcher, Mega ST1, Mega ST4, not to mention various bare ST boards for testing including a PAK 68/2 :)
Plus the rest..
Amiga stuff, Mac stuff, Sinclair stuff etc...

Yep - I thought it was time to experiment with these packages as they are cheaper. @exxos suggested we need an x-ray machine to add to our arsenal of tools :)

Or an army of nano-bots that can clamber underneath and eat any shorts (Simpsons reference there!)

How many 'pins' does it have? I assume you must have to have a pretty accurate stencil to get the solder as you need it?

@rubber_jonnie - 153 pins. The stencil worked and looking at the pads they all had paste on each pad and not too much.

Aren't those packages designed to be fitted using machines which vibrate the chip very quickly, friction melting the solder?
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Eagerly anticipating some updates and a chance to get me one.
