Project: HDMI/DVI out for STFM

[PhilC]

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

Look forward to seeing if it works or not

@PhilC - no joy yet and no . 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.

Oooh, BGA, nasty.

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?

[Icky]

@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?

Ouch, that gonna be tough to get right, good luck sir!

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