800XL on Northridge Fix Youtube channel

[Rybags]

Just fresh in about 15 minutes ago.  First part of the video is fixing a Ryzen 9.  Second part ~ 11m 16s is an 800XL motherboard.

 

I've not watched it yet so can't decribe further.

OK, watched it.

He uses hot air with flux applied first and some low-melt solder added to the pins from the back side.

Amazingly little damage, the vias look to have survived OK, maybe some mask lost from adjoining traces.

Then cleanup with standard iron and wick.

 

I commented on it - it seems probably overall quicker than using the iron on pin then pump from backside method.

 

Would be interesting to see him tackle an XE though.

His channel is really good for microsoldering. This chip is probably the size of about 20 of the usual ones he deals with!

It's the 4050 from the video circuit.  There's a comment in there thanking him, this job was in aid of a UAV install.  I'm sort of surprised he just didn't also get Alex to put a new socket in also, though in all possibility it might have been an extra 50 bucks.

 

Yeah - most of the work he shows seems to be refitting smaller components like SM resistors and caps.  And a huge amount of HDMI and USB board mounts as well as MOSFETs for laptops and graphics cards.

 

The 4050 - 5 pins worth would probably be about the size of the side of a MOSFET you'd see in a laptop.
