A4000D Motherboard cold solder reflow successful!

[danbeaver]

Chuck, its a wee bit late for your advise, and while putting a motherboard in a kitchen oven is, "Bold talk for a one-eyed fat man" (True Grit 1969), it is done and seems to have worked to the satisfaction of the owner.  He appears to have considered the outcomes and made his decision.

Bravo!  But, "Son, you're on your own..." (Blazing Saddles 1974)

Just out of curiosity would a heat shrink gun (paint remover) work?

wow congrats that's amazing:) you should go play the lottery right away because it seems your luck rate is very high right now:hammer:

Leaded solder and unleaded solder have different temperatures they melt at.  It also depends on whether Commodore used a cheap or normal mixture of solder.  

I think whoever wants to do this kind of work should take lessons and ask questions from people in the industry and they can be found on microcontroller boards.  There are fewer experts than there are hobbyists.

People should learn about temperatures, leaded solder and non-leaded solder, reflow ovens, heat reflow guns. surface mount soldering and also watch some videos on it.

You might actually need a heat sink and you can also damage components with regular soldering.

Common solder formulations based on tin and lead are listed below. The fraction represent percentage of tin first, then lead, totaling 100%:
63/37: melts at 183 °C (361 °F) (eutectic: the only mixture that melts at a point, instead of over a range)
60/40: melts between 183–190 °C (361–374 °F)
50/50: melts between 183–215 °C (361–419 °F)

PowerBall is up to $450 Million.  If you win, buy up all the rights/licensing/trademarks to Amiga.  I suspect you'll need to spend at least half of that on lawyers.  :roflmao:

I guess you will be the person to find out, but a soldering work station for SMD components runs around $100 for a basic model (from China) and you can set electronically the temperatures used.

Just because it apparently "worked" doesn't mean it will work for everyone and there is no rule that says solder will reflow evenly.  Solder joints have to be checked.

There is no rule that says it won't damage other systems.

Do I need to re-copy my posts? What do you think my posts have been saying?  At what point did I say, "this is the perfect solution?"

[ChuckT]

No.  But ask some electronics experts at Microchip, Atmel, Adafruit, Dangerous Prototypes, Sparkfun or even Hackaday and ask how to properly go about it.

[danbeaver]

Why?

[ChuckT]

Why?

I care enough about the users to more properly direct them how to do electronics and I would not put an Amiga in my stove.

[danbeaver]

But you don't care enough to read the posts?  How odd!

[zipper]

Pah, it's a common procedure especially with video cards about 5 to 7 years ago as the first ROHS compliant solderings didn't work too well. But mostly it's just a temporary solution.

[danbeaver]

Frontal lobectomies used to be a common procedure too,  but I still wouldn't recommend one

So, here is everything back together and running.
So far no glitches

Bottom tower is the A4000 Top tower is the 7 SCSI hard drives for Flyer

So, here is everything back together and running.

Impressive setup!
