This is the very beginning of a diy page on the (stupidity of) breaking down a board to the raw pcb.
This will cover 99% of boards but I chose a damaged metal socket mobo for this.
Simply because when /I/ finish pulling it all down /I/ won't be loosing anything. I've got buyers in place for these various electronic components since I deal with enough volume of this stuff loose doing repairs.

First I say yet again if you refine at home you MAY break even and you'll probably loose money.

Second taking ANYTHING off any board other than heatsinks and shields is probably a loosing proposition for the vast majority reading this.

Finally the values I'm giving are today's (time that moment) rates and are based on having HUNDREDS Of lbs of each type. Not 6 ounces or a pound.
Bringing 6 ounces of CMCs to anybody is just going to annoy them.

Finally I'm in no rush to finish this. I'll take photos as I go and post them as I move along but this isn't going to be a priority project.

This is the post where I list the steps in order in text with notes.


Step one
Of vital importance if using the rest of this yourself.
Remove any and all canister capacitors.
They contain oi. The oil is under pressure. The oil is toxic (though not deadly or even dangerously damaging on its own). It smells terrible and is harder to get rid of than skunk. And later when heat comes to play boiling pressurised oil flying at you is never fun!

Remove any and all heatsinks you can. Anything you can't targeted heat from a heat gun on 100• or less, get them off. All they do is slow the process.

Uh. No
Ohkay so this is no longer doable for me in my old method.
20+ years of ignoring respiratory safety coupling with smoking has left me with both copd and pneumonoultramicroscopucsilicovolcanoconiosis.
15 minutes with a heat gun and I'm coughing up blood and choking so it's just not going to happen.

The alternative is a reflow and that's going to cost me over $20 in supplies and electricity so...
don't fudge motherboards.
My original intention holds true though that totally scrapped each and every individual component at it's elemental base a metal socket mobo would yeald apx $2-$3 at today's rates.
There's a place where even I draw a line of safety.
