Motherboard scrap prices?

BTW what solder cover are you talking about on sound blaster cards? I have boxes of new sound blaster cards.

I think he's talking about the green solder mask.

Solder mask or solder stop mask or solder resist is a thin lacquer-like layer of polymer that is usually applied to the copper traces of a printed circuit board for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads. Wikipedia

Most circuit boards have copper under the solder mask but a few have gold. There are some display boards in in certain phones I scrap that have the gold under the solder mask which means more money.

Yes the solder mask, thank you Jimicrk. the sound blasters have a brown solder mask. What is your opinion Jimicrk as far as depopulating my boards? Is it worth more in the long run to someone like me that has all the time to do it? If I just sell off the boards as is it kinda kills the hobby part for me.

My main reason for not doing it is because of the hazardous materials that are in some of the components. I don't wish to contaminate my work area or myself.
I like 520's idea. Sell your boards and buy your gold.

If you can safely depopulate boards without lead or silicate contamination then for your next batch do the math according to a buyer's price list before depopulating then compare it to what you get paid in your return for depopulated boards and precious metals returns. My own recommendation for the highest and safest returns is to take all that time you'd spend depopulating boards and use it to source more e-waste.

I thank you for your advice on checking with buyers price list. According to the list I was looking at and the weight of some of my scrap, I have been making almost nothing for my
time spent. Trimmed gold fingers $25 lb, I put to much time into a pound to get back $25. I have lots of CPU'S and found the price list just confusing. I wish I had never started removing things from the scrap. I guess my next step is to learn more about the scrap and stop removing things til I know its worth it. I still have about 100 mother boards untouched, so now i need to find a local buyer.

With CPU's you should be able to just send them to the buyer and let them sort them out for you.

520, did you check your cards for gold plating? If you do have some there is a way to remove the solder mask so not to scratch the gold if you need to.
