Clean Circuitboards

Value
Circuitboards, including motherboards, cards, memory boards (SIMMs, DIMMs, Cache, etc), hard drive and other controller boards, are one of the most valuable recycling material FreeGeek deals with. The more we can categorize them (dependent on space and time), the more money we can get from them. For example:

The gaylord of motherboards + cards + other goes for around 85c/lb. The gaylord of hard drive controller boards goes for around 1.25/lb.

The price is dependent on how much gold the material has, but is not dependent on the specific box, so a processor left in the motherboards bin gets us nothing.

Please note that we may be able to get more for memory cards because of the gold fingers and their densities than they currently get in the motherboards bin. Also note that cdrom controller cards could probably go in the hard drive controller bin, but the work of extracting them is likely too much. Floppy drive controller boards, however, are likely better off in motherboards.

Also note that no one has explored whether daughterboards would get a different price from motherboards.

Clean for safety and processing
Lastly, for clean circuitboard bins to make everyone happiest, the following things need to not be in them:


 * batteries. According to Hallmark through Jhasen, Dallas Clock Batteries are fine, but the NiCd barrel batteries are not (along with button, alkaline, etc)
 * physically large capacitors, heatsinks, or transformers. These boards go in motors unless the components come off. The heatsinks are almost always aluminum (some copper). The transformers are copper around ferrous, and we don't know what to do with them better than motors, though we should explore it.
 * Steel faceplates.
