Frequently Asked Questions
Are these edge connectors sorted by original board type or era?
These pieces are mixed cutoffs from various circuit boards and memory modules, featuring varying segment widths, lengths, and contact configurations.
What should I expect when purchasing this scrap material?
This parcel is sold as raw electronic scrap for material recovery, consisting of the physical cut PCB edge segments shown in the photographs with no guarantee of specific gold yield.
The circuit boards are long gone, but the heavy plating on these contact fingers still has work to do. Hand it over to your beaker or kiln and see what comes out.
