Motivation: High reject rates for PCBs due to specification non-conformances Multiple rebuilds causing impactful schedule delays + Copper Wrap + Wicking + Etchback + Annular Ring Are rejected boards reliable? What are PCB quality requirements for? + Reliability: fewer cycles-to-failure? + Manufacturability: define threshold of modern manufacturing capability?

In the present study, a model of closed-loop recycling of copper from PCBs is demonstrated, which involves the sequential application of bioleaching and electrowinning to selectively extract copper. This approach is proposed as part of the solution to resolve the challenging ... doi.org/10.1007/s12649-020-01128-9
