Abstract
A package-on-package (POP) electronic device may include first and second packaging substrates, a solder interconnection providing electrical and mechanical coupling between the first and second packaging substrates, and first and second sealing layers between the first and second packaging substrates. The first and second sealing layers may be respective first and second epoxy sealing layers. Moreover, the second epoxy sealing layer may include a solder flux agent, and the first epoxy sealing layer may have a lower concentration of the solder flux agent than the second epoxy sealing layer.
