Pure (red) copper oxide is green, its not a residue its just oxidation. In your case water and heat will accelerate the oxidation process of unplated or unprotected pure copper. The best way to avoid this from happening is use a socket with tin or n

Printed Circuit Board Quality: Copper Wrap

Technical Library | 2021-07-20 20:12:20.0

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?

A Designed Experiment for the Influence of Copper Foils on Impedance, DC Line Resistance and Insertion Loss

Technical Library | 2013-03-28 16:18:22.0

For the last couple of years, the main concerns regarding the electrical performance of blank PCB boards were impedance and ohmic resistance. Just recently, the need to reduce insertion loss came up in discussions with blank board customers (...) The paper describes the test vehicle and the testing methodology and discusses in detail the electrical performance characteristics. The influence of the independent variables on the performance characteristics is presented. Finally the thermal reliability of the boards built applying different copper foils and oxide replacements was investigated.
