Explanation: Hydrated copper(II) sulfate is copper(II) sulfate pentahydrate, or CuSO4⋅5H2O . … The absorption of light energy excites an electron from water which is promoted to the copper(II) ion. This causes blue light to be emitted, giving the copper(II) sulfate pentahydrate its blue color.
Why copper for via filling?
Thermal conductivity: Filling a via with copper increases its thermal conductivity. In applications involving high heat, keeping the heat away from the board will increase its lifespan and prevent defects. Copper’s high thermal conductivity attracts this heat, keeping it away from critical areas of the PCB.
How to make oxygen free copper?
