1.POE use Panel plating for copper sinking process, what is the benefits by using Panel plating?
As we can see, the N-layer inner circuit can be connected to the outer circuit in multilayer PCB,the copper sinking process uses the metal palladium (Pd) adsorption hole wall to connect with the inner circuit to achieve conductivity. This process is complicated to produce and the palladium metal is expensive (50% dearer than gold), but the reliability is high and the serve-life is long. Generally, large high-end factories only use this process.
2. How to recognize Electroless Plating Copper (PTH) and Conductive Adhesive?

Conductive Adhesive also called black hole, it can be found on the NPTH hole wall. The color of panel plating copper is the fiber substrate itself, and the Conductive Adhesive has a
black glue attached to the hole wall.
