Desmear process: It is a chemical process where the melted resin that is deposited on the hole walls is removed. This process eliminates unwanted resin and enhances electrical conductivity through the vias. Deburr process: It is a motorized process that eradicates the elevated ends (crowns) of the metal (copper) called burrs. Any debris that ...

Burrs, being one of the most undesired obstructions generated during machining, affects work piece quality negatively in many aspects. Although deburring removes burrs, this extra process is time consuming, costly and might affect dimensional accuracy. This study investigates mechanisms, effects and variations on burr formation in most common machining processes such as drilling, milling ...

Following the lamination process, a PCB is a panel with blank, solid copper on the outer sides. The solid copper foil provides a conducting path for the plating currents that will deposit the copper in the holes and on the surface features. Leaving the two outer layers, aka "sides", unetched provides this current path.
