Plating process (18)
Uneven Plating Film: Poor conductivity -> Device repair. Weak agitation -> Review spray pump settings / Nozzle cleaning, filter replacement. Weak agitation or blocked nozzles and filters can cause uneven plating film. High current density -> Reduce current density. High copper concentration -> Partial descaling / Dummy plating. Low sulfuric acid concentration -> Add refined sulfuric acid. Less a..
