Is it possible to electro plate surface mount components into a pcb and would this make for better lead free solder joints ?

lead free solder and landfill
lead free solder has caused more landfill with electronics dying early than lead solder’s pollutative effect.
lead free solder not good enough for military applications, hence there exemptional status from rohs standards as regards solder, though they’re still worried about of the shelf life of electronics they purchase using lead free solder designs.
tin whiskers being a major problem with lead free solder :
secondarily : stress fractures are more likely with components that get too hot , such as happened on the apple ibook G4 motherboards, pictured below.
stress fracture dry solder joint worse on lead free solder joints:
this 3% lead that is in solder to reduce tin whisker failure and increase longevity of solder joints under heat and expansion stress in general, is probably much less polluting that having lots of electronics fail early and go to landfill because of lead free solder, in reality who knows which has done more harm, I’d probably say the landfill and lifespan / little use issue is a much bigger problem than 3% lead in the solder but maybe im wrong.
bga chip assembly in graphics card must be ended
bga or ball grid array solder graphics chip chip package attatchment methods, are fundamentally more prone to failure than other packaging and assembly methods and should be banned in graphics card assembly methods and design.
