Quoted from hoby1:
Who says they cant be fixed..... I have an AMAZING friend that can do extremely intricate surface mount. Seen him replace those 60/80 pin surface mount ICs on Sam flawlessly...
Ditto^^ Don't know why people think that. Other than proprietary code being a possible issue, they just use off the shelf parts that anyone can buy. If there's a BGA part somewhere on any of the boards, then that would be an issue too. No easy way to unsolder/resolder a BGA.
I haven't heard of Stern removing markings from some parts, are they? Some manufactures have been known to do that.
