It will never, ever be as black & white as you make it out jfitzpat... You are dead wrong on numerous counts... That's a fact... Not open for dicussion... Swallow it and move on...
Yeah, leadfree is the way forward... But nope, it simply not true that it's as easy to solder... It's as easy once you have mastered it... yeah, true... But then again, that applies to just about anything right?!
The simple truth is that lead free solder requires a higher temperature, and physics say if a component can take a fixed amount of heat before breaking, the time you can apply heat is shortened when you increase the temperature...
If you apply a higher temperature to a local spot on a PCB you get higher levels of expansion on the copper layer vs the substrate, making it easier to separate them... Same applies for the legs on a component vs the silicate body...
And no... The manufacturers didn't really change their component in terms of heat tolerances... But they did change their tinning like you said...
You want me to go on?!
Face fact... Life is a gray area... And responding to "disinformation" with more of the same is just as bad...
But I wholeheartedly agree that you should use leadfree solder... Even with it's downsides... Now stop throwing stones in glass houses and carry on...
