I did this. Baked it with a nice cheese and bread crumb topping ... seems like it made things worse.
Next time, don't put the tarragon cream sauce on until after you bake it.
If it's because of lead-free solder, than thats pretty damn stupid... How much lead could be in a laptop? Apple's laptops have never had great thermal management, they are thin beyond necessity and that means more internal heat. No wonder this miracle solder cracks.
They're really just doing this to please the eco crowd so they can display their famous environmental stats on each keynote.
Don't blame the manufacturer. Blame Europe. Electronics manufacturers use lead-free solder because the European Union's laws
require it. The law in question, the Restriction of Hazardous Substances (RoHS) directive, effectively prevents electronics manufacturers from shipping anything to Europe if it contains lead-based solder, unless that solder is solely inside of sealed, high-temperature components.
Unfortunately, GPUs are too big (physically) and get too hot to work well with lead-free solder. The extreme temperature changes cause thermal expansion, which fractures the more brittle lead-free solder joints. Worse, the RoHS ban on lead-based solder been an absolute disaster for equipment reliability worldwide, because no manufacturer wants to have to run a separate manufacturing line just for Europe if they can avoid it.
What Europe really needs to do is overturn that aspect of RoHS and replace it with mandatory requirements for recycling in a manner that prevents lead contamination of groundwater, etc. Consumer electronics all around the world would be much more reliable if they did. And the environmental damage from all the extra electronics junk that RoHS causes every year far exceeds any (mostly theoretical) benefit provided by the ban on lead-based solder, so as environmental laws go, this one was a total disaster.
In the meantime, companies everywhere should be encouraged to stop soldering their GPUs to the motherboard. Even before RoHS, GPUs were a dubious component in laptops. Now, they are just a nightmare. It would be much more sensible for manufacturers to place the GPU on a separate daughtercard alongside the main board, so that when (not if) the next round of GPUs starts to fail because of the RoHS plague, they can just swap the GPU board with one based on a newer component.
Using a daughtercard for the GPU probably wouldn't add more than a buck to the BOM cost, and given the staggering number of GPU failures over the past few years and the high cost of those failures (particularly in terms of their impact on customer trust), I would think that such a change would easily pay for itself.
