Surface Pro 4 Owners Are Putting Their Tablets in Freezers To Fix Screen Flickering Issues (theverge.com) 87
Hundreds of Surface Pro 4 owners have been complaining about screen flickering issues on their tablets, and many are putting it in freezers to "fix" it. From a report: A thread over at Microsoft's support forums shows that the problems have been occurring for more than a year, and most devices affected are out of warranty. Dubbed "Flickergate," a website to report the issues claims at least 1,600 Surface Pro 4 owners have experienced the screen flickering problems. The flickering appears to be a hardware issue, which occurs after the device heats up during use. Some owners have even started freezing their tablets to stop the screen flickering temporarily. "I get about half an hour's use out of it after ten minutes in the freezer," says one owner. Another user posted a video showing how the flickering stops as soon as the Surface Pro 4 is placed in a freezer.

High performance ICs and minimal cooling result in high rates of change in temperature. This will put significant strain on the solder contacts. It is safer when parts heat up slowly so better cooling could prevent the damage from occurring.
Alternatively, Intel could modify their turbo mode so that it not only limits maximum temperature but also maximum rate of change in temperature. But before I place all the blame on Intel, do these things not contain NVidea GPUs? If so, that is the likely point of failure.

So, we've got one company (Apple) that gets dragged over the coals when they introduce throttling to avoid issues related to hardware wear (Apple throttle to avoid using more current from a battery that can not provide it), now we have Microsoft (maybe) getting dragged over the coals for not including any throttling in order to avoid the rapid heating of the hardware that induces wear on the components. The computer industry is damned if they do and damned if they don't.

Genuinely curious on how to do this without frying the chip/board. Even when I have things sent out for (allegedly) professional rework, they still occasionally screw it up (cold solder, solder bridge). Do you have a thermometer to monitor the component, or do you just "gut feel" it? With a heat gun, it feels like you'll get some pretty uneven heating, so to make sure everything melts, you might get some hot spots that exceed the max reflow T of the component.

Soldering today isn't using a soldering iron and 60/40 solder.
It's precision stenciling solder paste on a PC board, using "pick and place" equipment to stick the components in the solder paste, then ramping up the while assembly's temperature in a controlled fashion so it doesn't boil solder paste and spatter on adjacent connections.
We won't get in to double sided boards with through hole components here.

I couldn't agree more!
RoHS solder has absolutely NO PLACE on my home workbench, and it is quite telling that where high-reliability is paramount, (e.g., Aerospace applications), and where lead is an essential part of an essential component (e.g. Automotive batteries), that RoHS was "exempted".
And other posters, please spare me the bullshit that car batteries can be switched to LiPo. They can, but not cost, or size, competitively.

I've seen hundreds of the fail due to this mechanism in my life as a failure analysis engineer.
One bank in China had over 100 HDDs in their array fail in a month.
Incubation period for the failure is temperature and humidity dependent. Typically, it takes 1-2 years to fail.
We performed EDS analysis to confirm the situation.

Lead Free solder (aka RoHS compliant assembly) is not universally mandated in every application, for example it's use is banned (prohibited) in most aerospace and military contracts (you have to certify no lead-free solders are used), and with NASA. Also lead solder is allowed in any automotive application. There are multiple reasons for this, but essentially it boils down to reliability.

It has nothing to do with lead in solder. The only thing that lead free solder needs to work properly is a different temperature profile, and those profiles are well known and published by the companies manufacturing not only the solder but also the packages that will be soldered. Man we've been fixing cold solder joints since back when we poured lead into our gasoline tanks. Some companies fuck up some production runs due to poor quality control.
