I think this will only apply to low and low-mid end. For certain things like laptops and all-in-one the saved cost and space make sense. But there is still market in hi-end. Though prices might go up a bit. Still this does offer better opportunities for low-power devices for general computing.

I had thought that many consumer PCs had already gone the route of soldered CPU with integrated video. One market that will be very disappointed with this development are gamers who build their own PCs. They're obviously not Mac users.

Look up toaster oven ref low. Or adapt it to an electric skillet with a bit of sand in the bottom to evenly distribute the heat. Even easier when you use a laser cut mask from someplace like polulu to squegee with.

Actually, most laptops don't. The CPU inside my Dell Inspiron is in a socket.

I don't think this will make a huge difference.

PC's are well past being commodities, and are now less than 20% of the market. Most of those machines are going to businesses and schools, who have absolutely no need for socketed CPU's.

Hobbyists won't be terribly inconvenienced, because most of the time they will upgrade the mobo and RAM at the same time they upgrade the CPU, e.g. to take advantage of a new bus or new type of RAM.

This is only going to affect a very small number of users, namely a handful gamers who actually swap out the CPU, and nothing but the CPU, every 3-6 months.

Ha!
Do you have the PGA solder mask, and paste solder (and applicator) ? paste solder is Not flux. 180+ tiny dots of solder, then the chip is placed and heated (remember whey you DID NOT get chips too hot when soldering) to flow the paste.

Microscope needed.

I have no idea what any of that means. What happened to electronic discussions involving words like "breadboard" and "jumper"?

Breadboards are awesome for the home tinkerer, and jumpers will always have a place. However, you just can't get a lot of components in through-hole designs anymore, as SMD/Ts are so much cheaper to manufacture and assemble. To get around this, some really smart people discovered that you can lay down solder paste on a board, place the components, and use a toaster oven (or skillet!) for the necessary heat to cure the solder.



To make the placement of the solder paste easier, you can get Mylar stencils from places like Pololu, and then you just use a squeegee to ensure the proper thickness in the proper places.

BGA CPUs will make it so fewer people change their chips, but I honestly can't remember ever changing out a CPU without also changing out the motherboard. And if someone can use Google, they can figure out how to desolder the chip and resolder a new one on there. Not as easy as a socket, but it will help a bunch with proper connections of each trace as well as decreased costs.

EDIT: Good Tutorial

How about cardboard, some fitting and regular oven? Just place it tightly around all other components and let it desolder the CPU... Soldering it back is the interesting part ;D

Still, I don't think they will go all the way with this.

That is not too far off now that Apple is doing soldered RAM.
(Coming soon to a PC near us...)
All that remains is soldered SSD on a Tablet PC.

Give it a year.

Great, so when the ram goes out in my computer, like last week, I have to buy a new computer? That would stink!
I've had CPUs go out too, and MoBos. I just replace what is needed as I need it.
And I'm not a Geek or a Gamer, just a plain old boring stay at home mom that happens to be a control freak when it comes to what is in my computers!

I'm an enthusiast, but I really don't think this is a massive deal. So long as they don't push forward with ideas of soldered memory or 'secure' SSD's being the default. Know they were toying with the ideas for servers and low end boxes.

My little netbook has soldered mem and no spare socket, all because the vendor didn't change the model number... while completely changing the model itself. Now I have 4gb sitting about on my desk
