Surface Mounting Hidden Pins
Inspired:
I am new to electronics. I need to repair a device. The component is rectangle with without pins. The connections are hidden when it is mounted. The connections on the bottom are silver and flat. I was told that I need a device that uses hot air to mount it. Is it possible to mount the component with a soldering iron?

Sounds like he's talking about a BGA package.
digsys:
Sure does. Sorry mate, it's even a tricky / delicate operation with a proper heat gun / nozzle. BGAs (assuming) are bastids to solder / unsolder
without good equipment incl solder pastes / fluxes etc

x2 on this reply. No way will you replace that package with just a soldering iron. You might get the old one off, but you'll probably damage the PCB in the process, and then... how will you heat the solder balls on the bottom of the new package, when they're literally hidden and inaccessible with a soldering iron?
Not trying to be a downer here, just honest. Some things require the proper tools. BGA's are one of them.
