Step 7Inserting the new Regulator into the circuit
This the only really, truly difficult step. And even this one isin't that bad.
There's not enough room on the PCB to have the new regulator fit where the old one was. There is also not quite enough room to have it sticking over the edge. What to do! Luckily, we do not live in a flat world!
My solution is to slightly angle it and have it up in the air. Good for cooling (the regulator hardly gets warm at all--also tested) and more importantly: It lets it fit!
Tack down one leg (making sure to check the polarity) by pressing the iron to the leg and NOT the pad. As you should all know, you heat the component not the solder.
With the extra solder already on the pad, once the leg heats up it should flow easily and stick the component down. Ah, good old lead solder. Then solder the other leg, and then the other-other leg. Easy.
I had to clip off a little of the legs to make it fit without touching the ground-plane. That's the big silver area where the old regulator used to be. You may not need to. Just don't let them touch the ground-plane that the other regulator was stuck to. Sparks and the factory packaged smoke may be released. BAD!
Also, you could also use a little bit of wire and stuff it down into the body of the radio. I don't like things rattling around inside my radio--so I chose not to do this. You make your own decisions, and stick with them.
