Need Repair Work: Replace PCM3060

I'm willing to bet my PCM3060 is either bad, or I traumatized it, and I need to have it replaced. I don't want to fool with this myself. I'd have to buy the heatgun, and gamble I could do it right without burning my house down.

I observed all ESD precautions, and this is my 4th SDR kit (2 Softrock Ensemble RXTX's, and another Peaberry). In 50 years of homebrew and kit work, this is the first time I've needed outside help. :-(

That said ... this is a great kit! I may build a third one some day.

I thought my pcm3060 was bad and bought one of the $50 heat guns off eBay and it worked fine. Used it several times on other chips that I thought were bad. Never mind that all of the problems turned out to be elsewhere (USB drivers, etc). They are pretty useful tools.

Can you recommend a specific gun? I'd be willing to pay bust-out retail. :-)

I pride myself on being good with solder, but lifting that SOB isn't safe with my current equipment.

It's not a recommendation but here's the one I bought (now down to $41 including shipping):

I used the small nozzle.

It works like magic. All the pads are clean and intact. I deleted the first 2 steps: flux, and over-solder. I had already wicked it dry, in hopes that it would just fall off.

The 30 gauge wire from the kit slides under the pads.

Now all I need is a new PCM3060.
