If you have a hot air station & hot tweezers, it's a breeze. If not, back to old school. Most important thing is to not damage the board and I've replaced hundreds of IC's under varying conditions as

I agree with John anyone can have that Oh no moment and when it does work it’s a great feeling. Nice thing about this group there is always somebody to help out. Glad to see more people wanting to

Definitely not alone, many times things haven’t gone right during 75 years of messing around. Big smiles when something works the first time, DIY if you can, might cost more in the end but you can

Thanks for letting me know I am not alone! This is my first attempt at building a kit. When/if successful can take my place among those who have gone before.

I've also done it. Somehow I wasn't paying attention and got an IC installed backwards in a wattmeter kit. Removing the errant device is on top of my to do list, along with getting my Hilltoppers

There's a Youtube video on surface mount tech that details removing an IC with a process that should work on through hole as well. Check it out. Virus-free. www.avast.com

We have all done it if we have done any building at all, so don't feel bad. Sent from TypeApp

Thanks, and I was being so careful!!!
