Thanks for the heads up, what issues am I likely to suffer with it being fake? And should I just bin it and replace it immediately? I have spares lying round al over the place.

Well, the one I got has a partially insulated earth pin, a fake fuse, very small CSA of the conductors, and I question the terminations. Bin it, never worth using a crap one.

I tried removing a few components from an old HDD board, couldn't remove any of the TQFP with it set to 400 degrees. Managed to remove plenty of 8PDIP and SMD resistors etc. I think I had too small of a nozzle attached for the TQFP. I'll be a bit more agressive in my next attempt.

I'm still not sure what temperatures I should use. At 220 I can easily solder new components with my lead solder paste, but desoldering the board from a WD HDD wouldn't budge at 22, or 280.

Desoldering is a right pain, especially lead-free. You can get nozzles specifically designed for various packages on eBay.

It could also be one of those chips that have the metal pad on the underside.

Ah yes, I did think of that but couldn't figure out how I would remove it.

Sadly I'm having no luck finding addition code to run the AT25F1024 I salvaged. My own code doesn't work so I can't tell if I killed it while desoldering it :-(

Call Atten and tell them and GET A REPLACEMENT don't fix it. You don't know what else wonghonlo did wrong.

alias_neo:
I can confirm that my station also has the fake plug with a fake fuse fitted. The fuse is so obviously fake you can see the piece of wire protruding from the end caps. Replaced it immediately with a certified one and bummed the original.

There is no point contacting atten, they're clearly counterfeit. I will contact the retailer though and make them aware.
