Georg blew out the signal generator on his DSO nano portable oscilloscope. He brought it back to life with a new buffer chip, his repair guide might save your nano too:
Spotting the chip on the board is very easy. It’s in an SMD package but fortunately a rather large type. So, although I have no specific SMD equipment I was able to desolder it. I treated all pins with desoldering wick and afterwards slid the blade of a very thin knive under it while heating the pins.
Hi,
I also fried my signal generator, but which smd package is it on your picture?
Regards
Peter
Why does the signal generator chip get fried ? How can I prevent it?? Would appreciate a an answer.
