How I Learned to Solder SMD Components (Part 2). How to recover the conclusions of TQFP144.
Last time I managed to break two legs at FPGA EPM570T144. And all would be fine, but on one of them sits a TMS signal, i.e. Without this, the code cannot be poured into the chip. And it turned out that due to the fact that when soldering, I too pressed the soldering iron with a sting on the conclusions (lack of experience, or maybe the hands are crooked)). In this video, I am trying to fix this thing, although also not without jambs.
The video cut as much as possible, it turned out to be five times in time.
Initially, the project was conceived quite voluminous, namely the implementation of various circuit solutions of the ancient ZX-Spectrum computer on the FPGA. But since the debug boards in our stores cost not reasonable money, and on Aliexpress the toad strangled them to buy, decided to solder on its own.
On this channel I plan to consistently cover the progress of this project.
