Alliance M29F800FB5AN6E2 weird behavior #9

I Built your adapter with M29F800FB5AN6E2 (alliance) and I was struggling to do in a trusty way:

checking id
erasing
verifying blank
program
verify after what programmed

On one of the test I heat the pcb with the hot air soldering station and while "more than warm" I was able to perform all operation and also use it on the A600. Once cool down failed again...

Is it the flash? flux? something else you can imagine?

I answer myself and close the issue, the memory is extremely sensible to the flux, I iterated alcohol with a thin hair toothbrush (the other I had could not get well between pins) and hot air. Now I have a dual KS for my A600! Thanks!
