Hey folks so I bought a batch of charger modules (tp5200 based) to charge two 26650's in series, and it seems every single one I have hooked up either fried straight away or fried after a couple of charge cycles. Anyway, I have, after reading the internet, decided to try replacing the IC itself, along with the flyback diode that might be poor quality on the original boards.
I have the IC's, but I am concerned about replacing. I have hot air, I have got some SMT solder paste, but no stencil....
Can anyone give me tips to get a good bond from the photo supplied?
