            pin 2,3,4 ... you can hardly see ... when i use microscope .. its clear. ...those 3 pin were corroded.....

            i think good microscope is very important ... i use .5x barlo lens which gave 8inch working distance. today i fix another board. i had to change isl6259... after soldering i chked every single pin joint... its its works perfectly in first try ..i think in board repair precision work is very important..
