I've just had my first experience with Kester 96/3.5/.5 solder paste and I am impressed. The paste did a better job of reflowing than the leaded solder paste I am accustomed to. Not only did the MCU lack solder bridges, the ADE7753 with its much finer pitch reflowed perfectly as well. The leaded solder usually required an additional pass with solder braid and some components like 5mm TQFP-32's were very difficult to get done right.
I've put in an order for the same solder in wire form from Techni-Tool. Call me a happy camper.
