Hi Grant, The purpose for allowing the solder paste to reach room temp before production is to reduce the amount of water absobtion from the air. (e.g. a cold glass of water "sweats" on a humid day)The purpose for mixing is to make the viscosity more

Enlarging the "End Pads" is normally done to help accomodate the Wave soldering process... works as solder thief to help eliminate bridging on the last 2 pins to cross the wave. It is reasonable to assume that, if you are seeing cold solder due to fl
