Hi, Yes you can use a PWM (Pulse Width Modulator). This is much more efficient than a large resistor & gives you good control. Here is a sample for 12V motor control: http://www.homepower.com/files/pwmhp75.pdf

With a BGA, how much solder paste are you putting on the pads? sometimes, bridging occurs when there is more solder paste than needed during reflow.....just a thought
