| how to determine the optimum solder paste height ? Ray, This is a gross misconception within the industry. There is no optimum solder paste height, per say. The effectiveness of a solder joint should be quantified in volume. Use your process as a monitor. Your apertures are probably of a different width than mine. therefor, we will both require different paste heights for peak performance. Optimum solder paste height should be that height at which you don't encounter any defects for that particular component type. Keep in mind, concern yourself with the "amount" of solder paste, not the "height." good luck and best regards, justin medernach flextronics international
