The increased component height after reflow | 24 October, 2002

Hi: The component height will increase on the PCB after reflow soldering. But i don't know the accurate data of the increased height. Who can help me to get it? The stencil thickness is 5 mil we used. Thanks Harriss

There are many factors that will affect post soldering height. Lead shape/type, pad geometry, fillet formation, etc... You will need to measure each type of component before and after reflow.
