In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.

Hi We are experiencing different failure modes between leaded and lead free through hole assemblies. The boards are PTH. In the case of lead free boards we are seeing fracturing of the component legs much earlier than we do with leaded assemblies. Note these are NOT joint failures but fracturing of component legs. Has anybody else noticed a similar effect and how have they resolved it.
Thanks in advance
