Via In Pad - Conductive Fill or Non-Conductive Fill
www.4pcb.comof the padstack structures move either with or against the adjacent board laminate material, which can lead to stress fractures and possible electrical opens in the very worst cases. This consideration naturally favors the non-conductive epoxies as their CTE is a better match with the laminate therefore making a more reliable overall structure.
