WebThe NSMD type land pad is recommended for the PCB BGA footprint. In addition to the top surface of the land pad, the reflowed solder paste will wet to the side wall making a mechanically stronger solder joint than the SMD type pad. The smaller NSMD land pad also leaves more space for routing traces between the land pads. It has been shown that

Web8 mrt. 2024 · There are two common types of BGA pads: Solder Mask Defined Pads (SMD) and Non-Solder Mask Defined Pads (NSMD).
