Where small components stand up on one end during reflow. Solder Bridging: Where solder shorts two adjacent pins.
Official copies are available for purchase through authorized standards distributors: IPC-7351 and SMD Pad Shapes - PCB Libraries Forum - Page 2 Ipc-7352 Pdf
IPC-7352 still uses the proven methodology of calculating land patterns based on component dimensions, tolerances, and fabrication allowances, but the "target criteria" have been tightened. The standard offers better calculations for and heel fillets , ensuring that the solder joint has the optimal volume for strength without bridging.
