Solder paste bricks should ideally form crisp, uniform rectangular shapes. Curved tops like "rooftops" or dipping "saddle shapes" signal poor release from the stencil or inadequate paste volume.

Explains exact visual benchmarks for missing paste, excess paste, bridging, and peaking. and fully automated printers
Historically, standards like IPC-A-610 focused on the completed electronic assemblies after the reflow oven. IPC-7527 acts as a massive upstream prevention asset. Because roughly 60% to 70% of all SMT defects are traced directly back to the solder paste printing process, controlling this step via rigid visual standards drastically eliminates downstream rework costs.
