Take a look at the contact surface of this chip. Its from an

Can you go into any further detail than that?

Yeah, it's possible. In mass production, defective parts would be tested and thrown out. Solder likes to ball up and stick together over the pad, that's the whole surface tension thing. It's unlikely that it'll run like water to a different pad when it's liquid.

Basically: solder has suprising properties to someone who has never used it. These properties make it less likely for those parts to mess up.

zzz...

If you can't tell from the motion bur, that screen shot is from a video.

A stencil is created from the footprints on the PCB design file. Then, solder paste is wiped on the board. The pick and place machine places it perfectly.
