The boards are expensive because they are your product... covered in circuitry. A 2% scrap rate costs twice as much as a 1% scrap rate. Say the parts on your consumer electronics board cost $5. A machine that makes 99% good boards and 1% bad boards

That is possibley CTE mismatch between QFN and PCB material, the thicker PCB the higher fail rate.
