Inspection
Why Does SPI Have Such Huge Tolerances?
Automated solder paste inspection, a must for most PCB assemblers, appears to use ridiculously wide specification limits. Most SPI program generators read a stencil Gerber file and set the target paste deposit volumes to 100% of the apertures’ theoretical volumes, with tolerances of +/-50% – a ridiculously enormous tolerance.
