Dear all,

Would you please share any "spec" or industry " practice" to set the
control range of volume measurement by SPI instrument in the solder paste
printing process ?

It may be expressed as "%"  of volume as theorotical volume (volume of
stencil aperture) for different type of aperture e.g. 0201, 0402, 0.4mm
pitch QFP, 0.3mm dia opening etc.........

Thanks

Jackson
