Let me put my two cents into this argument..After being part of many extensive studies conducted to determine the benefits of solder paste inspection, there has never been a case where the customer concluded that paste inspection (Height or Volume)wa

In order to understand your printing process, you cannot rely soley on 2D inspection. By implementing 3D-true volumetric measurement, a more comprehensive approach to correcting the process variation can be established. True volumetric / 3D inspect

Start with your board first. Do you have resist/mask between the fine pitch? Is the finish HASL or a flat surface? If there is no mask/resist between the fine pitch leads you may want to reduce the apertures 5%. If the board is HASL, that means yo

You need to perform process a capability study prior to putting these controls into place. Cleaning a stencil after each pass will get ugly, solvent residues remaining in apertures etc. 2D inspection is good. Change paste every hour will get very
