Electronics Manufacturing and Electronics Assembly

For automatic under-stencil cleaning there are many cleaning methods including dry vacuum cleaning, wet dry vacuum cleaning. What factors should we consider to select wet based cleaning versus dry based cleaning? The Assembly Brothers, Jim Hall and Phil Zarrow, discuss this scenario and offer their suggestions.
