Automated vision inspection is among the top features of most advanced stencil printers. Other top features and process-related techniques include underside cleaning with vacuum, automatic placement of support pins and auto paste dispensing.rnIn some PCB assembly camps, vision inspection and other major stencil printer features, as well as setup process techniques, are not used. Reasons for not using them vary. For example, in some instances a stencil printer has vision inspection, but an operator simply ignores it. Other times, it's not put to use due to poor operator training. A third reason assemblers avoid vision inspection as an option is its high cost.
