OPTIMAL IMAGING SYSTEM AND METHOD FOR A STENCIL PRINTER

摘要

A stencil printer for depositing solder paste onto an electronic substrate includes a frame and a stencil coupled to the frame. A dispenser is coupled to the frame, with the dispenser and the stencil being configured to deposit solder paste onto the plurality of pads of the electronic substrate. An imaging system is configured to capture images of regions of interest of at least one of the electronic substrate and the stencil. The stencil printer further includes a controller coupled to the imaging system, with the controller being configured to control movement of the imaging system to capture images of regions of interest of at least one of the electronic substrate and the stencil extending generally along a first axis before moving the imaging system in another direction. A method for dispensing material on a substrate is further disclosed.
