Machine description
The Process Lens PL is an inline solder paste inspection machine which visually inspects 100% of
paste deposits on any given product in 3D and 2D and compares them to their expected volume, X
and Y position, area, mean height and shape.
It also checks for bridging between adjacent pads and coplanarity failures for a group of pads belong-
ing to the same component.
This visual control is based on the stencil's Gerber data which contains all the apertures, their shape,
size, orientation and position as well as the stencil thickness.
The Process Lens PL saves all measurement data on its hard drive. Process Lens PL also measures
the warpage of each PCB during the inspection and uses this data to keep the images in sharp focus
by adjusting the height of the Z-axis accordingly. The evolution and history of the printing process can
be visualized through the SPC (Statistical Process Control) package delivered with the machine.
