CHAPTER 8 2D INSPECTION
MODULE OVERVIEW
Introduction 2D Inspection (2Di) utilizes the machine vision system for accurate detection of
paste on the board and stencil after printing. When this option is enabled the
board and stencil can be inspected for various aspects of printing as listed in the
table below.
When certain function keys are selected the existing machine status page is
replaced by a Graphical User Interface (GUI). The GUI allows the user to setup
and navigate 2Di sites quickly and easily.
Purpose By monitoring the printing process, 2Di ensures the continual quality of board
printing. 2Di, if licensed, verifies the correct paste coverage, alignment, bridg-
ing, volume, blockage and smear, (figure overleaf details).
If there is insufficient paste on the board, paste dispense and reprinting the board
operations can be undertaken. If there is too much blockage or smear, the stencil
can be cleaned automatically.
2Di optimizes the cycle time by eliminating unnecessary stencil cleaning and
paste dispensing operations. To achieve this, the system inspects various areas
of the board and/or stencil to detect the following:
Inspection Type Description
Paste on Pad Basic Amount of the pad covered by solder paste, as a % of the
aperture size
Stencil Blockage Basic Solder paste remaining inside stencil apertures
Alignment Advanced Accuracy of paste positioning compared to the learnt pad
Bridging Advanced Distance between adjacent deposits of paste
Volume Advanced Volume of paste on the board
Stencil Smear Advanced Solder paste on the stencil
NOTE: Advanced Inspection Type option is not available on some machines.
