Abstract

This article documents the process used to create images from a list of parts for displaying by an application program. These images can be in any format required by the using system (ie. Bitmap, Video, Graphical, etc.) or for any platform (ie. PC, PS/2*, AS/400*). The current application for which this system was developed uses graphical images for display on a PS/2.

Card Image Creation for PS/2 Draft Copy

       This article documents the process used to create images
from a list of parts for displaying by an application program.  These
images can be in any format required by the using system (ie. Bitmap,
Video, Graphical, etc.) or for any platform (ie. PC, PS/2*, AS/400*).
The current application for which this system was developed uses
graphical images for display on a PS/2.

      This process was developed in conjunction with the development
of a totally new data collection system in CPPC (Circuit Packaging
Production Center).  It is a "stand-alone" function which resolves
the problem of image creation for a card repair application.  Even
though this process is for the Repair function of the overall system,
it can be used independent from this system for any application which
needs to build an image from a bill of material.

      In electrical card production, the collection of defect
information is critical to predicting and identifying problems early
in the process.  This reduces scrap, shortens the cycle time of
production, and, hence, the cost of the cards is lowered.  The
accuracy and instantaneous availability of this information is
essential.  A new system is currently being used which simplifies the
operator input and increases both the reliability and availability of
defect information.

      This new system displays an image of the card to the operator
making it easier to indicate the defects to the system and instantly
captures accurate repair information. These images are continually
changing and new cards are always being released.

      Creating the image is not a problem.  Many tools exist to
produce graphical and video images of objects.  The problem arises
from creating new and updated images on a timely basis as the cards
change.  As new cards are released and Engineering Changes (EC) are
applied to existing cards, there needs to be a way to produce new
images automatically before the cards reach the manufacturing area.
This method is the subject of this disclosure.

      A solution to this problem is two fold.  First, a library of
component images for each SHAPE used in a card manufacturing area,
including raw card images, is built. These images are stored on a
disk as "bit images" in the proper format to easily display them on a
terminal.  Using the shape reduces the number of images needed to
display all cards.  The card area uses several thousand part numbers,
but only about a hundred shapes.  For example, there are many
resistors which have various part numbers and various values.  Each
is a totally different part, but on the image of the card, there is
no difference in appearance.

      Secondly, output from the design phase is used to merge the
component images and form a complete image of the card. A list
containing each part number, its SHAPE, location, and orientation is
currently being produced during design for an existing...
