11-18 3D X-Ray Inspection Methodology
The current sequence of each 3D site is represented by the number inside the site. To change the
order of the whole list, the user can begin with sequence # 1, one single click within the range of
any 3D site will make that site No. 1 and the order of the rest will be pushed back by 1. The next
3D site being clicked will be site No. 2. Each click of 3D site will automatically increase the seq.
# by 1, which represents the current 3D site. In this way the user can re sequence the whole 3D
site list and change the order of 3D inspection. If the user only wants to change certain sites’
order and not all of them, all he needs to do is to enter the number in the box and click Enter to
let software remember and then click on that 3D site which will be run in that specific order.
Future Sites… is useful for offline programming or online programming. Click the Future
Sites… menu item will launch the 3D Future Site dialog.
3D X-Ray Inspection Methodology 11-19
All functions related to future site are included in this dialog box. The Add Site, Move to Next
and Delete Site are used to add a future site, navigate to next future site and delete a future site in
current location. The “Capture Image Set” function will allow user to capture image set for
future site only. After that all future sites will change to normal 3D sites and all red crosses
(which represents the location of future sites) inside map view window will change to white
circles automatically. The Show 3D Site in Video View checkbox if checked will display the
inspection area of all sites (normal and future) in video view. The feature is useful during recipe
debug when the software complains about certain 3D inspection boxes are not included in any
3D site.
Add Laser Reference … function provides user a quick and easy way to allocate laser
references on board surface, instead of train laser references as regular parts. To start user needs
to execute this function and launch the Add Laser Ht Reference… dialog.
To add a laser site, all user needs to do is to move the stage to the desired location and click the
Add button. The laser reference will be added to the list automatically. It is advisable to test the
laser and adjust the position after adding the laser reference sites. The user can keep adding laser
sites by clicking the Add button. Clicking the Close button will dismiss the dialog.
Profile Board Height when clicked will launch the following Profile Board Height Dialog.
There are two options available. The first option “Set 3D Site’s Surface Offset Based on the
Measured Height Value” when selected will run all available laser references measurement
once and update the board offset number as well as the surface height, pitch and roll information
for each 3D site. The second option “Repeat 10 times and Report Worse Case Measurement
Repeatability” when selected will run all available references 10 times and calculate statistics
for each reference. When finish the test another dialog box will show up and report the IDs of
laser references which have the best and worst statistics. If the worst statistics doesn’t look good,
it is advisable to go back to that particular location and fine tune laser reference setup parameters
or even re-adjust the position of that laser reference site. The second option is mostly used for
diagnosis and recipe program debugging purpose.
Re Sequence Laser Ref. by default during inspection the software executes the laser reference
in the sequence that it was created. This menu selection allows user to adjust this sequence. This
is an interactive feature very similar to the Re Sequence Sites feature discussed above.

Save Height Info. to File when executed will save the measurement results of every laser
references together with the related info, e.g., X/Y location, ref ID, etc… to ZMap.txt file under
current recipe folder.
Show Only Current Site IBs is a display flag user can toggle on or off. Turn it on if you want to
find out which inspection box (IB) is inspected in which site.
Inspect 3D in Dry Mode, 3D inspection is generally slow, complex boards can take many
minutes to inspect. During inspection recipe fine tuning it may need to inspect the same board
many times to determine the optimal inspection parameters. The Dry mode speed up the process
by skipping the image capturing steps; without image capturing 3D inspection is about the same
speed as the 2D inspection. User can use dry mode only when the same board is inspected
repeatedly and when there is no change to X-ray power levels.
Capture IS for Offline Program (Capture Inspection Path Image Set for Offline Programming).
This feature capture an Inspection path Image Set (as oppose to Grid Image Set) before 3D
inspection boxes are defined. This is important because it allows the time consuming portion of
the recipe development process, defining 3D inspection parameters, set 3D site offset, etc to be
done offline line without consuming machine time.
11.7 Advance 3D Options
Click the Advance 3D Options in the menu above will launch the Advance 3D Control dialog,
as showing below. These are really advanced options and should be operated by person with
deep understanding of 3D X-Ray only.
Move Detector: Clicking the arrow button once will move the position of X-Ray detector to that
direction with amount specified in open field. This function is used for diagnostic and calibration
purpose by factory engineer only.
