Instruction Manual

Advanced Programming 9-5
Advanced Underfill Workpiece
In these exercises, you will learn how to program an entire underfill workpiece. The first exercise will be
the L-shaped pattern. The second exercise will be the U-shaped multipass pattern. You will learn when to
insert timer commands, height sense commands, flow rate measurements, use skip marks and re-use
fiducials.
Estimated time to complete: 60 minutes
For the exercise below, you will use Side 2 of the Tutorial Board. You are building a dispensing program
to dispense an L-shaped underfill line on four flip chip models on the workpiece. On a second pass, the
program will dispense another L-shaped “seal” pass line along the opposite edge over the same flip chip
models. To do this, you will perform the following:
• Define the Tutorial Board Side 2 as the Workpiece with 2 fiducials in the opposite
corners and a skip mark.
• Create an L-shaped pattern called “
Lfill” which will consist of the two L-shaped lines,
Line 1 and Line 2.
• Define the origin of
Lfill.
• Define a fiducial for
Lfill.
• Define a skip mark for
Lfill.
• Teach the first L-shaped, Line1, in
Lfill.
• Teach the second L-shaped, Line 2, in
Lfill.
• Place the pattern
Lfill on the workpiece at three other locations.
• Save the program as
undrfil.fmw.
• Perform a dry run.
• Perform a wet run.
?NOTE If you are performing this tutorial during a new programming session, be sure to
review the Setup and Configuration section of this manual.
For the following exercise, you will need to use an underfill epoxy, such as Hysol 4510 and a #20 gauge
¼-inch needle.
