Advanced Programming 9-5
Advanced Underfill Workpiece
In these exercises, you will learn 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 fiducials 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 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 Chapter 6 - Setup and Configuration.
For the following exercise, you will need to use an underfill epoxy, such as Hysol 4510 and
a #20 gauge 1/4 inch needle.
