7 Programming Basics Overview This chapter introduces the fundamentals of developing dispensing programs in FmNT. These skills prepare you for more complex programming in the next two chapters. It is essential to be familiar with the tools you will use to program, such as the Vision System software. This chapter explains the use of Model Fiducial Finder and Corner Finder in the Vision System. You will be taught basic tips on how to define and recognize good fiducials and how to set up for edge detection.
For example, the first level of a multipass underfill program might look like this in FmNT: The first line of the program is a Purge command. The dispensing head will move to the Purge Station and purge the valve for two seconds. The second command and the 11th command form a multipass loop, which means that commands 3-10 will execute in order a defined number of times, in this case twice, as defined in line 2.
Building a Program in FmNT It is important to learn how to build programs in FmNT. Complex multipass dispensing programs are built by first defining patterns, then adding those patterns to the whole workpiece. When building programs, it is important to keep in mind that you want to develop the fastest method of dispensing in order to maximize production throughput. You gain this efficiency by constructing the patterns and adding them to the program in the most time-effective manner.
Look at the following program instructions in Figure 7 -1. Specific pattern program lines are displayed separately. Only the instructions for the currently selected pattern are displayed in the programming screen. The currently selected pattern is indicated in the Pattern Name text box. As shown, the currently selected pattern is Workpiece. The instructions for Workpiece shown in the programming screen are function calls to a sub-pattern called “chip 1.
The Vision System An essential component of the programming and production process of fluid dispensing is the Vision System. The Vision System is capable of automatically locating features on the workpiece so that patterns can be placed accurately. The Vision System hardware consists of a camera, light source, CognexÒ Vision Processor and video board.
Fiducial Detection The Vision System has three tools or methods to find fiducials as described below. The exercises that follow will teach you how to use these tools. The first exercise will use the Model Finder method to define Workpiece fiducials. The second exercise will use the Corner Finder method to define a pattern fiducial. Defining Workpiece and pattern fiducials is the crucial first step to creating accurate dispensing programs.
Table 7 -1 Shape Fiducial Ratings Characteristics £ donut Excellent. Immune to rotation. Inner and outer diameters allow for further definition. # pound Good. Uniqueness maintained under rotations. l circle Good. Immune to rotations. ❍ hole/gap Poor. Requires machining accuracy to match definition. Not repeatable between different workpieces. : cross Poor. Single axis identification does not allow for poor quality printing of the shape.

To teach a model fiducial: 1. In the Main Window, click on Teach a Program. 2. Load the Tutorial Board (Side 1) as follows, depending on the type of material handling option your system has: A. For systems equipped with conveyors, set the Tutorial Board (Side 1) at the mouth of the conveyor. Use the dispensing system Conveyor Controls to set the proper width. Choose Manual Load Board from the Setup menu or click on the Load Board icon. > The board will be loaded into the dispensing area.
16. Click on Done. > Now you are asked to select the method for defining the first fiducial. > Notice the choices for fiducial finding offered below the video display window. 17. Select the Model Finder method. 18. Click on Next. > Notice the white-lined box in the video display window. This is the Model Window, the area which will be defined as the fiducial. > For our first fiducial, we are going to use the same dot we used to define the workpiece origin. 19.
23. Click on the Run Time tab. > “Check for location tolerances” means that FmNT will check the found location of the fiducial and compare it to the location where it expected to find it. If the difference between the two locations is greater than the Location Tolerance, FmNT will consider the fiducial to be “Not Found.” This ensures that an incorrect fiducial or other feature is not considered to be a correct fiducial, and prevents dispensing on parts that are too far away from their expected locations.
31. Using the Position Controls, move the dispensing head to the upper right-hand corner (URHC) of the tutorial board, center the crosshairs on the dot in the URHC, and repeat Steps 20–28 to teach the second fiducial. > Once you have completed teaching the second fiducial, you will have successfully taught the Workpiece fiducials. 32. Continue to the next section and use Corner Finder to teach the pattern fiducials. This concludes the tutorial on Model Fiducials.
Corner Fiducials Corner Finder is an alternate method provided by the Asymtek Vision System to identify fiducials that are part edges or lines or edge pairs, such as the edge of a die. In some cases accuracy is greatly improved by identifying the part to be dispensed on as a fiducial. The position of parts can be slightly rotated by automatic placement systems, or the parts can be dislodged during the solder reflow process.
Read the TIP section “Light Level” below. TIP Light Level The Light Level controls brightness of the LED or fiber optic lights directly. The vision system can have one or two light sources. For finding the corner of a die on a board, one light source may be better at casting the proper shadow onto the board and producing the high contrast which is most easily recognized by the Vision System. On M-600 Series dispensing systems, Light Level can be varied from 0 - 15.
Search Length Projection Length Caliper Application Point Figure 7 -4 Multiple Calipers Figure 7 -5 When using a single fiducial with Orthogonality Tolerance, FmNT calculates the angle of the corner defined by the calipers. If the corner is within the Orthogonality Tolerance, the part is considered square and dispensing on the part will be performed. For example, if the Orthogonality Tolerance is set at 5, and the corner fiducial is determined to be 85-95 degrees, FmNT considers the part to be square.
? NOTE You should first perform the preceding tutorial on Model Fiducials before performing the following exercise. To use Corner Finder to locate an edge: 1. In the Programming Window, click on Pattern on the Program Commands toolbar. 2. Select Create Pattern. Pattern > The Create Pattern dialog box opens. 3. Type Sample in the text box and choose One fiducial. 4. Click on OK. > A Teach Window opens asking you to define the pattern origin. 5.
TIP Caliper Sizing The Search Length should be optimized so that it contains only one gray value transition (light to dark, dark to light). A longer Caliper increases the range for finding the corner, but also increases the chances for finding the wrong corner. Projection Length controls the averaging for the transition amplification. A wider Caliper is better for rough edges or eliminating noise caused by traces on the board. Thinner calipers are more immune to rotated parts.
Editing Fiducials You can edit fiducials defined for your workpiece at any time. You may want to edit fiducials if the system fails to find too many of them during production runs. The procedure below is a reference procedure. Do not perform it now. To edit fiducials: Using Model Finder 1. Load the workpiece board. 2. In the Programming Window, make sure that the name of the pattern containing the fiducials you wish to edit appears in the Pattern Name text box. 3.
8 Beginning Programming Overview This chapter introduces you to the fundamental dispensing commands and patterns that form the foundation of all dispensing applications. You will learn how to create basic dispensing patterns. Later in this chapter, you will learn how to place those patterns at multiple locations on the same workpiece. It is essential for you to develop the basic programming skills in this chapter. These skills will be further developed in the next chapter, “Advanced Programming”.
Lines Lines are a common dispensing element for flip chip underfill applications. Weight control lines, which are lines whose fluid weight can be user-defined, are often used in underfill applications. In this exercise, you will learn how to program and dispense simple lines. Afterwards you will learn how to edit the lines. Weight control lines are treated separately in the next section. Estimated time to complete: 45 minutes.
10. Use the Position Controls to move the crosshairs to the starting point of the first line in the upper left-hand corner (ULHC) on the Tutorial Board. 11. Click on Teach. 12. Use the Position Controls to move the crosshairs to the endpoint of the line. 13. Click on Teach. 14. Click on Done. > In the Program Window, you should see the following: X1,Y1 Coordinates of Line 1 Start Point 1 Line 1, Start:(12.264, 10.896), End:(13.290, 10.
16. In the Programming Window, click on Run and select Dry Run. Run The dispensing head will move after your response. > Watch the video display as the dispensing head performs the programmed commands. The camera will act as the needle and follow the lines, but no dispensing will be performed. If the lines were “dry dispensed” at an incorrect angle, you may need to reprogram the origin of the board and workpiece angle. Unfortunately, this means you will need to start over defining this program. 17.
Editing the Lines If you were not satisfied with the lines dispensed, you can simply edit them. This exercise will teach you how to edit existing lines in a program. For this exercise, you will shift the lines over and shorten them. To edit the lines (shift them over and shorten): 1. From the Edit menu in the Programming Window, select Edit Pattern. Pattern 2. Click on Workpiece. Workpiece The dispensing head will move after your response. 3. Place the cursor on 1 LINE in the program and double-click.
Weight Control Lines Most lines for flip chip underfill applications are weight control lines. These are lines where the programmer has greater control over specific characteristics of the line. A defined amount (weight) of fluid is dispensed over a defined length of line or pattern. Estimated time to complete: 45 minutes. To view the customizable parameters for weight control lines: 1. In the Programming Window, click on Edit and select Edit Line Parameters. Parameters > 2.
Pre-Move Delay Factor Some fluids have a high viscosity which means that they do not dispense as quickly as lower viscosity fluids. The Pre-Move Delay Factor increases the time that the dispensing head is parked with the valve ON, prior to a programmed move. The delay at the beginning position insures that a full line is dispensed. The units are seconds. Typically, 50 ms (0.050 sec) is sufficient for most underfill fluids. Down Speed The Down Speed is how fast the dispensing head lowers to dispense.
Backtrack Gap This is the vertical distance that the dispensing head moves up after completion of a move. At the end of a move, the dispensing head raises the Backtrack Gap, then moves the Backtrack Length back over the line that was just dispensed. This encourages congealed fluids to detach and distributes any excess fluid back across the line. The units are inches. Backtrack Gap should be at least double the Dispense Gap.
To program weight control lines: 1. 2. Perform the Programming Setup in Chapter 6 - Setup and Configuration. > Load Side 1 of the Tutorial Board. > When you create the Workpiece, define the Workpiece Alignment. > Choose No Fiducials.

Click on Apply. 28. Click on OK.
Dots FmNT can dispense precision dots as well as lines. Dots are used in surface mount adhesive (SMA) applications. For this exercise, use the valve conditioning fluid. The conditioning fluid more closely simulates the characteristics of SMA fluids. The size of the dots and characteristics of the dispensing are controlled by Dot Parameters in the Edit Dot Parameters. You will learn how to program and dispense dots on the workpiece.
Valve-On Time This parameter controls the time the valve is on while positioned over the dispensing location. The time interval affects dot size. The longer the Valve-On Time, the larger the dot. The units are in seconds. The typical value is 30 ms. However, the Valve-On time can be as long as 6 seconds, depending on the desired dot size and fluid properties. Dispense Gap The Dispense Gap is the distance between the substrate you are dispensing on and the needle tip during dispensing.
Suckback At the end of dispensing a line or a dot, the valve is reversed for the Suckback period to remove any material from the tip of the needle. The Suckback value should be set according to fluid viscosity. Generally, 10 ms (0.010 sec) is sufficient. Mid-Move 1 and Mid-Move 2 These parameters are advanced dot parameters used for special applications and testing. For more information, contact Asymtek Application Engineering.
To program dots: 1. Perform the Programming Setup in Chapter 6 - Setup and Configuration. > Load Side 1 of the Tutorial Board. > When you create the Workpiece, define the Workpiece Alignment. > Choose No Fiducials. Fiducials 2. Click on Dispensing Elements from the Program Commands toolbar. 3. Select Dot from the Dispensing Elements toolbar. 4.
13. For an approximate 30 mil dot, set the Dot Parameters for Type 1 to: Settling Time: Down Speed: Down Acceleration: Valve-On Time: Dispense Gap: Number of Shots: Dwell Time: Retract Distance: Retract Speed: Retract Acceleration: Suckback: 0 2 in/sec 300 in/sec2 0.070 sec 0.015 in 1 0.030 sec 0.250 in 3 in/sec 300 in/sec2 0.000 14. Move the cursor to Type 2 in the Dot Parameters dialog box. 15. Set the Dot Parameter Valve-On Time to 0.250 sec, and Dwell Time to 0.050 sec.
Arcs There are two available methods for teaching an arc, Start, Middle, End (S,M,E) and Center. Refer to Figure 8-4 below. The S,M,E method asks you to teach a starting point for your arc, a middle point, and an end point. The three points are treated like a part of a circle and the arc will be dispensed along the three points accordingly. The Center method asks you to teach a starting point on the arc followed by a center point.
To program an arc: 1. Perform the Programming Setup in Chapter 6 - Setup and Configuration. > Load Side 1 of the Tutorial Board. > When you create the Workpiece, define the Workpiece Alignment. > Choose No Fiducials. Fiducials 2. Click on Dispensing Elements from the Program Commands toolbar. 3. Click on Arc on the Dispensing Elements toolbar. 4. Select the method (S,M,E or Center) for teaching the arc. 5. Use the Position Controls to move the dispensing head to the arc start point. 6. Click on Teach.
Circles There are two available methods for teaching a circle, Start, Middle, End (S,M,E) and Center. The S,M,E method asks you to teach a starting point for your circle, a middle point, and an end point. The three points are treated like points along the circumference of the circle and the circle will be dispensed along the three points accordingly. The Start and End points may be the same point, but it is not necessary to program the circle in that manner.
11. Click on Done. 12. In the Programming Window, select Dry Run from the Run menu. > Watch to see the camera trace the path of the circle. The dispensing head will move after your response. 13. Select Wet Run from the Run menu. > Watch as the circle is dispensed. > Examine the board for quality and accuracy. This concludes the tutorial on Circles.
Area Fill Encapsulation Area Fill dispensing is used to encapsulate a part on a board. It is important for the fluid to cover the part completely without voids. The process by which the fluid is dispensed should be fine-tuned for best results. Area Fills can also be dispensed using Weight Control. In that case, a defined weight of fluid is dispensed in the Area Fill. If Weight Control is not used, the Line Parameters for the selected Line Type are used.
10. Select Dry Run from the Run menu. > Watch to see the camera move across the rectangular pattern. The dispensing head will move after your response. If you get an error message that the speed is too slow, re-check your dot parameters and try again. 11.

9 Advanced Programming Overview This chapter discusses and demonstrates some of the more advanced techniques for perfecting your dispensing programs. You will perform two underfill tutorials, one L-shaped pattern and one U-shaped pattern. You will learn how to increase throughput by using timers and skip marks and reusing fiducials and height sense information. ? NOTE You should complete the preceding chapter, “Beginning Programming” before attempting the tutorials in this chapter.
Re-using Fiducials and Height Sense Information If your workpiece contains many parts, and the pattern to be dispensed is a two or three part pattern such as the L-shaped and U-shaped patterns, checking fiducials and the substrate height during every pass can be time consuming. In many cases, it is unnecessary since the likelihood that the parts could move before the timers expire is very low.
Chip Offset Chip Offset is the distance between the edge of the part (usually a die) and the edge of the dispensing needle. It is defined to ensure that the needle does not chip the die edge during a dispense. The Chip Offset is used in the X-axis and Y-axis as shown in Figure 9-1. A formula is used to calculate the Chip Offset: ½dn + 7 mil = Chip Offset where dn is the outer diameter of the needle. Reticles can also be used to perform the same function as Chip Offset.
Underfill Patterns There are several types of line patterns used for underfill applications. Two common types are L-shaped and U-shaped patterns as shown in Figure 9-2 Variations of these types of underfill patterns are used as well. These patterns and processes are designed to assure complete underfilling without excess and to prevent voids in the underfill.
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.
To program the workpiece with L-shaped underfill patterns: 1. Perform a Programming Setup.
