4 Heater Controls Overview The heater controls are used to setup and regulate the system heaters, needle heaters, fluid cooling and temperature sensing devices. This chapter explores the heater control user interface and teaches you how to set up the configurable options. Most settings are set at the Asymtek factory at the time of shipment and usually do not need to be changed.
This window is used as a quick-check for viewing Set Points (SP) and Present Value, also referred to as Process Variable (PV). Later in this chapter, you will learn how to set these options. Figure 4-1 Next, use the mouse or trackball to highlight loop one and double-click on the loop name.
Each loop has a dialog box which shows its settings under the Main tab. Figure 4-2 shows the Loop Parameters dialog box. On the Main tab, you set the temperature with Set Point (SP). The Output Value is the percentage of the total capacity of the heater being used to achieve or maintain the Set Point. Auto Mode regulates the loop temperature automatically. Manual Mode disables the automatic temperature controller and allows you to regulate loop temperature using the Output Value.
Figure 4-3 The Run Time tab, shown in Figure 4-3, shows the parameters for configuring heater behavior during production runs. The heaters can be turned off or turned down during fiducial searches. The heaters can also be turned off if the dispensing system does not receive a board or sits idle for a specified amount of time. Heater temperature can also be verified before dispensing begins. Select the Heat Control tab.
Figure 4-4 The Heat Control tab, shown in Figure 4-4, shows control parameters that are used to define the heating process for your specific system. All values in this dialog box should be set at the Asymtek factory prior to shipping and should not be changed by the user. For more information, consult the Anafaze User’s Guide. Next, select the Input tab.
Figure 4-5 The Input tab in Figure 4-5 is used to define the input types for each loop. Unused loops which do not have heaters attached are defined as “skipped”. Also, any process offsets to make up for signal inaccuracy are set here. All settings in this dialog box are set for each loop in your system at the Asymtek factory prior to shipping. Input Reading Offset can be used to make up for a calibration offset.
Figure 4-6 Figure 4-6 shows the Output tab which is used to define the type of output the controller uses for the heating process and specific parameters for the output type. All settings in this dialog box are set for each loop in your system at the Asymtek factory prior to shipping. The Type of output used most often for the dispensing system heaters is Time Proportioning (TP). In this Type, the percent output is converted to a percent duty cycle on the programmed cycle time.
Figure 4-7 The Alarm tab, shown in Figure 4-7, is used to setup the process alarms. An alarm can be set for each loop. The alarms notify the user of changes and deviations from the temperature Set Point. Process alarms can be set to notify the operator and/or control the output in the event of deviations from the Set Point. There are four alarm types: High Process, Low Process, High Deviation and Low Deviation. Figure 4-8 shows the activation and deactivation points.

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.
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, vision processor board and video mixer 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.

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.
14. Using the Position Controls, move the dispensing head to the lower left-hand corner (LLHC) of the tutorial board and center the crosshairs on the dot in the LLHC. 15. Click on Teach. 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 smaller white-lined box in the video display window.
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.
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 corner of 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 transfer process.
1 2 3 4 Item 1 2 3 4 Description Search Length Projection Length Caliper Application Point Figure 7 -4 1 Item 1 Description 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.
? 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. > 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 “Teach pattern origin.” 5.
13. Adjust the Search Length and Projection Length to experiment with their effect. TIP The Search Length should be optimized so that it contains only one gray value transition (light to dark, or dark to light). A longer caliper increases the range for finding the corner, but also increases the chance of finding the wrong corner. TIP 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.
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 and does not need to be performed 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.
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.
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: 1 LINE: 1, Start: (X1,Y1), End: (X2,Y2) 2 END: > X1,Y1 are the coordinates for the starting point of the line. X2,Y2 are the coordinates for the end point of the line. 15. Repeat Steps 8 through 14 to program the next two lines below the first line on the Tutorial Board.
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. 2. Click on 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 can customize certain line parameters for 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.
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 Length This is the horizontal distance that the dispensing head moves back over the dispensed line after raising up the Backtrack Gap distance. This encourages congealed fluids to detach and distributes any excess fluid back across the line. The units are inches. Typically, 30 - 40 mils (0.030 - 0.040 in) is sufficient. Backtrack Speed This is the speed that the dispensing head travels when moving along the Backtrack Length. The units are inches/second. Typically, 2 in/sec is sufficient.
To program weight control lines: 1. Perform the Programming Setup procedure in the Setup and Configuration section of this manual, then return here. > Load Side 1 of the Tutorial Board. > When you create the Workpiece, define the Workpiece Alignment. > Choose No Fiducials. 2. Click on Dispensing Elements on the Program Commands toolbar. > A Teach Window opens. 3. Click on Weight Control Lines.

Click on Done. > A message box opens, indicating the calculated line speed for the newly created weight control line. 10. Click on OK.
23. Click on Done. > A message box opens, indicating the calculated line speed for the newly created weight control line. 24. Click on OK. 25. In the Programming Window, select Edit Line Parameters from the Edit menu to open the Line Parameters dialog box. 26. Set the Line Parameters for Line Type 1 to: Pre-Move Delay Factor: 0.1 Down Speed: 2 Down Acceleration: 300 Dispense Gap: 0.015 Speed: (not used for weight control lines) Shut-off Distance: 0.010 Suckback: 0.000 Dwell: 0.0 Backtrack Gap: 0.
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 procedure in the Setup and Configuration section of this manual, then return here. > Load Side 1 of the Tutorial Board. > When you create the Workpiece, define the Workpiece Alignment. > Choose No Fiducials. 2.

Select Wet Run from the Run menu. > Watch to see the dots dispensed.
Arcs There are two available methods for teaching an arc: • Start, Middle, End (S,M,E) • Center 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.

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. > The dispensing head will move after your response. > Watch to see the camera move across the rectangular pattern.

Select Wet Run from the Run menu. > Watch as the pattern is dispensed in both locations. > Examine the board for quality and accuracy. This concludes the tutorial on Placing Patterns.
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.
Skip and Prompt can be used for production runs. Occasionally chips are placed skewed on a workpiece or a defect interferes with a fiducial. In this case, if Skip is chosen, the program will automatically skip the fiducial or part it is searching for and continue with the next step in the program. If Prompt is selected, the Operator is asked to either re-teach the unfound location, or skip it and continue the run.
