INSTALLATION QUALIFICATION PROCEDURE
The goal of the installation qualification is to test if the installation process has inadvertently affected the normal operation of the laser bonder’s hardware.
1. Test for start up sequence: Turn on the main power switch on the rear left side wall. Watch the following activities take place:
a. The LCD screen on the front control panel lights up. The LCD displays a “Welcome…” message for about 3 seconds and then displays the status screen.
b. The laser head will move to its left limit position , stop, and set the current position as the home position (Zero).
The above start up sequence takes place every time the main power switch is on. A successful pass of this step indicates that installation did not cause any problem in the start up sequence.
2. Test for process monitoring system: Turn on the power switch on the monitor and wait for about one minute. The monitor should illuminate and show the left spindle image. If not check if power is plugged into the camera power jacket and ensure that the RCA type cable is inserted fully into the yellow video receptacle behind the removable panel of the monitor. Record any abnormal observation. Successful pass of this step indicates that the process monitoring system is normal.
3. Test for laser unit: Turn on the power key switch on the laser unit (See Figure 5). The Power On LED (yellow) on the rear panel of the laser unit will turn on. All Laser On, Laser hot, and Laser Fault LED lights should be off. Successful pass of this step indicates that the laser unit works normally.
4. Test for beam delivery system: Turn on the Diode Laser switch (Figure 6). Hold a piece of white paper close to the center of the spindle. A red spot should be seen. Rotate the collimator. The size of the red spot should change accordingly. Successful pass of this step indicates that the laser beam delivery system works normally.
5. Test for spindles: Push and hold the SPINDLE JOG button on the control panel (see Figure 4). The left and right spindles inside the work chamber (see Figure 8) should start to rotate. Watch the speed on the LCD screen. Release the SPINDLE JOG button. The spindle should stop immediately. Successful pass of this step indicates that the spindles are normal.
6. Test for laser system motion: Turn the LEFT LASER JOG or RIGHT LASER JOG switch on the control panel. The entire laser unit should move to the left or right accordingly. Return the LEFT or RIGHT switch to the center position, this should stop the laser unit movement immediately. Turn the Laser Jog switch to the RIGHT and let the laser move to the far right. The laser unit should stop prior to the right spindle motor. This is the right limit position of the laser unit. The laser will not be able to move beyond the right limit. NOTE: by moving the right spindle the right limit changes as well to prevent damage to the beam delivery system. Successful pass of this step indicates that the laser unit motion system is normal.
7. Test for laser alignment: Install the 0.039” catheter adapter into both the left and right spindles. Insert a mandrel (about 0.031” diameter) into the adapter and release the appropriate collet button so that the mandrel is securely held. JOG the spindle and make sure the mandrel rotates without wobbling. Otherwise check if the mandrel is well centered. Move the laser unit to point the laser at the mandrel. If the red diode laser spot could not be seen, check if the diode laser pointer switch is on. If not, turn it on. A red laser spot should be seen on the mandrel surface (the diode laser spot on the monitor should be slightly off center and on the lower side). Manually move the laser unit to the left or right. The red laser spot should stay at the center of the mandrel. If not, first check if the mandrel is well centered. If the problem persists, laser alignment may be necessary (see Troubleshooting section). Successful pass of this step indicates that the laser system and spindles are in alignment.
8. CONGRATUATIONS! The IQ is completed.
