Introduction: Ultimate 100-lll Laser Airborne Particle Counter

General Description and Purpose of the ToolThis device is used to monitor the air velocity and concentration of particles in

the cleanroom. The monitoring procedure is performed weekly at various sites in the cleanroom in order to provide statistics on the changes in air quality and to alert the area to any possible damaging levels of contaminants. At each testing site, the Ultimate 100 is programmed to take in one-tenth of a cubic foot of air per sampling, and to repeat the sampling at specific intervals until the required number of samples is collected. Sampling parameters include not only the volume of air required per sample, but also the class of the cleanroom to be monitored, the temperature, the relative humidity and the date and time of the sample. Results of the sampling are both displayed as the data is gathered and recorded on disk. The results are later posted to a weekly monitoring report in Process Control. If the air quality becomes out of control in any way or at any particular location, the irregularities are reported immediately so that steps can be taken to bring the readings back into an acceptable range.

A device called the Alnor CompuFlow Model 8525 Multipurpose Meter performs a similar function. It records the air speed being generated by the venting systems in the cleanroom (laminar air flow). Laminar air flow helps to move contaminating particles directly out of the air and into the filters where particles are trapped. Air speed monitoring is done weekly as the same locations and times as the particle monitoring. Samples are taken manually at each test site by holding the by holding the Alnor’s probe in the air current to be measured. Readings are taken, and repeated if necessary, according to the monitoring instructions for each test site. Results are posted on the weekly monitoring report, but air velocities that fall outside acc3ptable limits ate reported immediately to the appropriate departments so that the condition can be corrected.

Safety Considerations:

Ultimate 100 When plugging in or unplugging the unit, the battery must be connected to avoid

damaging the machine. The operator must know how to remove and replace the battery compartment door safely.

Only a maintenance PA can change the battery on fuses. Only a qualified technician should open any door or compartment on the unit. Exposure

to the laser can result in injury as well as damage the machine.

Alnor Compuflow Only a maintenance PA can change the battery The probe should be extended only as far as necessary to get a valid reading and should

be compressed when the unit is being transported.

General Safety Observe any special safety precautions prescribed for a given test site. Be aware of alarms and emergency situations that affect as test site. Know where to find and how to use safety equipment such as respirators, eye baths,

emergency showers etc. Know how to get assistance in an emergency situation.

Environmental Considerations:

Operators must follow the procedures for gowning and cleanroom protocol as describe in SIWF858520 “OR-1 Procedures: Gowning, Protocol and Cleanroom Regulations”.

Equipment taken into the cleanroom must be properly decontaminated. No paper documents are allowed into OR-2.




When performing air monitoring tests, only the exact materials and equipment named n the document may be used.

Before setting up to do any monitoring, inform the operating supervisor of the time and locations of the tests.

When the particle counters are in place for a test, the light sources and exhaust fans must be directed away from any product or process equipment.

If the unit is outside the cleanroom, any testing that may cause the pump to turn on could cause contamination to build up inside the unit. A small HEPA filter which fits in the sampling outlet is available to prevent this problem.

Information about the cleanroom environment and the general procedures for working in a cleanroom can be found in GIEE96020 “Environmental Management Requirements for Manufacturing and Manufacturing Maintenance Operations.”

Terminology:

Bay: Also known as a clean aisle. A Bay is a confined cleanroom work area that contains equipment used for one or more steps in a manufacturing process. This is the area in which cleanroom operators are located. Airflow in a bay is from ceiling to floor.

Chase: The chase is the cleanroom area between two bays in which chemicals, power, air and other facility items are placed in order to support work being done in the bays. Airflow in the chase is from floor to ceiling.

Class 1 Cleanroom: A cleanroom in which, according to Federal Standard 209E, the maximum number of particles per cubic foot of air cannot

exceed the limits on the following chart.

Class 1 Cleanroom StandardsParticle Size in Microns (µ) 0.1 0.2 0.3 0.5

Max # Allowed per cubic Foot 35 7.5 3 1




Class 10 Cleanroom: A cleanroom in which, according to Federal Standard 20E, the maximum number of particles per cubic foot of air cannot exceed the limits on the following chart.


Max # Allowed per cubic Foot 350 75 30 10

FPM: Feet per minute; a measurement used to define laminar air velocity in terms of the amount of straight air flow past a given point in one minute.

Histogram: A diagram, chart or other pictorial method of illustrating the changes in a given variable over a span of time.

HVAC: An acronym for High Vacuum. It refers to the equipment, processes and checks used in the air recirculation systems in the cleanroom.

Laminar Air flow: The straight and direct air flow (up or down) generated by the air recirculating systems in a cleanroom. In OR-2 the acceptable range for laminar air flow is 60-120 fpm (feet per minute), and the average rate is 75 fpm.

The Ultimate 100-lll Laser Airborne Particle CounterThis unit is used to collect air samples to monitor the particle content of air in the clean room spaces.

Note: The ultimate 100 is generally stored in Chase 14. There is an AC outlet in the chase used for recharging the unit. The unit can be plugged in between monitoring sessions to keep the battery at full charge. No lockout or tagout procedure is necessary for this device.

Task Number Task2.1 Power on the Device

Procedure:Check the AC cord to ensure that it is unplugged before turning the unit on or attempting to move it. Do not let the cord drag when moving the cart. Store it in the bin under the cart.

Figure 2: Main Screen Detail

Regulate the screen contrast using the VIEW ADJUST buttons to the right of the screen display

Check the CHARGE = field on the main screen which shows the approximate operating time left before the battery fails

Check the LP (Laser Power) = field for the % of maximum power still remaining in the laser component.




Task Number Task2.2 Recognize low battery warning and perform a shutdown

Procedure:Low Battery Warning can take one of two forms:

When the “CHARGE =” field is 0.5HR, the remaining operating time may be from 15 to 45 minutes. When that time has elapsed:

The pump will not turn on The settings and stored data will be preserved

When the “LO BATTERY HALT” indicator is on the screen: The battery is fully depleted The main screen is blank Only the POWER button will operate Setting will be preserved and the data already on the disk can be retrieved. If the

power halted during a sample, that data will be lost.In either warning situation, the unit should be turned off and recharged. See Task 2.4 for recharging procedures.

Task Number Task2.3 Recognize low laser power and take appropriate steps

Procedure: When the ultimate 100 is working properly, the laser power should be close to 100%. Laser power readings below 80% must be corrected by a qualified technician. DO NOT try to assess the laser problem by opening the access door. (See Figure #3). Injury and machine damage can be the result.

Changes in the laser power can reflect on e of three possible problems: The laser is dirty and needs to be accessed for cleaning. The unit needs recalibration to correct the readings. The laser is actually failing.

No matter what the cause may be, call maintenance for assistance before using the machine again.




Task Number Task2.4 Check and charge the battery

NOTE: The Ultimate 100 has a rechargeable sealed lead battery which may, occasionally, need replacement. This task is performed by a maintenance PA. Inspect the battery ONLY if the unit’s power and indicator lights are not functioning.



Battery Door

Access Door


Figure 3 – Back View of the Ultimate 100

Procedure:To inspect the battery:

Check to be sure that the unit has been unplugged. Remove the power cord and store it in the cart bin. Using a flat head screwdriver, turn each of the three battery door screws ¼ turn

counterclockwise. Remove the battery door, taking care to keep the screws from falling out and

getting lost. Check to be sure that the battery wires are properly connected. They should be:

Secure on the terminals Connected RED to RED and BLACK to BLACK

Do not turn on the unit if the wires are not properly connected. Reversing polarity will short out the 12 Volt fuse and may damage the unit. Call maintenance if there is a problem with the wiring.

After checking the wire connections, re-attach the battery compartment door by replacing the slotted screws and turning them ¼ turn clockwise to tighten them again.

If a low battery warning has occurred: Use the adapter to plug the unit into an AC outlet. Turn on the unit using the Power button. Verify that the CHARGER ON indicator is lit.

READY light on means that the battery is fully charged. CHARGING light means that the battery is not fully charged.

The indicator light will change to READY when the charging is complete. Fully charged, the unit will operate for approximately 6 hours.

Task Number Task2.5 Select and modify variables on the main display screen

Procedure:On the main screen there are:

Six particle modes defined by particle size ranging from .10 to 1.0 microns. These are: 10, .15, .20, .30, .50, 1.0




Five menu choices :START turns the unit on and offPRINTR turns the printer on and off so that the data visible on the main screen can be printedDSPLY changes the manner in which data is displayed on the screen. Use the SELECT command to select a variable and MODIFY to change it. Under DSPLY choices include:

Large or small numbersData expressed in numbers or in histogram

The unit will select the data you request. You may use the following means of selection.

Total Count: Particles are counted in each category they fit, For example, a .25 µ particle will count once in the >.10 category, once in the >.15 category and once in the >.20 category. This arrangement allows for an accumulated total of particles that fit into each of the lower level categories. The total number of all particles in the sample will be represented in the .10 category.

DIFF COUNT: Particles are counted only in the highest category for which they qualify. For example, the 25 µ would be counted only once in the .20 category since it is bigger than the .15 particles but smaller than the .30 particles.

Count/CF(M): Output of the sample can be expressed wither as a ratio of particles to cubic feet or cubic meters of air sampled.

ID shows the sampling locations already stored in the unit. Functions at the ID level include: Selecting an existing sampling location. To select, scroll up and down using the

arrow keys to find the appropriate site designation. Adding a new location. Adding should only be done with the approval of a

supervisor or manager. To all a location:Select NEWKey in the new IDSelect ENTER




Deleting all locations. Deleting must be done with extreme caution and only upon management approval.

Use SELECT to highlight the field to be changed. Tab through fields that are already correct by pressing the SELECT key twice. Use MODIFY to scroll up and down within a field to select the correct value. When all fields are correct, press EXIT.

Task Number Task2.7 Locate and set up testing on required sites

Procedure:

General Information:Sampling must be done in each of the required areas weekly. The results of the testing must be entered through Process Control whenever a set of samples is completed.

The Ultimate 100 is mounted on a cart that is rolled from site to site. If the cart has been outside of the cleanroom, it must be wiped down prior to entering. Observe full gowning protocol when entering the cleanroom.

The number of sampling locations is based upon the square footage of the room being monitored. Currently the breakdown for the number of sampling sites is as follows:




LOCATION # Of Sampling SitesBays 1-14 4 in eachChases 1-4 3 in eachMain Aisle 7Laser Scribe 3Gowning Vestibule 6Decontamination 2Staff Room 2Bay 15 8Photolithography Bay 16 8Photolithography Bay 17 9Photolithography Bay 18 9

The sampling sites are divided into 4 groups for implementation purposes. Each with 38 sites requiring readings. Details of the sites, locations and codes for these groups are listed on the Shift Particles Assignment Report. A sample of this monthly report for Group C shows how the different areas appear on the report.

NOTE: IF the device is stopped accidentally before a sample is complete, the data for that sample will NOT be stored in memory.

Procedure: Press START to start the pump and begin the initial delay time. (The display should now

read STOP. When DELAY = 0 is reached on the main screen, the device will begin to count particles. When counting starts, ET= will appear on the screen. ET stands for “elapsed time”. This

indicates that a sample is in progress. When that sample is completed the display will add DELAY = and the next delay

countdown will begin. The cycle looks like this:

DELAY= 0 ET= 0 DELAY=

This Delay/ET cycle will continue until the number if samples taken equals the The number of samples in the program parameter. In the standard disk program that number is 3.

When the last sample is complete, the counter will beep four times and the pump will turn off automatically. When the machine shuts down in this way, the data from the samples will be stored for later retrieval.

When samples are complete, the unit may be moved to the next site.
