Cleaning Methods & Procedures
General cleaning guidelines
It is simple cleaning methods and procedures guidelines. It is suggested that you check the list of permitted and prohibited matters first. For computers related equipment, prepare to take these items to the manager in the cleanroom. If you need LAN access to the cleanroom, please let it know. Before entering a section of the cleanroom, clean the parts with IPA and fiber-free tissue. Complete clear guidance will follow these general guidelines.
Clean the vacuum using common vacuum cleaners for computers, keyboards, etc. Special regard should be given in the ventilation port. These pre-clean clean rooms and volcanoes should work outside and the parts should be covered with clean baggage elements, but not cleaner quality. As an example, notebook computers are favored over desktop computers (though it is not regularly possible) not only due to capacity but also on freshness. Clean all accessories from cleanroom to external location. This tool can then be seized by reducing pollution.
Non-metallic items that are not used in safe with small iron items (screws, bolts, washers) and solutions must be washed using chemical lab located ultrasonic cleaner. After enrolling the Cleanroom Entry Remove from the packaging and apparently visit for any visible marks of pollution that can be re-cleaned when needed. The most reliable way to visually see an item is to see the item page in light of the five-degree angle.
The following works when washing parts using before supplied wipes:
- Fold the half wiping and then close it again half.
- Now apply folding wiper IPA.
- The highest number of jobs per empty should not be maximum four times.
- Remove the surface of a single command.
- Once the four wings have finished, use other folders to clean up the top.
If a person who works hard, goes to a clean room, then a new set of clean gloves should be applied. Then the clean part can be taken to the cleaning room and described within the necessary cleanliness hygiene that is used by Wipers and IPA as described above.
Monitoring of methods and equipment
When producing tools into a clean room, make sure you perceive the following:
All cleanroom owners must be clear that they should consult with the Cleanroom Administrator before clearing any material and methods. This can not be accentuated enough! Monitoring equipment and methods going in a cleanroom is an essential part of cleanroom contamination control. If you bring tools or processes in a cleanroom, follow the specific procedure listed below.
There is no need to buy cleanroom for common tooling such as a screwdriver, nut driver, ruler, vernier calipers because all the cleanroom has fully stocked cleaner tool tools for users’ convenience. The cabinet tooling will not be cleaned as cleanroom use and just cleanroom. Make sure to use the cleanroom tooling when they are returned in the council after using it. Do not give up lying about this because it means other users can not use them. If you are a visitant and need special tools to make sure you contact the Cleanroom Handler to ensure that the tool is accessible.
If you bring a process to the cleanroom, make sure you evaluate the risk of the method and you discuss it with the clean closure manager. Until a discussion with the Cleanroom Handler, no process can be done in a clean manner in a situation, but it is also a monitoring project to control clean monitoring pollution and to help with health and security.
In this article here we show cleaning methods and procedures. Firstly we will talk about cleaning methods then we will talk about cleaning procedures.
Detailed cleaning method
To meet the project pollution hygiene necessities, the bottom support instrumentality (GSE) utilized in clear areas at MSSL for effort tools combination and experiment has to be washed in regular periods.
This ensures that surface pollution levels have been reduced and the potential for malicious reuse from GSE to flight hardware has decreased significantly.
- Isopropyl Alcohol (IPA): Analyzer grade for precision cleaning and standard cleaning and spectrum grade.
- Cleanroom tissue: Lint-free polyester.
- Vacuum Cleaner: HEPA – Filter for correctness washing.
- Acetone: Analyzer grade for precision cleaning and standard washing and spectrum grade.
- Cleanroom Swabs: Woven Polyester.
- Compressed air, filter for 0.5-micron particles.
- White light (100W).
Before using controlled areas clean, GSE must-visit for clean and apparent neatness. GSE cleaning must be clearly visible in processing sensitive layer (VC-S) MSSSL / PA / PS / Q012 to verify a visible clear level of surfaces. To achieve the cleanliness of this page, GSE should take place at three stages here:
Major cleaning – general
Courses can be conducted in clean non-clean spaces (workshops, offices, etc.). The plan is to eliminate the pollutant bulk from the tools. Nitrile gauntlets should certainly be worn while cleaning.
Standard cleaning – general
Standard cleaning should take place anteroom. Special regard should be given to exteriors, divisions, angles, vents, etc. and should be washed utilizing these suitable solvents or cleansers. All surfaces on this page require a more thorough review. Cleanroom wipes and nitrile gauntlets should be used until cleaning the middle clean.
Exactness cleaning – general
The exactness should be carried out in cleanliness, but away from hovering device (ideally at the entrance of the cleanroom). Spectro grade solvent should be applied and polyester cleanroom wipes. Mask, hood, the cleanroom formal code of rabbit costume, overshoes, and nitrile gloves should be kept in the cleanroom. A systematic and thorough facade inquiry should be out as described in MSSS / PA / PS / Q012 cleaning clearly to measure a VC-S level in order to verify a visible clear level surface processing.
- Set handling and solvent surface sensitivity. The exterior is IPA or acetone sensitive, use filter critical indifferent surfactant. Sensitive for handling the surface, limiting or eliminating the use of vacuum and handling required to check GSE scratch.
- Laptop devices are customized if the computing machine is brought to clean areas. If it is not possible, then the desktop computers must be clearly washed inside and outside in order to give special attention to the exhaust fan to the power equipment.
- Computer directors should thoroughly vacuum paying appropriate caution to monitors vents before the clear approach here.
- Computer keyboards should be flipped vertically and a jet of compressed air or nitrogen saturated with clean filters indicated in the keys before the cleanliness system listed below.
- Separate free particles from GS by thoroughly vacuum all the surfaces including gaps, divisions, and angles, including a vacuum cleaner. This process handling should not be conducted for sensitive items. Contact the nozzle directly with the GSE page and continue till a particle is visible on the GSE page.
- Easily erase with a cleanroom IPA (thorough class or equivalent). Don’t wipe or erase the solvent into the container.
- Clean the GPE surface and make IPAT flexible in the mobile phone in the one-way method. Do not ignore crevices, angles, or corners. If needed, use Sobers to separate a swim with the IPA and clean up the recovery area. Clean recessed covers with swab by revolving swab over the outside. When cleaning, replace or replace a clean surface with a fresh leaf, if the defective surfaces are corrupted. Refund swabs when apparently contaminated. Lightly remove the covering or swab with each new IPA and proceed to clean. Repeat until the GSE surface displays visible pollution.
- If the solvent is on a GSE surface, especially the blind slots or other roofs, cleaned, oil-free GN2 or air dryings. Splashing solvent and glycemic surface resistance to gas damage as GS Surface Damage. After deleting the solvent, visit the surfaces for noticeable cleaning, fixed in MSSL / PA / PS / Q012.01, to verify the surfaces at a visible level.
- A visual inquiry exposes facade contaminants, repeat, and re-inspection of solvent wiper method above. If the solvent is still visible after removing the solvent, repeat solvent wiper method with the acetone replaced for the IPA. Before applying acetone, confirm that it will not reduce the cleaned content. If the pollutant is apparent after applying acetone, contact the pollution administration manager.
- Easily erase a cleanroom dump with Sprint Grade IPA. Don’t wipe or erase the solvent into the container.
- Immerse the GPE surface with Spectro grade IPA, remove the surface in a unified method. Do not ignore crevices, angles, or corners. If needed, use Sobers to separate a swim with the IPA and clean up the recovery area. Clean recessed outsides with swab by revolving swab over the surface. When cleaning, replace or replace a clean exterior with a new leaf, if the defective surfaces are corrupted. Reconstitute swabs when clearly contaminated. Lightly remove the surface or swab with each new IPA and proceed to clean.
- If the solvent is on a GSE surface, especially the blocked spaces or other roofs, cleaned, oil-free GN2 or air dryings. Splashing solvent and glycemic surface resistance to gas damage as GS Surface Damage.
- After deleting the solvent, visit the surfaces for apparent cleaning set in MSSL / PA / PS / Q012 a. Processing to verify the surfaces at a visible level. The cleanliness level of the surface will be VC-S. A white light (100W) can be applied to help inspection. Repeat over the cleaning method until the GSE surface displays visible pollution.
- All clean GSE Wires can be sleeved in bagging Lumallalloy. The end of the lining should be bound with fresh wire tie or Captain tape.
