2015-2020 Market Analysis of Coated Dust Scrolls for Clean Room Products and Dust Collecting Equipment Consumables

1. Clean room is the removal of contaminants such as micro-particles and bacteria in the air within a certain range of space, and the indoor temperature, cleanliness, indoor pressure, air velocity and airflow distribution, noise and vibration, and static electricity. Controlled within a certain range of requirements and given to a specially designed dust-free clean room.

2, the principle of clean room. Cleanrooms use HEPA and air purification equipment. The collection rate of dust is as much as 99.97 to 99.99995%, so the air filtered by this filter can be said to be very clean. However, in addition to people, the clean room is still a dust source such as a machine. If the generated dust is diffused, it cannot maintain a clean space. Therefore, the dust generated by the air must be quickly discharged outside.

3, dust in clean room. There are three major principles in a dust-free cleanroom: dust bans, dust, and dust. As one of the buffer channels entering the clean room, the air shower is one of the best purification equipments for controlling dust, which can minimize the pollution problems caused by employees entering and leaving the clean room. The two doors of the air shower are interlocked with each other and can function as an air lock chamber to prevent outside contamination and unpurified air from entering the dust-free clean area to achieve the clean production environment required by the production workshop.

4. The main function of a clean room is to control the cleanliness degree and temperature and humidity of the atmosphere that products (such as silicon chips, etc.) touch, so that the products can be produced and manufactured in a good environment space. We call this space Clean room for clean. According to international practice, the level of dust-free purification is mainly based on the number of particles per cubic meter of air that is larger than the standard for separation. In other words, the so-called dust-free is not 100% without a little dust, but it is controlled in a very small amount of units. Of course, the dust-compliant particles in this standard are already small relative to our common dust, but for optical construction, even a little bit of dust has a very large negative impact, so in the production of optical construction products No dust is an inevitable requirement.

5. The number of fine dust particles with a particle size of less than 0.5 microns per cubic meter is controlled at 3,500 or less, and it has reached Class A of the international dust-free standard. At present, the dust-free standard applied to chip-level production and processing requires more dust than A-grade. Such high standards are mainly applied in the production of some higher-level chips. The amount of fine dust is strictly controlled within 1,000 cubic meters, which is also known as the 1K level in the industry.

Clean-up principle of dust-free paper roll clean room

Airflow → Primary Air Treatment → Air Conditioning → Intermediate Efficiency Air Treatment → Fan Pressure Supply → Purified Air Supply Pipeline → High Efficiency Air Supply Port → Clean Room → Take away Dust (Bacteria) → Return Air Clip Path → Fresh Air, Primary Air Treatment .

Repeat the above process to achieve the purpose of purification.

Clean room supplies:

In addition to clean clothes, anti-static shoes, hoods, caps, gloves, and masks used in clean room applications, there are paper stationery desks, chairs, wafer boxes, vans, notebooks, bulletin boards, dustbins, and vacuum cleaners. Etc.

Clean clothes materials are based on the condition that they will not deteriorate or emit dust after washing or other treatments, and their fabrics are not flammable, lint-free, and their weaves or fabrics do not easily pass through the contaminants and do not adhere to contaminants. In addition, friction does not generate static electricity or very high chargeability. Easy washing and regenerating, non-wrinkle, and comfortable feeling of wearing a garment are also considered for consideration. The material of the hood is made of dustless paper (or fiberless paper), and the material of the hat is the same as that of the clean clothes. When the two are worn, except for the parts of the eyes or the surface of the face only, the other parts must be covered in the head. Part of the connecting top must also be completely covered. There should be no gaps and hair should not be exposed.

Clean room shoes should fit well and comfortable to wear as the basic conditions, easy to wash, the bottom is to use plastic bottom, the cloth part can be the same as the clean clothes can be the same, the shoes should be fully dressed tightly wrapped in the heel when the shoes are worn . Glove material is thin rubber or Vinyl except for the same cloth as the clean garment. If there is any uncomfortable feeling in the process of use, or if it interferes with the touch of finger fat, the glove material will be stopped. When the glove surface is silty, it must be removed or Discontinued, in principle, the use of powder-free Vinyl gloves is better. (Cleaning first aid network partners in cooperation to provide cleaners with dust-free workshops on-site demonstrations) Clean clothes, shoes, hats, etc. must be managed by a person and cleaned regularly. The cleaning must be carried out in a clean room with pure water and cleaning solvents. And about 0.2μm filter for it, the general cleaning cycle depending on the degree of cleanliness, in the high clean area for 2 to 3 days, other areas is 5 days to 1 week, after the washing is completed and sealed immediately after drying. Washing clothes storage place must be clean rooms, spares or new product storage cabinets, while users are hanging clothes hangers for convenience.

In a clean room, people are an important factor in determining the generation of particulate contaminants. People working in clean rooms should fully understand how much personal hygiene habits affect the cleanliness of the cleanroom. This is the most important thing. Yi Qiang of the company to introduce the clean room staff should follow the procedures, related to clothing and personal supplies requirements for readers reference.

Sticky roller residue prevention:

Preventing sticking from the sticky roller The sticky roller is effective for the removal of foreign materials in the substrate manufacturing process and is an indispensable device for the substrate manufacturing process. However, its dust removal performance is also limited. For example, if it is not rolled back and forth, the dust removal effect cannot be achieved, and the residual glue generated from the sticky paper will be transferred to the weak points on the sticky roller. These residual adhesives are one of the causes of various circuit board defects. An example of a defect caused by sticky glue transferred onto a substrate by a sticky roller. In order to keep the defects to a minimum, I do not use sticky paper to directly contact the product. The cutting of the sticky paper must be done as shown.

Bandpass Filter

A filter possessing a region of transmission bounded on either side by regions of rejection is known as a band-pass filter.

Band pass filter is in a specific band to allow the light signal through, deviating from this band on both sides of the light signal is blocked. The wavelengths allowed to pass through the band can cover the ultraviolet band, visible band and infrared band.
