Clean room structure<\/h2>\n

\"\"<\/a>There is a 220m2 clean room on the 2nd floor of the second Yagi Factory.
\nA clean production environment eliminates bacteria by removing dust from products, making it possible to produce products with extremely few pollutants.\n\n<\/p>\n

A conventional clean room is a large-scale facility because clean air is supplied from an external fan through a duct behind the ceiling.
\nThe FUTA – Q clean room is the latest energy-saving and improved type that eliminates the need for external machine rooms and duct work behind the ceiling.
\nThe structure is that a HEPA filter unit is attached to the top of the Daikin air conditioner.
\nIt is a method that slowly blows laminar clean air from four balloon ducts installed on the ceiling, and the cleanliness specification is class 10,000.
\nA positive pressure FFU (FUN + HEPA filter) is also installed to prevent the inflow of outside air.\n<\/p>\n<\/div>\n\n\n\n

Clean room management<\/h2>\n\n

\"\"<\/a>\u2460 Change into dust-free clothing, hood, and electrostatic shoes exclusively designed for the clean room before entering the room.
\n\u2461 The room goes in and out through the air shower with double seat shutters.
\n\u2462 Clean the floor in every corner with a special cleaning mop at the start of work.
\n\u2463 Wear clean gloves and a mask for assembly and inspection work.
\n\u2464 We will establish and follow the rules of prohibited items such as the use of paper such as corrugated cardboard and pencils that generate dust.
\n\u2465 Positive pressure inspection of the clean room with a differential pressure gauge and periodic inspection and management of cleanliness with a particle counter are performed.\n<\/p>\n\n<\/div>\n\n\n\n

Cleanliness measurement and evaluation of clean room<\/h2>\n

\"\"<\/a>Based on the JIS standard, the cleanliness of 22 points was measured and evaluated for 0.5 \u03bcm particles with a particle counter.
\nThe evaluation result of cleanliness in the area achieved class 1000 (ISO class 6).
\nThe average value is 127 \/ CF (20-260 \/ 10 minutes), which is considerably better than class 1000, and the clean room performance evaluation is highly acceptable\nThe photo on the right shows the measurement result. .The number of Particles of 0.5 micrometer’s diameter was counted for 1minute inside the clean room.
\nSince the number of particles was 22 on the screen, There were 220 particles \/ cf * when converted to 10 times.
\nWhen measured from the clean room one step outside (point b), it was 1.51 million pieces \/ cf.
\nThere was a difference of about 7,000 times, and which demonstrates the high cleaning performance of the clean room.\n\n<\/p>\n<\/div>\n\n\n\n

\n

Processing Parts that requires clean management by utilizing a clean room,
\nassembly and packing work is arailable.
\nWe are also able to mass-produce products, so we look forward to hearing from you.\n<\/p>\n
