CLEANROOM BASICS : 

CLEANROOM BASICS What is a Clean room? A clean environment designed to reduce the contamination of processes and materials. This is accomplished by removing or reducing contamination sources.

Cleanroom BASICS : 

Cleanroom BASICS A cleanroom is a controlled environment that regulates the following: particulate matters in the air( i.e. dust and other particles) temperature humidity pressure contaminants from people, machines, etc.

Cleanroom BASICS : 

DEFINITION OF TERMS An enclosed space employing control over the particulate matter in the air, temperature, humidity, pressure and human contributed contaminants. A defined space in which the concentration of airborne particulate matter, including human contaminants is controlled to specified limits. CLEANZONE CLEANROOM Cleanroom BASICS

CEILING GRID : 

CEILING GRID GLASS WINDOWS WALL PANELS CONDUCTIVE FLOORS OR RAISED FLOOR Basic components of Cleanroom

Slide 9: 

AIR SHOWERS FULL GLASS WINDOWS PASS BOX ANTE ROOM Basic components of Cleanroom

Cleanroom at construction stage : 

BUILDING/CONSTRUCTION CIVIL WORKS ELECTROMECH WORKS Cleanroom at construction stage

Cleanroom stages of construction : 

CIVIL WORKS INTERIOR WORKS Columns Slabs Walls Sanding and Painting Secondary Ceiling and Installation Painting Works ELECTRO-MECH’L WORKS INTERIOR WORKS Piping Works Equipment Installation Support System Installation Lightings Fire Protection ENCLOSURE Enclosure of area and issuance of access route To remove the generated dust before it spread OTHERS Main Feeder line Other Electromechanical Works and etc. Cleanroom stages of construction

Basic Cleanliness Requirement : 

Basic Cleanliness Requirement Materials To be stored in a clean & orderly manner Others Dirty Work to be isolated Sweep daily Wet with sawdust

5S and Housekeeping : 

5S and Housekeeping Every user is responsible for keeping the cleanroom clean Always clean your workspace before leaving Don’t leave or store items on or in equipment Do not set liquids on any equipment Properly store all materials before leaving the cleanroom Last one out should make sure the room is in a safe idle mode

Cleanroom apparels & PPE : 

static dissipative smocks 3. Facemask 1. head cap / headgear In-plant shoes/ safety shoes 2. Safety Glasses Cleanroom apparels & PPE

Slide 18: 

Cleanroom: REQUIRED COMPLETE APPAREL 2. facemask 3. bunny suit 4. booties over in-plant shoes 1. hair net (before hood) Ultra Clean suit & apparels

BASIC CLEANROOM PROTOCOL : 

Entrance Control Air lock room Sticky/Tacky mats Materials & Tools clean materials to be brought into the building clean materials before entering BASIC CLEANROOM PROTOCOL

Cleanroom PRACTICES : 

Cleanroom PRACTICES All workers must attend an orientation, Chemicals must be approved Equipment and materials must be cleaned Moving must be done with care Eating, smoking and the chewing gums is prohibited Housekeeping

Cleanroom requirement : 

Cleanroom requirement No visible dust No rust, no peeling paint No sand/pebbles No fiber/hair, wood chips No plastic debris, carbon/paper No styro foam chips No presence of food

Slide 22: 

Implementing Clean Production Environment Cleanroom requirement & practices

APPLICATION OF 4 PRINCIPLES : 

APPLICATION OF 4 PRINCIPLES

Slide 24: 

・ install air shower/pass box - prevent dust from entering during opening/closing of doors -dusting off before entry ・　pressurize the room(cleanroom indoor) to prevent entry of dust from outside air shower pass box ・ provide sticky mat 　place mat near entry points to prevent dust under the shoes from entering Prevent entry of dust basic control measures(1) ＪＡＣＡ >１０Ｐａ (１.０２mmAq） ＦＤＡ >０.０５inAq （１.２７mmAq） ISO13408-1 １０～15Ｐａ

Slide 25: 

Prevent entry of dust basic control measures(2) wear cleanroom suits/gown ban use of cosmetics use of low/non-particle generating finishing materials

Slide 26: 

people manufacturing equipment tools processes/utilities(CDA, N2, DI water) office equipment and supplies(computers, papers) molds, fungi, bacteria structural materials(paint peels, outgassing) Cleanroom CONTAMINANT

What is STATIC ELECTRICITY? : 

What is STATIC ELECTRICITY? - It is an electrical charge at REST. ELECTROSTATIC DISCHARGE (esd)

We generate static electricity when…. : 

We generate static electricity when…. When a footwear of a person separates from the floor, it creates friction which is a source of electrical charge. Electrical charge is created by changes in capacitance as follows; When a person moves, clothing separates from body parts. This creates friction which is a source of electrical charge. When a person moves, the body parts rub with the surrounding air. Friction caused by contact and separation generates electrical charge.

Slide 31: 

1. Prevent entry of dust. Minimize sources that generate dust. Remove the dust generated in the room before they spread. 4. Do not accumulate and scatter the dust. 4 Principles of Maintaining Cleanliness
