Title (EN) TEST FILM FOR DETECTING SURFACE PARTICLES IN CLEAN ROOM
(FR) FILM D’ESSAI POUR DÉTECTER DES PARTICULES DE SURFACE DANS UNE SALLE BLANCHE
(KO) 클린룸의 표면 입자 검출용 시험 필름
Abstract:
(EN) The present invention relates to a test film for detecting surface particles in a clean room in order to prevent inferior products by measuring the contamination level of the clean room using the surface particles. The present invention provides a test film for detecting surface particles in a clean room, the test film comprising: a substrate which has a predetermined thickness and is formed of a transparent synthetic resin material; a first adhesive layer which is formed at one side of the substrate and collects the surface particles; a release film which is adhered to the first adhesive layer and is separated from the first adhesive layer when the surface particles are collected; a second adhesive layer which is formed at the other side of the substrate; and a protective film which is adhered to the second adhesive layer so as to protect the substrate and has gradations indicated thereon. According to the present invention, there is an effect in that it is possible to easily and quickly check whether or not a clean room is contaminated by collecting, on the adhesive layer-applied surface of a substrate to which an adhesive is applied, surface particles adhered to an object to be measured, and then measuring the number, size, distribution, etc. of the surface particles with the naked eye or using instruments such as a light, a magnifier, a microscope, or the like.
(FR) La présente invention concerne un film d’essai pour détecter des particules de surface dans une salle blanche de manière à éviter des produits inférieurs en mesurant le taux de contamination de la salle blanche en utilisant les particules de surface. La présente invention concerne un film d’essai pour détecter des particules de surface dans une salle blanche, le film d’essai comprenant : un substrat qui a une épaisseur prédéterminée et est formé d'un matériau de résine synthétique transparent ; une première couche adhésive qui est formée sur un côté du substrat et collecte les particules de surface ; un film antiadhésif qui est collé à la première couche adhésive et est séparé de la première couche adhésive lorsque les particules de surface sont collectées ; une deuxième couche adhésive qui est formée sur l'autre côté du substrat ; et un film de protection qui est collé à la deuxième couche adhésive de manière à protéger le substrat et comporte des graduations indiquées sur celle-ci. Selon la présente invention, il existe un effet en ce qu'il est possible de vérifier facilement et rapidement si une salle blanche est ou non contaminée par la collecte, sur la surface pourvue d’une couche adhésive d'un substrat sur laquelle la couche adhésive est appliquée, des particules de surface collées à un objet à mesurer, et mesurer ensuite le nombre, la taille, la distribution, etc.., des particules de surface à l’œil nu ou au moyen d’instruments tels qu’une lumière, une loupe, un microscope, ou similaire.
(KO) 본 발명은 클린룸에서 표면 입자에 의한 오염 정도를 측정하여 제품의 불량을 방지하기 위한 클린룸의 표면 입자 검출용 시험 필름에 관한 것으로, 소정의 두께를 가지며 투명한 합성수지 재질로 이루어진 기판; 상기 기판의 일측에 형성되고 표면 입자가 채취되는 제1점착층; 상기 제1점착층에 부착되고, 표면 입자의 채취시 상기 제1점착층으로부터 분리되는 이형필름; 상기 기판의 타측에 형성된 제2점착층; 및 상기 제2점착층에 부착되어 상기 기판을 보호하고, 눈금이 표시되어 있는 보호필름;을 포함하는 클린룸의 표면 입자 검출용 시험 필름을 제공한다. 본 발명에 의하면, 점착제를 도포한 기판의 점착층 도포면에 피측정물에 부착된 표면 입자를 채취한 다음 육안, 라이트 또는 확대경이나 현미경 등의 기구를 이용하여 표면 입자의 갯수, 크기, 분포 등을 측정하여 클린룸의 오염 여부를 쉽고 빠르게 확인할 수 있는 효과가 있다.
