Vacancies Go to Cleaning Grades Measurements Services About HQ Precision Cleaning Contact Home Cleaning Grades Grade 2 Surface Cleanliness GRADE 2 SURFACE CLEANLINESS Grade 2 surface cleanliness sets very strict requirements for particle contamination on the surface of a machine part. No visible particles are allowed. Partly due to our modern water treatment installation, we easily meet the requirement of no visible particles. A 0.2mu filter, in combination with various other filters and treatments, guarantee that the rinse baths are clean from contamination and that your product comes out of our ultrasonic street clean to the correct requirement. Particles in the lithography machine disrupt the exposure pattern on the wafer and can lead to dropouts. Contamination with particles cannot be avoided during the manufacturing process, the cleaning process must be able to remove any particles that may still be present. Between cleaning during or after the making process is necessary to prevent drying of emulsions. Validation takes place on particles by means of UV and bright light inspection or if necessary. PMC. With PMC ( P article M easurement C ard) is taken a sample from a cleaned surface which is then analyzed on the number of particles. Packing in 2 layers of PE according to guidelines.

Met UV licht (golflengte 365 nm) zijn organische deeltjes vanaf 40-50 mu zichtbaar, met helder scherend licht vanaf 10-20 mu. Particle Measurement Card (PMC) meting Met een PMC test kunnen we een sample nemen van het oppervlak van een product, hierna wordt dit sample geanalyseerd op aantal en grootte van de deeltjes. Eventueel kan ook onderzoek gedaan worden naar het materiaal van de deeltjes via SEM-EDX metingen en analyse Deze worden uitgevoerd door een gekwalificeerd laboratorium.
