2000 - As tested and recorded, Amber ABS material used in Pozzetta PL500, PL535, PL600, and PL655 photomask boxes. Six sample boxes, chosen at random from production run, were tested. The sample boxes were isolated using ceramic as the surface on which samples were laid. The surface resistivity reading was taken with the resistivity/resistence meter in direct contact with the sample. Static surface charge reading was taken with the static field meter at the pro-per, uniform distance above each sample as prescribed by the meter's indicator light. Each sample was charged, after initial readings, by the identical pattern of passing a vinyl glove repeatedly over the sample, with the glove dragging across the sample. The static surface charge reading was recorded at intervals, after charging, immediately, 10 minutes,20 minutes, and 90 minutes. |
