100% Visual Screening as per MIL-STD-883 Method 2032 |
When inspected under 7X - 30X magnification, capacitors will be uniform in quality and free from pits, cracks, adhered foreign material and other defects which will affect life or serviceability. There will be no demetallization (lift-off, blisters or roll back), voids or scratches on the electrodes which expose the dielectric over more than 5% of the area. |
