    Name The value
    Macrostructure and pollution Surface bands on OST 1 90082-88 should be bright, clean with no bubbles, sunsets, cracks, cavities, metallic and non-metallic inclusions and delaminations, and to meet the standards of VIAM. There may be dents, injections, removalist, prints from the rolls, if in the control the sweep depth of these defects does not display bands for the limit deviation on thickness. Allowed the presence of traces of etching strips of alloys, tint, copper plating, local darkening and stains from water. The edges and ends of the strips of solder should be smooth. Presence of cracks on the edge of edge no deeper than 2 mm. in not more than 10 PCs for one meter length of the strip.
