What is the difference between copper plates (transverse thickness difference) and how to detect them?
The method of measurement is defined by measuring the thickness at different points on the cross section, and subtracting the nominal thickness (that is, the thickness of the mark), which is the difference in the transverse thickness. General requirements are measured with vernier calipers.
The transverse thickness difference, mean deviation between different plates in cross section measurement of the thickness of the point, this is decided by the production equipment, inevitably there will be, but he has an allowable range, the plate thickness deviation range of good quality small.
