High detection accuracy, simple operation method, no damage tothe sample to be tested; The samplesurface can be scanned for defects,Physical properties such asthickness, conductivity andpermeability of conductor samplessuch as conductor film and metalsheet were tested.
Productintroduction
.SNT -300 nondestructive testing system: It can detect the thickness, conductivity, permeability and other relatecphysical characteristics of conductor samples such as conductor film and metal plate under test without directcontact with the sample to be tested. At the same time, it can scan the surface of the sample for defects. lt can bewidely used to test the thickne ss, conductivity, permeablity and other physical characteristics of conductor samplessuch as conductor films and metal plates.

Application case/test data/photos
Surface defect measurements were made for grooves of aluminum plate samples with different depths (i.e., defects), as shown below. The defects from left to right are: (a) surface grooves with a depth of 1mm; (b) Surface grooves with a depth of 3mm; (c) is an internal groove with a thickness of 4mm from the surface; (d) is an internal groove with a thickness of 1mm from the surface; (e) is a through-hole slot; The width of each hole and slot is 10mm. Aluminum has an electrical conductivity of 3.78X10
7 (S.m
-1 ) and a permeability of 1.2566X10
-6 (H.m
-1 ).
LabVIEW program was used to control the automatic scanning system to scan the surface of the sample in accordance with the red snake path set in the figure, and set the Z-axis step distance of 1.25mm each time (you can set the specific value according to the situation), the scanning area of 70×118mm, the total number of calculated measuring points is 56×94 5264 points. In order to consider the influence of skin effect and better obtain the surface topography of the sample, the detection conditions at different frequencies of 200, 500, 1500 and 5000Hz were tested respectively. The defect location was determined by high frequency first, and then the specific size and depth of the defect was further obtained by adjusting to low frequency. Finally, the surface and near-surface morphologies of the samples were obtained.
