In practice
Where the DR370A is used
Check conformal-coating thickness on populated boards, keep the probe on small test pads and read the result on the colour screen. Built for PCB coating checks rather than general metal thickness.
01
Conformal coating on PCB
Eddy current
Measure conformal-coating thickness on conductive PCB surfaces with an eddy-current probe, without damaging the coating.
Suitable conductive substrates only; confirm the coating type before measuring.
02
Thin boards, small pads
0.05 mm substrate
A 0.05 mm minimum substrate thickness and a Φ12 mm minimum measurement area suit thin boards and small test pads.
At curved areas the radius must be at least 5 mm convex or 25 mm concave.
03
Colour readout, built-in cell
2.8-inch colour screen
1250
μm · measuring range
Reading, group number and max / avg / min are shown together on the colour screen; the 3.7 V 3000 mAh cell is rechargeable.
Stated accuracy is ±(2% of H + 1.5 μm); confirm suitability for your coating and board.
