4.Handheld surface copper tester/surface copper tester/surface copper detectorH18450

1. Product Overview

Handheld copper thickness tester, accurately grasping customer needs in the circuit board industry

2. Instrument principle:

The handheld surface copper tester adopts micro resistance testing technology, using four contact probes to generate electrical signals on the surface copper foil for measurement. When the probe contacts the copper foil sample, a constant current passes through the outer two probes, and the inner two probes measure the change in voltage.

According to Ohm's law, the voltage value is converted into a resistance value, and the thickness value is calculated using a certain function, which is not affected by the insulation layer and the copper layer on the back of the circuit board.

2. Product Usage:

Conduct relevant copper foil thickness testing before and after PCB and FPC cutting, drilling, electroplating, etching, and other processes.
