Product Description

Automatic Four-Wire Millimeter-Resistance Testing Machine
Our company unique four-wire test can measures mΩ resistance value, with higher accuracy, faster speed, low labor cost, low maintenance cost, can complete two-wire and four-wire testing at the same time.

Product Features

1) Effectively detect the hole void of point type and hole void of line loop;
2) It is for four wire mid-test of semi-finished and four wire finished product test;
3) Two wire and four wire can complete the test at one time;
4) Four wire/two wire test can set up test points freely;
5) High speed/high accuracy four wire test;
6) Without cables, only 3 mins can install pinblock type fixture;
7) The latest testing technology, speed increase 30%;
8) The large panel test size can test hole break for semi-finished product.


Four-wire electrical test principle
 
  1. The four-wire electrical test is specifically used to test the resistance of very small internal vias. It is also called the four-terminal resistance measurement method. It can accurately measure low resistance without contact with lead points or resistive properties.
  2. The four-wire electrical test is divided into two parts. The first part of the test produces a fixed current, the second part of the test measures the voltage. Since no current flows in the second part of the test, the resistance of the contact will be canceled out.
  3. The "true resistance value" is accurately calculated through the through-hole measurement.
  4. In the traditional single-probe test, only one wire and one probe are connected. For the four-wire electrical test, the double probe needle will have two wires connected to the two probe tips respectively.
