HDI PCB Board Test Equipment

Withstand current parameter tester:

The HCT withstand current parameter tester can be used to find the appropriate current parameters for the HCT withstand current test of the PCB hole chain conduction reliability test sample. The instrument adopts high-precision power module and temperature and resistance acquisition module to test samples for PCB hole chain, automatically try different currents, cycle to heat up, HDI blind hole testing machine supplier, heat preservation, cooling process, and monitor hole chain in real time temperature, current, HDI blind hole tester price, and resistance changes. Until a suitable current is found, the PCB hole chain sample meets the HCT test requirements under this current.
The HCT withstand current parameter tester can also be used for the HCT withstand current test of the PCB hole chain.

Main features of the withstand current parameter tester:

Double-sided test
When the hole chain of the test sample is designed symmetrically on both sides of the circuit board, the instrument can use the double-sided test, that is, the test current is applied to the two hole chains on both sides at the same time to test the temperature of the hole chain on the upper surface.

●Initial resistance screening
The upper and lower thresholds of the initial resistance before the test can be set, and the samples that meet the initial resistance requirements will continue to be tested.

●Test process data curve display
During the test, the HDI blind hole testing machine, the temperature of the sample, the speed of temperature change, the resistance, and the current are displayed dynamically in real time.
Data curves can be double-clicked to enlarge for observation and analysis.

Test, High Current Test withstanding current test
HCT withstand current test is a method of withstand current test. In the test, a constant DC current is applied to the hole chain, so that the hole chain rises to the set high temperature T1 within a set time (t1-t0), and then continues to apply this current, so that the hole chain is at the temperature T1 to T2. Within the range, keep the set time (t2-t1), then stop applying the current and let the pore chain cool down for a time (t3-t2) until it reaches room temperature.
During the test process, it is necessary to detect the resistance and current of the hole chain in real time.
