IC Test

What is the Electrical Test?

The electrical test is an IC test made to examine the electrical parameters of each pin to pin. This includes voltage, current, silicon connectivity, and diode resistivity. This is a powerful tool to detect defective components. 


This tool detects defects such as:

  • Internal damage caused by heat and other factors

  • Overstress of electrical components.

  • ESD Damage to components


Recovered components can also benefit from the electrical component testing process to ensure they are still in good working condition.


Toyoshima Green Tech has made investments in upgrading our curve trace capabilities, a form of IC test.


Electrical Testing can be unpowered or powered.

The unpowered IC test does not add any stimulus to the electric component. In addition, the device is powered off during this test. The defects mentioned above are still able to be detected. Unpowered electrical testing is a relatively quick option. Using a working device as a control device is good for comparative functions.


Powered testing, in comparison to unpowered testing is more in depth and can detect a wider range of defects. to place an electrical component in an "active mode", we can apply up to 4 voltages to the component, testing each pin of the device accordingly.

In order to replicate certain operating conditions, we may also send signals into each device to replicate specific operating conditions. The powered electronic component test is a very powerful anti-counterfeit tool while also effectively testing for genuine but faulty ICs.
