Silver paste activation detecting system

A silver paste activation detecting system for detecting an activation state of a conductive silver paste of a module to be tested, comprising:

• a power supply module configured to output a constant current;
• a test fixture electrically connected to the power supply module and configured to load the module to be tested so as to form a closed loop by connecting in series the power supply module and the conductive silver paste of the module to be tested;
• a resistor element connected in series to the closed loop;
• and
• a test module connected in parallel to the resistor element;
• wherein the test module is configured to detect a voltage value between two ends of the resistor element after the conductive silver paste is energized for at least two seconds;
• when the voltage value detected by the test module is greater than or equal to a predetermined voltage value, the test module determines that the conductive silver paste is activated;
• when the voltage value detected by the test module is less than the predetermined voltage value, the test module determines that the conductive silver paste is not activated.
