Abstract
There are disclosed systems and methods in which a liquid dispensing head is positioned above the contact area of the device under test (DUT). A stream of liquid is dispensed from the head such that a continuous column of liquid extends from the head to the contact area of the test device. This column of liquid completes a circuit which allows current to flow thereby allowing for current measurement.
Claims20
A probe comprising:
- a liquid dispensing head adapted for being disposed apart from an electrical contact area;
- and
- said dispensing head having at least one input for receiving an electrical signal to be communicated to said contact area through said liquid when said liquid spans a gap between said dispensing head and said contact area.
A method of testing an organic light emitting diode (OLED), said method comprising:
- establishing a conductive liquid path between a test probe and a contact area of said OLED;
- and
- passing current between said test probe and said contact area using said established conductive liquid path.
A test device comprising:
- means for providing test signals;
- means for positioning a device under test (DUT);
- and
- means spaced apart from said positioning means for selectively controlling the flow of material therefrom, said selectively controlling means having at least one aperture in line with at least one contact area of a positioned DUT so as to allow said material to complete an electrical circuit for the passage of said test signals.
