This disclosure provides a probe card for electrical testing a chip in a wide temperature range. The probe card includes a circuit board, a cover, a circular supporter positioned on the circuit board, at least a probe needle fixed on the circular supporter by an adhesive, and a flow line positioned in the space between the circuit board and the cover. Embodiments of the invention moderates the temperature of the probe card by introducing a fluid such as, for example, forced-air or nitrogen into the flow line to carry heat into or out of the probe card.
