Abstract: A chip test device is provided for using a printed circuit board to perform a test process. The printed circuit board includes a pin probe socket having a plurality of pin probe holes. A chip to be tested includes a plurality of protruding electrodes. The chip test device comprises a test base for electrically coupled to the chip to be tested, a plurality of elastic first pin probes, and a test converting board having a first layer with a plurality of pin probe holes coupled to a corresponding one of the protruding electrodes and a second layer with a plurality of second pin probes coupled to a corresponding one of pin probes on the printed circuit board.

Abstract: An apparatus for the removal of particles existing in exhaust gases by directly sprinkling the gases with water to congeal the particles. The apparatus also mixes surfactants into the water, and the mixture is driven by a pump to clean out the condensation deposited in a transmitting conduit in order to eliminate settled congealed particles that could block the transmitting conduit.
