Abstract: PURPOSE:To prevent a defective solder ball, etc., caused by water content by recovering a part of steam of a fluorine-base inert liquid generated from a liquid vessel provided with a heating heater, eliminating water content contained in steam and returning only the fluorine-base inert liquid to the liquid vessel. CONSTITUTION:The fluorine-base inert liquid 2 and water 12 of impurities stay in an impurity removing device 10. The fluorine-base inert liquid 2 is separated from the water 12 of impurities because of different specific gravity and the fluorine-base inert liquid 2 staying at the lower part because its specific gravity is heavy can be recovered in the liquid vessel 1. On the other hand, the water 12 of impurities having light specific gravity is drained to the outside via a drainpipe 15. Further, electronic parts 13 are mounted on a circuit board 14 via soldering paste and conveyed to the inside of a steam layer 4 by a conveyer 5 and subjected to reflow soldering. Accordingly, the defective solder ball, etc., caused by water content are prevented and a leak of the steam to the outside is reduced, hence the quantity of consumption of the fluorine-base inert liquid can be reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain a dielectric substrate having excellent color characteristics and good surface smoothness by forming a water-repellent layer comprising a silane- coupling agent on a substrate on which a light-shielding member is partly formed, and then irradiating the substrate surface with oxygen plasma. SOLUTION: A metal thin film is preliminarily formed on a light-transmitting substrate to form a light-shielding part between patterned pixels. A water-repellent film comprising a silane-coupling agent as the source material is formed on the light- transmitting substrate in a vacuum chamber by plasma polymn. method or vapor deposition method. Then oxygen gas is introduced into the vacuum chamber to generate oxygen plasma which is made to irradiate the surface of the light-transmitting substrate having a light-shielding part formed between patterned pixels with the plasma. Thereby, the metal thin film part as a black matrix maintains the water-repellency, while the glass part to be used for the pixel of the color filter is made hydrophilic. Then, the substrate is taken out from the vacuum chamber and an ink for dyeing is applied on the glass part.  Since the metal part maintains the water-repellency, the ink can not be spread.
