  • Publication number: 20140216608
    Abstract: Before the end of the treatment of metal parts in a molten salt bath nitriding/nitrocarburizing station, a chamber, arranged so that the oxygen contained in the chamber can be discharged in order to create an inert atmosphere, is filled with a refrigerant in liquid form and with a strong capacity for volume expansion as it evaporates. All the parts treated are transferred into the chamber. The chamber is closed, and the parts are left in the chamber for a preset length of time to reach a temperature at which the salt congeals and forms a protective barrier. The parts are then removed and subjected to a rinsing operation.

    Abstract: Disclosed herein is a method of manufacturing a printed circuit board, including the steps of providing a substrate including a first metal layer formed thereon, and forming a patterned first insulation layer on the first metal layer. The method further includes patterning the first metal layer to allow the first metal layer to have a pattern corresponding to that of the first insulation layer, thus forming a first circuit layer, and forming a second insulation layer on the substrate such that the second insulation layer surrounds the first circuit layer and the first insulation layer formed on the first circuit layer. The printed circuit board is advantageous in that process time and process cost can be reduced because a first insulation layer is used as an etching resist and is included as a part of a printed circuit board even after etching.
