基板に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hollow substrate for a printed circuit, and more particularly to a hollow substrate for a printed circuit having a core material partially having a single layer of hollow.

材の絶縁が必要である部分にのみホーロ一層を形成した
部分ホーロー基板が提案されている。In recent years, hollow substrates have been used as substrates for thick film printed circuits, in which a single layer of hollow is formed on a core material made of a metal plate such as iron, and a circuit pattern is provided on the surface of this hollow layer. In this conventional hollow board, the entire surface of the core material is covered with a single layer of hollow, and as a result, a single layer of hollow exists even in areas that do not require electrical insulation, resulting in poor heat dissipation efficiency of the board, and As a board that eliminates this drawback, a partial hollow board in which a single layer of hollow material is formed only in the portions of the core material that require insulation has been proposed.

る。In the case of the above-mentioned partial hollow substrate, it is necessary to perform rust prevention treatment on the portion not covered with a single layer of hollow, that is, the non-hollow single layer. Conventionally, this anti-corrosion treatment has been carried out by applying anti-rust paint or anti-corrosion plating to the non-hollow single-layer part. It is necessary to protect the first layer of the enamel with a coating, etc., so not only is the rust prevention treatment troublesome, but if the anti-rust plating solution etc. adheres to the first layer of the enamel, the first layer of the enamel will be exposed to the plating solution. This can lead to problems such as deterioration of insulation.

たニッケルメッキ層3及びこのメッキ層3上の必要部分
に設けられたホーロ一層4によって構成されている。The present invention will be explained below with reference to illustrated embodiments. In the figure, the enamel board, which is designated as a whole by reference numeral 1, includes a core material 2 made of a metal plate such as low carbon copper, a nickel plating layer 3 applied to the core material 2, and necessary parts provided on the plating layer 3. It is composed of 4 layers of hollow hollow.
ニッケルメッキは、コア材2を硫酸ニッケル溶液に浸す
ことによって施される。このメッキの厚さが厚すぎると
きは、ホーロ一層がコア材から剥離するおそれがあるの
で、メッキ厚は1μm以下とすることが望しい。Nickel plating is performed by dipping the core material 2 in a nickel sulfate solution. If this plating is too thick, there is a risk that the hollow layer will peel off from the core material, so it is desirable that the plating thickness be 1 μm or less.

いられる。コア材に印刷されたホーローを乾燥させた後
、コア材を酸化雰囲気中で。After nickel plating, a single layer of enamel is printed on the core material. For example, borosilicate glass is used for the enamel. After drying the enamel printed on the core material, the core material is placed in an oxidizing atmosphere.

成されないからである。It is fired at a firing temperature of 650°C to 750°C. Specifically, it is fired while blowing a large amount of air, and by firing in an oxidizing atmosphere, nickel is oxidized and an oxide film is formed on the surface of the core material. The above firing temperature is relatively low (
The reason for this is that if the temperature is below 751°C, the nickel oxide layer will peel off and sufficient rust prevention treatment will not be achieved, and if it is below 650°C, complete firing of the enamel layer will not be achieved.
このようにして得られた酸化被膜は耐食性に優れている
。The oxide film thus obtained has excellent corrosion resistance.
この発明によれば、コア材にホーロ一層を印刷する前に

の高い酸化被膜が形成されており。According to this invention, a highly corrosion-resistant oxide film is formed on the non-hollow layer portion of the nickel plating layer that is applied before printing the hollow layer on the core material.
この酸化被膜によって非ホーロ一層部分の防錆がなされ
る。This oxide film protects the non-hollow layered portion from rust.
