本発明は、ガラス、水晶、セラ□ツク等の非金属無機材
料の表面に、金属層を形成し、この金属層に半田付けを
して接合する時計部品の結合方法じ関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for joining watch parts, in which a metal layer is formed on the surface of a non-metal inorganic material such as glass, crystal, ceramic, etc., and the metal layer is joined by soldering. This is related to the same thing.
従来、時計部品の結合方法としてクロームと金を蒸着し
た非金属無機材料同志、あるいは非金属無機材料と金属
とに半田付けして結合する方法が行われてきた。Conventionally, watch parts have been joined by soldering to nonmetallic inorganic materials on which chromium and gold are vapor-deposited, or to nonmetallic inorganic materials and metals.
しかし時計部品の結合が多種にわたって応用されるに至

には適さない。However, the connection of watch parts has come to be used in a wide variety of applications, for example, the attachment of a holding wire for a crystal unit that requires extreme tensile strength requires the solder to wet the metal well when joining or soldering the parts. It is not suitable for sealing the cell part liquid crystal inlet for liquid crystal watches, or for bonding with a partner.

った。In the case of a thin film structure consisting of chromium and gold, the solder and gold form an alloy due to the heat during soldering, and the tensile strength of the holding wire is 1.0K, which makes it easy to peel off from the interface between the chrome and gold.
g/- or less, which was difficult as a method for joining watch parts.
以下、図面に基づき本発明の詳細な説明する。Hereinafter, the present invention will be explained in detail based on the drawings.

っていた。FIG. 1 is a schematic diagram of a conventional bonding method, in which a non-metallic inorganic material 1 such as glass, crystal, or ceramic is heated at 250 m
Heat to ~300°C and apply 300% chromium 2 on the surface.
~600A, then gold 7 was deposited to a thickness of 2000~3000A, and the metal wire 6 was bonded with solder 5.

その結果界面から剥離現象が生じ再現性が乏しい問題が
あった。In conventional technology, with a two-layer film of chrome, which has good adhesion to glass, and baladium, which has good adhesion and wettability to solder, the chrome and baladium are extremely susceptible to heat from the soldering iron or hot air during soldering. Baladium, which has a weak adhesion to the glass, appears on the glass substrate surface, and the adhesion at the interface between the glass substrate surface and the chrome is poor, resulting in a peeling phenomenon from the interface, resulting in poor reproducibility.
その構造にむいて引張り強度は２．０ｋｇ／ｍ４前後で
ある。The tensile strength of the structure is around 2.0 kg/m4.

約２０ＯＡ蒸着した。The glass substrate 21 is placed in a vacuum evaporation tank with a vacuum degree of 10 to 10 Torr, and at a substrate heating temperature of around 300°C, approximately 30 OA of chromium 22, which has good adhesion to non-metallic inorganic materials such as glass, is evaporated by a vacuum evaporation method. Next, approximately 200OA of nickel-23, which has excellent affinity with chromium,
Next, about 20 OA of Baladium 24, which has good adhesion and wettability with solder, was deposited.

が出来る。The purpose of the present invention is to eliminate the drawbacks of the prior art and to firmly bond non-metallic inorganic materials to metals or non-metallic inorganic materials by soldering. By sandwiching it in the intermediate layer, the shielding effect of nickel prevents the extreme diffusion of chromium and baladium against the heat during soldering, and its excellent affinity makes it possible to provide a strong metal film. .

It is obvious that silver, indium, cadmium, antimony, etc. all have good affinity with solder and can be used as crosspiece materials.
