本考案は、プリント配線板用銅張積層板の一種である金属ベース基板の耐電圧試験装置に関するものである。 This invention is based on the withstand voltage of a metal-based substrate, which is a type of copper-clad laminate for printed wiring boards.This relates to testing equipment.

従来、プリント配線板用銅張積層板は絶縁層に銅箔を積層して構成されていたが、近年金属板の片面または両面に絶縁層を介して銅箔を積層して放熱性、耐熱性などの向上を図った金属ベース基板が使用されるようになってきた。 そこで、上記の場合に金属板と銅箔間の絶縁性を測定するために耐電圧試験装置が必要となるが、従来上記装置において電圧印加端子として用いる電極は平板状のものまたは先端が半球状、針状、四角錐状の棒状などの構造を有していた。 Conventionally, copper-clad laminates for printed wiring boards were constructed by laminating copper foil on an insulating layer.However, in recent years, copper foil has been laminated on one or both sides of a metal plate via an insulating layer to improve heat dissipation and heat resistance.Metal-based substrates with improved properties have come into use. Therefore, in the above case, a withstand voltage tester was used to measure the insulation between the metal plate and the copper foil.Conventionally, the electrodes used as voltage application terminals in the above devices were flat plates.It had a rod-like structure with a hemispherical, needle-like, or quadrangular pyramidal tip.

しかしながら、上記の電極を電圧印加時に金属板に接触させる場合、平板状の電極においては金属ベース基板の銅箔、絶縁層を除くすなわち面取りにより金属板を露出する必要があるが、適切な広さ、厚さの面取りは面倒で手間がかかり好ましくない。また上記面取りをしない場合には先端針状の棒状電極を用いこれを金属板の端面に接触する方法がとられるが、金属板は通常０．５mm〜１mmと薄いために容易に接触できないという問題がある。 However, when the above electrode is brought into contact with a metal plate when voltage is applied, a flat plate-likeFor electrodes, remove the copper foil of the metal base substrate, remove the insulating layer, or cut the metal by chamfering.It is necessary to expose the board, but chamfering to the appropriate width and thickness is tedious and time-consuming.Not good. In addition, if the chamfering described above is not done, use a rod-shaped electrode with a needle-like tip.A method of contacting the end surface of a metal plate is used, but the metal plate is usually thin, 0.5 mm to 1 mm.Therefore, there is a problem that it cannot be easily contacted.
【０００４】 本考案は、端子に上記のような問題点がなく容易に金属板に電圧を印加しうる構造の金属ベース基板用耐電圧試験装置を提供することを目的とするものである。0004 The present invention does not have the above-mentioned problems with the terminal and can easily apply voltage to the metal plate.The purpose is to provide a withstand voltage testing device for structural metal-based substrates..

【０００６】 本考案に用いられるドリルとしては、金属ベース基板の厚さや取り扱い上などの点から直径０．５〜１．０mmのストレートシャンクドリルが好ましい。 さらに、金属板と接触する上記ドリルの非絶縁性である先端部の長さは先端から５０μｍ程度あればよい。また、上記ドリルに設ける絶縁性のセラミックコートの厚さは５０μｍ〜１００μｍの程度でよいことが分かった。 なお、上記セラミックコートは絶縁性を有するセラミック材からなるものであれば限定はないが、通常はアルミナ、シリカなどであり、溶射法、化学蒸着法、物理蒸着法などによりドリルの表面に形成される。[0006] The drill used in this invention has certain characteristics such as the thickness of the metal base board and handling.From this point of view, a straight shank drill with a diameter of 0.5 to 1.0 mm is preferable. Furthermore, the length of the non-insulating tip of the drill mentioned above that comes into contact with the metal plate isIt is sufficient if the distance is about 50 μm. In addition, the insulating ceramic coat installed on the drillIt was found that the thickness of the sheet may be on the order of 50 μm to 100 μm. Note that the above ceramic coat is made of a ceramic material that has insulating properties.Although there is no limitation, the materials are usually alumina, silica, etc., and can be used by thermal spraying, chemical vapor deposition,It is formed on the surface of the drill by physical vapor deposition.
