Description
図1は、本発明のプローブ針の一例の概略を示す断面図であり、図2は、本発明のプローブ針の一例を示す部分断面図である。
次に、本発明のプローブ針の製造方法について説明する。
金属基体である直径0.085mmのタングステンを、30%水酸化カリウム溶液を用いて、40℃で3分脱脂し、次いで20%塩酸を用いて、30℃で1分酸洗いを行った後、塩化ニッケル250g/L及び塩酸100g/Lからなる無光沢ニッケルめっき層形成用の塩化ニッケルめっき液に浸漬し、温度25℃、陰極電流密度5A/dm2で、3分間通電することにより、厚さ0.02μmの無光沢ニッケルめっき層を形成した。
実施例1において、金合金めっき層としてAu−Co合金めっき層を以下に示すように形成した以外は、実施例1と同様の方法で実施例2のプローブ針を作製した。
実施例1において、光沢ニッケルめっき層を形成する際に光沢剤としてチオ尿素100ppmを用いた以外は、実施例1と同様の方法で実施例3のプローブ針を作製した。
実施例1において、金属基体としてBeCW(ベリリウム銅線)を用い、光沢ニッケルめっき層を形成する際に光沢剤としてチオ尿素100ppmを用いた以外は、実施例1と同様の方法で実施例4のプローブ針を作製した。
実施例1において、金属基体として直径0.080mmのBeCW(ベリリウム銅線)を用い、光沢ニッケルめっき層を形成する際に光沢剤としてチオ尿素100ppmを用い通電時間を20分として光沢ニッケルめっき層の厚さを4μmとした以外は、実施例1と同様の方法で実施例4のプローブ針を作製した。
実施例1〜5のプローブ針について以下の接触繰り返し試験を行った。この接触繰り返し試験は、プローブ針の長さ方向の両端から応力を与え、そのプローブ針の弾性力を利用して被測定体の電極(ここでは、コンタクト板を使用した。)に繰り返しコンタクトさせる試験であり、その評価方法としては、所定の回数繰り返しコンタクトさせた後のプローブ針の磨耗や剥離等について観察した結果で判断した。

9 基端部
Claims (1)
- 先端部を被測定体の電極に接触させて該被測定体の電気的特性を測定するためのプローブ針であって、
金属基体と該金属基体の表面を覆う金属層とを有し、該金属層が、前記金属基体側から無光沢ニッケルめっき層、光沢ニッケルめっき層及び金合金めっき層の順で積層された構造であり、
前記金合金めっき層が金と鉄族元素とを含む金合金からなり、当該金合金中の金含有量が93.0〜99.5重量%であり、該金合金めっき層の硬さが、Hv180〜350の範囲内であり、
前記金属基体の表面粗さをRa1(μm)、前記光沢ニッケルめっき層の表面粗さをRa2(μm)、前記光沢ニッケルめっき層の厚さをX(μm)とし、Ra2/Ra1=Yとしたとき、下記式1及び2の両方を満たすことを特徴とするプローブ針。
