| ■Material data on probe card pins |
・Tungsten（W) W：９９．９５％
Has highest boiling point and lowest vapor pressure among metals. Also has high density and corrosion resistance. |
|
・Rhenium Tungsten (Re-W)
H３０: Re３％,K,Fe,Mo,W９９．９５％（Purity of W, Re excluded）
H３６：Re２６％,K,Fe,Mo,W９９．９５％ （Purity of W, Re excluded）
H３７：Re３％,K,Fe,Mo,W９９．９５％ （Purity of W, Re excluded）
Extension Characteristics will be increased by adding Rhenium to Tungsten. Life time will also be extended for 4 to 5 times compared with normal Tungsten. |
|
・Molybdenum（Mo） Mo：９９．９％
Has superior heat resistance and high temperature transformation characteristics. Possess high heat resistance which ordinal metal does not have. |
・Palladium（SP-1)
Au１０％、Pt１０％、Pd３５％、Ag３０％、OT３５％ |
