::: Products / Accessories / Metal, ceramic blades

By metal blades, the probe is soldered to a groove of a metal carrier. Because of this, stable mechanic guidance, constant contact force of the needle during the whole life period is provided.

This metal body can be found in various types of design. Per application the matching height and length of the body is selected. Metal carriers can be bent relatively easily, when it is necessary for the probe card fabrication.

The probe material can vary from Tungsten and Tungsten-Rhenium up to Beryllium-Cupper and Palladium.

The same way as the height of the blade body, also the tip length and tip diameter can be selected depending on the application field.

Fabrication of a ceramic blade completely differs from that of a metal blade. The needle here is soldered separately on a narrow, tinplated strip on the lower end of the ceramic body. It means, mechanic guidance here is less, which, certainly, effects stability of the whole construction.

Besides, ceramic carriers, especially, when they are only 0,010"thick, are very sensitive towards lateral loading, so they are broken relatively fast.
Ceramic blades cannot be realized in the same variety, as the metal ones. Here, on the customer's wish the matching body will be built, so far it is possible.
