Abstract: A cantilever contact probe comprises at least a probe body and a hook-shaped end portion, being joined to the probe body and ending with a slanted section being configured as a hook. The end portion is bent at a bending point having a suitable inclination of the hooked slanted section with respect to a longitudinal extension axis of the probe and ends with a contact tip being able to assure a mechanical and electrical contact with a contact pad of a device under test. Suitably, the probe comprises at least a reduced portion having a first area with at least a first size being smaller than a corresponding first size of a second area of the probe in a section which does not comprise the reduced portion, along a side by side placing direction of the probes within a testing head. The reduced portion is substantially reduced along its sides thus forming an area having a reduced cross size being placed edgeways.

Abstract translation: 悬臂接触探针至少包括探针体和钩形端部，其连接到探针主体并且以配置为钩的倾斜部分结束。 端部在弯曲点处弯曲，该弯曲点具有相对于探针的纵向延伸轴线的钩形倾斜部分的适当倾斜度，并且端部具有能够确保与装置的接触垫机械和电接触的接触尖端 被测试。 适当地，探针至少包括具有第一区域的缩小部分，第一区域具有至少第一尺寸小于在不包括减少部分的部分中沿着并排的第一尺寸的探针的第二区域 将探头的方向放置在测试头内。 减小的部分沿其侧面大大减小，从而形成具有减小的交叉大小的区域被设置为边缘。
