Probe card device and fence-like probe thereof

A probe card device, comprising:

• a first guiding board unit and a second guiding board unit that are spaced apart from each other;
• and
• a plurality of fence-like probes passing through the first guiding board unit and the second guiding board unit, wherein each of the fence-like probes includes:
• a stroke segment being in an elongated shape defining a longitudinal direction, wherein the stroke segment has two end portions respectively corresponding in position to the first guiding board unit and the second guiding board unit, and the stroke segment has a plurality of penetrating slots arranged along a fan-out direction perpendicular to the longitudinal direction;
• a fan-out segment connected to one of the two end portions of the stroke segment, wherein the fan-out segment has a fixing point arranged away from the stroke segment;
• and
• a testing segment connected to the other one of the two end portions of the stroke segment, wherein the testing segment protrudes from the second guiding board unit and has an abutting point arranged away from the stroke segment, and wherein the fixing point is spaced apart from the abutting point in the fan-out direction by a fan-out distance,
• wherein in any two of the fence-like probes adjacent to each other, a distance between the two fixing points is larger than a distance between the two abutting points, and wherein the first guiding board unit and the second guiding board unit are not staggered with each other, and the stroke segment of each of the fence-like probes is deformable by being applied with a force to store an elastic force;
• wherein in each of the fence-like probes, a projection space defined by orthogonally projecting the testing segment toward the fan-out segment only covers at most 50% of one of the penetrating slots.
