A probe card device and a disposable adjustment film thereof are provided. The disposable adjustment film is integrally formed as a single one-piece structure, and includes a probe hole and a plurality of first slots that are parallel to each other. The disposable adjustment film defines two predetermined lines respectively extending from two opposite lateral edges thereof to the probe hole. The two predetermined lines respectively extend across the first slots. In a plane that the disposable adjustment film is located thereon, when the disposable adjustment film is applied with forces that act in opposite directions and that are parallel to any one of the first slots, the disposable adjustment film is broken into two abandoned films along the two predetermined lines.

Probe card device and disposable adjustment film thereof

A probe card device includes an upper die unit, a lower die unit, a spacer sandwiched between the upper and lower die units, an impedance adjusting member, and conductive probes. The upper die unit includes a first die and a second die spaced apart from the first die. The first die has a penetrating hole, and the second die has a circuit layer. The impedance adjusting member is disposed on the second die and is electrically coupled to the circuit layer. Each of the conductive probes passes through the upper die unit, the spacer, and the lower die unit. At least one of the conductive probes includes an upper contacting segment protruding from the upper die unit and an extending arm connected to the upper contacting segment. The extending arm is abutted against the circuit layer by passing through the penetrating hole.

Probe card device and matching probe thereof

A probe carrier of a probe card device includes an upper die unit, a lower die unit, a spacer sandwiched between the upper and lower die units, and an impedance adjusting member. The upper die unit includes a first die, a second die spaced apart from the first die, and a flexible board disposed on the second die and arranged away from the first die. The flexible board includes a plurality of penetrating holes and a circuit layer. The impedance adjusting member is disposed on the flexible board and is electrically coupled to the circuit layer. The circuit layer includes at least one plated wall arranged in at least one of the penetrating holes, a part of the flexible board having the at least one plated wall is separable from the second die by receiving an internal force.
