Another probe head includes the aforesaid probe seat, an electrically conductive layer partially inside the probe seat and partially outside the probe seat, a first spring probe penetrating through the probe seat, and a shorter second spring probe penetrating through the lower die in a way that a top end of the second spring probe is located inside the probe seat and abutted against the electrically conductive layer. As such, fine pitch requirement and different high frequency testing requirements are fulfilled.

Abstract: A probe head includes a probe seat, a first spring probe penetrating through upper, middle and lower dies of the probe seat for transmitting a first test signal, and at least two shorter second spring probes penetrating through the lower die for transmitting a second test signal with higher frequency. Two second spring probes are electrically connected in a way that top ends thereof are abutted against two electrically conductive contacts on a bottom surface of the middle die electrically connected by a connecting circuit therein. The lower die has a communicating space and at least two lower installation holes communicating therewith and each accommodating a second spring probe partially located in the communicating space. The probe head is adapted for concurrent high and medium or low frequency signal tests, meets fine pitch and high frequency testing requirements and prevents probe cards from too complicated circuit design.

Abstract: A vertical probe device includes a lower die having engaging holes and needle holes, a positioning film having limiting holes and needle holes, probe needles inserted through the needle holes, and supporters having at least an upper stopping surface and at least a lower stopping surface for moveably limiting the positioning film therebetween. Each supporter has a head, a neck passing through the limiting hole and having a length longer than the thickness of the positioning film, a body, and a tail inserted into the engaging hole, which are connected in order, and at least one of the upper and lower stopping surfaces. The supporters can prevent the positioning film from being lifted and flipped over and enables the positioning film to move so that the probe needles are reliable.

Abstract: A positioner and a probe head of a probe card are provided. The positioner has a main opening, a first sub-opening, a second sub-opening, a third sub-opening, a fourth sub-opening, a first positioning portion, a second positioning portion, a first elastic portion and a second elastic portion. The first sub-opening, the second sub-opening, the third sub-opening, and the fourth sub-opening are sequentially arranged at the periphery of the main opening and are communicated to the main opening. A stiffness of the first positioning portion and a stiffness of the second positioning portion are higher than a stiffness of the first elastic portion and a stiffness of the second elastic portion.

Abstract: A light emitting device comprising a light guiding frame and a light source is provided. The light guiding frame has a recess, and an edge of an opening of the recess defines a light-emitting opening. The light guiding frame comprises a first light guiding structure and a second light guiding structure connected to the first light guiding structure. The light source is disposed on a bottom of the recess and has a light-emitting surface. The first light guiding structure is extended along a direction away from the light-emitting surface and the light-emitting opening. The second light guiding structure is extended along a direction away from the light-emitting surface but close to the opening.

Abstract: A lighting device is provided. The lighting device includes an optical reflection plate, a light holder, and at least one light source. The optical reflection plate includes a non-reflective region located in the center of the optical reflection plate, and a plurality of reflection regions surrounding the non-reflective region in sequence. The light holder is located on the non-reflective region of the optical reflection plate and includes a circle side-light concave portion. A light-emitting opening of the side-light concave portion faces to the reflection regions. The light source is located in the side-light concave portion of the light holder. When the light source emits light, the light emitted from the light source is reflected by the reflection regions.
