Abstract: A probe structure includes a tube body and a pin body. The tube body has a central axis and includes a first rigid section, a first spring section, a second rigid section, and a second spring section. The first spring section surrounds the central axis and extends in a direction along the central axis. Two ends of the first spring section connect to one end of the first rigid section and one end of the second rigid section. The first spring section and the second spring section are different in spring constant. The pin body passes through and is disposed in the tube body. The pin body has a head section protruding out of the first rigid section, and the head section is fastened to the first rigid section.

Abstract: A spring probe includes a spring sleeve and a needle having a body located inside the spring sleeve and a head protruded out of a lower non-spring section of the spring sleeve and having a stopping block. The lower non-spring section is abutted against and fixed to the stopping block, facilitating assembly of the spring probe. A method for manufacturing the spring probe is disclosed including the steps of forming a spring sleeve having a lower non-spring section with a slot and a guiding sheet adjacent to the slot by photolithography technique, manufacturing a needle having a stopping block with a bonding pad and an engagement rib by MEMS manufacturing process, sleeving the spring sleeve onto the needle to engage the engagement rib into the slot, and fixing the guiding sheet and the needle together by reflow soldering the bonding pad.

Abstract: A trace embedded probe device includes a circuit board including an insulating layer unit whose upper surface has first recesses and a second recess located therebetween, grounding traces and a signal trace whose trace main bodies are disposed in the recesses respectively and flush in elevation with the upper surface, and a grounding layer disposed on a lower surface of the insulating layer unit and connected with the grounding traces by conductive vias penetrating through the first recesses and the lower surface and provided therein with conductive layers. The trace main bodies, grounding layer and conductive layers are made of a same metal material. Probes are disposed on the grounding and signal traces respectively. The probe device is easy in control of distance, width, thickness and surface roughness of the traces, and beneficial to achieve the requirements of thin copper traces, fine pitch and high frequency testing.

Abstract: A probe card includes a probe seat having upper and lower dies and a probe accommodating hole, a spring probe inserted through the probe accommodating hole and including a spring sleeve having upper and lower non-spring sections, and a circuit board disposed on the upper die and having a contact pad against which the spring probe is abutted. At least one of the upper and lower dies has a stopping surface partially facing the probe accommodating hole and an extended portion inserting hole in alignment with the probe accommodating hole. At least one of the upper and lower non-spring sections has a cylinder portion abutted on the stopping surface and an extended portion inserted through the extended portion inserting hole.

Abstract: A spring probe includes a needle, a spring sleeve sleeved onto the needle, and a protrusion. The spring sleeve has upper and lower non-spring sections, and at least a spring section therebetween. The needle has a bottom end portion protruding out from the lower non-spring section, and a top end portion located in the upper non-spring section. The protrusion is located at one of the top end portion and the upper non-spring section. The needle is movable relative to the upper non-spring section from an initial position to a connected position where the upper non-spring section is electrically connected with the needle through the protrusion when receiving an external force. As a result, the spring probe effectively prevents signals from being transmitted through the spring section, thereby improving stability of signal transmission and preventing the spring section from fracture.

Abstract translation: 弹簧探针包括针，套在针上的弹簧套和突起。 弹簧套筒具有上下非弹簧部分，并且至少在其间具有弹簧部分。 针具有从下部非弹簧部分突出的底端部分和位于上部非弹簧部分中的顶端部分。 突起位于顶端部分和上部非弹性部分中的一个处。 针可以相对于上部非弹簧部分从初始位置移动到连接位置，在接收外部力时上部非弹簧部分通过突起与针体电连接。 结果，弹簧探针有效地防止信号通过弹簧部分传递，从而提高信号传输的稳定性并防止弹簧部分断裂。
