probe card circuit board

Abstract

【Item Uses】 This design provides a circuit board for a probe card used to perform electrical tests on wafers awaiting testing. 【Design Description】 Referring to the various figures, this design provides a circuit board for a probe card. The circuit board includes a substrate, four bridge bodies, and multiple pillars. The four bridge bodies are symmetrically arranged in pairs on the substrate. Each bridge body has a horizontal portion and two vertical portions. The two vertical portions are respectively connected to the two ends of the horizontal portion, forming a unique arched shape. The four bridge bodies can have a symmetrical and stable visual aesthetic. The pillars stand upright on the substrate and are arranged alternately. The pillars extend into the horizontal portions of the bridge bodies, and the tops of the pillars are exposed on the top side of the horizontal portions of the bridge bodies to form an area for electrical contact, and a dotted distribution visual aesthetic is formed on the top side of the horizontal portions of the bridge bodies. Overall, the circuit board of this probe card has an elegant and sophisticated design, presenting a more pleasing visual experience and giving people a unique and brand-new visual feeling. The dotted lines shown in the diagram represent the parts that this design does not advocate.
