Problems solved by technology

[0006] At this time, since the sticky nature of the flux affects the separation of the probe and the position fixing arm, there is a problem that the probe is damaged when a force more than necessary is applied for separation.
[0007] In addition, if the flux remains and solidifies on the elastic portion of the probe, there is a problem that the elasticity of the probe cannot be achieved and the contact of the probe cannot be performed normally

Abstract

The present invention relates to a probe for a probe card, and more specifically, to a probe for improving flux diffusion that prevents flux from diffusing along the probe when the probe is attached to an electrode of a space transformer, and its Manufacturing method. To this end, the present invention includes: a needle body portion; a needle elastic portion formed to elastically extend from the needle body portion; and a needle contact portion formed on the other side of the needle elastic portion, the needle elastic portion The body part further includes a flux preventing part formed in a groove shape for enclosing flux to prevent diffusion of flux along the needle body part.

Description

technical field [0001] The present invention relates to a probe for a probe card, and more specifically, to a probe for improving flux diffusion that prevents flux from diffusing along the probe when the probe is attached to an electrode of a space transformer, and its Production method. Background technique [0002] In general, a probe card is used to detect whether or not there is an abnormality in a wafer in a wafer process, which is a step before manufacturing a semiconductor package. [0003] Such a probe card includes a probe that is in contact with the wafer and receives a signal, a PCB that receives a signal from the probe and transmits the signal to a tester (tester), and a space transformer (spacetransformer) that transmits a signal between the probe and the PCB. ). [0004] Such probes are pasted on space transformers such as figure 1 As shown, in general, the position fixing arm 20 places the probe 10 coated with solder 5 (solder) on the electrode 30 of the sp...
