Description

Technical Field

[0001] This utility model relates to the field of substrate impedance detection technology, and in particular to a substrate impedance detection device. Background Technology

[0002] As electronic products become increasingly functional, their internal circuits become more complex, leading to higher requirements for the electrical performance of the substrate. To improve product quality, the impedance of the substrate is closely related to the quality of signal transmission. Detecting the substrate impedance can effectively identify potential problems, such as short circuits, open circuits, and other defects, thereby improving the overall reliability of the product. However, the design of existing substrate impedance indenters uses probes mounted on the indenter with fixed positions. This means that when the substrate impedance indenter is mounted on the fixture to detect impedance, if the probe and substrate contact points do not align or have poor contact, the frequency of alarms from the detection instrument will increase, and it will be difficult to adjust to the appropriate position later. Utility Model Content

When the substrate position is fixed and cannot be adjusted, the position of the probe can be adjusted to make good contact with the test point on the substrate, and the contact between the probe and the test point can be easily observed, thereby reducing the false alarm rate of the instrument during testing.

A connecting rod 8 is used to connect the mounting base 3 and the fixing plate 9. The end of the connecting rod 8 away from the mounting base 3 is fixedly connected to the fixing plate 9. The upper surface of the fixing plate 9 is fixedly connected to the mounting plate 10 for mounting the impedance head 11. The upper surface of the mounting plate 10 is movably connected to the impedance head 11 for mounting the probe. The impedance head 11 is provided with four second elongated holes 6 for fine adjustment of the head in the X direction. The second elongated holes 6 are provided with second fixing bolts 7 for fixing the impedance head 11. The upper surface of the mounting plate 10 is fixedly connected to a second fixing post. The second fixing post is slidably connected to the second elongated holes 6 to limit the sliding path of the impedance head 11 and reduce the number of fixing bolts, thereby reducing the workload.

[0025] The base plate 1 is provided with a first threaded hole, and the first fixing bolt 5 is threadedly connected to the first threaded hole to fix the mounting base 3. The first elongated hole 4 and the second elongated hole 6 are double-layer holes, and the radius of the upper hole is larger than that of the lower hole to fix the bolt sliding. The impedance head 11 is made of transparent acrylic to facilitate the observation of the contact between the probe tip and the substrate. A probe is installed on the impedance head 11 for detection.

After adjustment, the bolts are fixed again, and the test is performed.
