Electrical connection defect detection device

Abstract

The invention relates to an electrical connection defect detection device for detecting whether the electrical connection between a pin to be detected of an element to be detected and a signal wire of a circuit board is normal or not. The electrical connection defect detection device comprises a signal supply, a detection module and an electrode panel, wherein the signal supply provides a test signal to the pin to be detected through a signal wire; the electrode panel is electrically connected with the detection module, and comprises a detecting surface and at least one row of through holes; the detecting surface is contacted with the surface of the element to be detected opposite to the pin to be detected; when the signal supply provides the test signal to the pin to be detected, and thepin to be detected is normally connected with the signal wire, inductive capacitance detected by the detection module is larger than a critical value; the through holes are formed along four sides ofthe electrode panel, pass through the electrode panel, and are connected with ground potential; and when the signal supply and the electrode panel are positioned at the same side of the circuit board, the capacitance effect between the signal supply and the electrode panel is shielded.

Description

technical field [0001] The invention relates to an electrical detection device, in particular to an electrical connection defect detection device. Background technique [0002] Electronic devices provide a lot of convenience in the life of modern people, making information exchange and processing more convenient and fast. Generally, there are many different chips or connectors in an electronic device, which process or transmit different data respectively, and after being arranged on a circuit board, the data is processed through the chip pins and the signal lines on the circuit board. Processing and exchange to meet the needs of users. [0003] However, the pins in the above-mentioned electronic devices and the signal lines on the circuit board often have abnormal electrical connections due to poor soldering process, thus making the electronic devices unable to operate normally. Therefore, it is often necessary to use a detection device to detect whether the electrical con...

Problems solved by technology

As a result of the close distance to the electrode plate, there will be induced capacitance between the probe and the electrode plate, which will affect the test results

[0004] This shows that the above-mentioned existing detection device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
