Printed circuit board component testing device

Abstract

The invention provides a printed circuit board component testing device. The device is mainly composed of a cover and a circuit board fixing base, wherein the cover can be buckled to the circuit boardfixing base through a connecting mechanism, and therefore a printed circuit board component can be safely and reliably placed in a fixing slot of the circuit board fixing base and make contact with atest probe. According to the testing device, the arrangement of a balancing rod is canceled, the structure is simple, the size is small, and in the testing process of the printed circuit board component, the test result can be stable.

Description

technical field [0001] The invention relates to the technical field of circuit board assembly testing, in particular to a printed circuit board assembly testing device suitable for active products such as implanted / interventional medical devices. Background technique [0002] As active products such as implantable / interventional medical devices continue to be miniaturized and miniaturized, more stringent design requirements are imposed on the volume of printed circuit board (PCB) components of these active products. At the same time, implantable / interventional medical devices have extremely high requirements on the safety and effectiveness of products. How to conduct comprehensive and effective testing of PCB components with complex functions and small volumes is a key point in the entire design, development and production process. Therefore, there is an urgent need for a high-efficiency and reliable PCB assembly testing device. [0003] figure 1 Shown is a schematic struc...

Problems solved by technology

[0004] 1. Complex structure, large volume and inconvenient use

[0005] 2. For cardiac pacemakers, the program control head of the program control instrument usually used to test the above PCB components cannot be close to the PCB component to be tested, so it cannot establish a short-distance communication connection with the PCB component to be tested, so the program control instrument Inconvenient testing of PCB components

[0006] 3. The signal transmission lines 1071 and 1072 are both very long. For PCB component testing of electronic products with weak signals such as pacemakers without leads, the noise in the test environment is likely to interfere with the test signal through the signal transmission lines 1071 and 1072, affecting the test accuracy. and reliability

[0007] 4. The test probes 1061 set on the top surface of the support base 104 have a relatively large pin-point spacing, which cannot meet the requirements of PCB component testing for multi-test point and micro-pitch products.

[0008] 5. The elastic force of the test probe 1062, the balance bar 105 and other structures is relatively large, and it is easy to cause damage such as bending and dark cracks to the micro PCB components during the test
