technical field

The utility model relates to the field of circuit board detection equipment, in particular to a fixture for a high-efficiency, energy-saving and precise detection device for circuit boards.

Background technique

The bed of needles method is usually used in the detection of circuit boards. In this method, a spring-loaded probe is connected to each detection point on the circuit board. The spring makes each probe have a pressure of 100-200g to ensure that each detection point is in good contact. Such probes arranged together are called "needle beds". Under the control of the detection software, the detection points and detection signals can be programmed, and the inspector can obtain the information of all test points. Actually only those probes are installed for the test points that need to be tested. Although it is possible to inspect both sides of the board at the same time using the bed of needles test method, when designing the board, all inspection points should be on the solder side of the board. Bed of needles tester equipment is expensive and difficult to repair. The needles are selected according to the specific application of different arrangements of probes, but when using this method, the circuit board sometimes moves during the detection process, which reduces the detection effect, and sometimes deviations occur, resulting in poor detection results , so it is necessary to design a circuit board high-efficiency energy-saving precision detection device fixture.
