Problems solved by technology
In order to meet good electrical performance and detect the reliability of the printed circuit board in advance, it is necessary to install loads on multiple ports on the printed board. For the traditional test method, the load is usually installed by soldering RF connectors at all the tested port positions. Although the test method is intuitive, it has complex operations. After the test is completed, the load needs to be removed by desoldering. At the same time, it is easy to cause damage to the metallized vias of the printed board.

The invention discloses a non-welding type rapid test mechanism for a printed board. The invention relates to the technical field of active phased array radar antenna array planes. The mechanism comprises elastic pinhead radio frequency connectors, a structure fixing plate, a tested printed board and a fastener. The mechanism is reliably in contact with corresponding tested ports of the tested printed board in a non-welding manner through a plurality of elastic needle connectors; an internal circuit of the tested printed board is communicated, and a non-welding test is carried out on the printed board only by adopting the structure fixing plate and the elastic needle radio frequency connectors, so that the defects of large workload, complex operation and easy damage to the printed board caused by welding connector-test-desoldering connector in the traditional test process are overcome; through the refined size chain design of the appearance of the radio frequency connector probe and the appearance size of the fixed plate, the reliable contact between the connector probe head and the edge of the printed board metallized hole is ensured, the inner wall of the printed board metallizedhole is not damaged, and the reliability and operability of the printed board test are improved.
Description
technical field [0001] The invention relates to the technical field of active phased array antennas, in particular to a non-welded fast testing mechanism for printed boards. Background technique [0002] The printed board is an important carrier of electrical performance such as the antenna unit, internal detection network, and integrated layer in the radar, and is an important part of realizing radar performance and tactical indicators. With the rapid development of active phased array radar technology, requirements such as easy installation and disassembly, and reliable testing are also put forward for the testing of large quantities of antenna units. In order to meet good electrical performance and detect the reliability of the printed circuit board in advance, it is necessary to install loads on multiple ports on the printed board. For the traditional test method, the load is usually installed by soldering RF connectors at all the tested port positions. Although the tes...
