Problems solved by technology

While this keeps the design as simple as possible, it takes up a lot of space and doesn't shield well
On the other hand, the existing shielding structure cannot realize mutual shielding between multiple boards under test and mutual shielding between modules on the board

Embodiment

[0023] Embodiment: A kind of PCBA radio-frequency isolating device, take the direction of use as a reference, the PCBA board 3 to be tested is detachably placed on the carrier board 4, including upper and lower shields 2, 6, and the lower shield is located on the carrier board The lower end of the upper shielding cover is located above the PCBA board to be tested, and several chambers 21 are arranged in the upper and lower shielding covers, and a detachable set is provided between the lower shielding cover and the carrier board. Several module shielding boxes 5 .

[0024] The side of the lower shield facing the PCBA board to be tested is provided with a ring of cavity contours 22 distributed in a tooth-like structure. The profile of the cavity distributed in a tooth-like structure is customized according to the appearance of the PCBA.

[0025] It also includes upper and lower needle boards 7, 8, the lower needle board is fixed below the lower shield, and the upper needle boar...

Abstract

The present invention discloses a PCBA RF isolation apparatus, characterized in that a PCBA board to be tested is detachably arranged on a support plate on the basis of use direction. The PCBA RF isolation apparatus comprises an upper shielding can and a lower shielding can, wherein the lower shielding can is arranged at the lower end of the support plate, the upper shielding can is arranged over the PCBA board to be tested, both the upper shielding can and the lower shielding can are provided with a plurality of cavities therein, a plurality of module shielding cases are detachably provided between the lower shielding can and the support plate, the plurality of module shielding cases are respectively arranged at upper and lower sides of the PCBA board to be tested through the upper shielding can and the lower shielding can, so that a shielding structure hardly occupies the extra volume; as both the upper shielding can and the lower shielding can are provided with the plurality of cavities therein, mutual shielding among a plurality of boards which are in test at the same time can be achieved, a module to be tested can be picked and placed conveniently, at the same time, a shielding effect also can be ensured; through the module shielding cases, shielding for a certain module is achieved, in this way, the shielding effect can be ensured, the whole structural design is simple and operation is convenient, and no extremely large volume is occupied.

Description

technical field [0001] The invention relates to a PCBA fixture, in particular to a PCBA radio frequency isolation device. Background technique [0002] Electronic products generally require ICT testing (In Circuit Test) or FCT testing (Function Circuit Test) after production is completed. In the FCT test, the radio frequency module will work. To ensure that the test results are not interfered, this part needs to be shielded. This requires the design of a dedicated shielding structure. How to ensure the convenient operation of the jig under the condition of effectively shielding the board without occupying too much volume, there is still a lack of an effective technical solution. [0003] The traditional PCBA test fixture needs to include a pressing device, a carrier device and a needle board. There are slots on the carrier board for specially placing the test board, and the pressing down makes each test pin completely contact the test position on the PCBA circuit board. T...
