Abstract
The utility model relates to a radio frequency PCB testing device based on rf probe and rotary joint base to radio frequency printing board. To install the base of rf probe through rotary joint and spring and be in the same place with the base assembly of installation printing board, and make the base of installing the rf probe possess the rotatable function of lifting up and can compressing tightly automatically simultaneously. Wherein the rf probe uses and has elastic probe for the probe can well contact with the RF port of printing board. Adopt 4 stands to provide the positioning action for the installation of printing board on the printing board base. Only need lift up the base of the installation rf probe at both ends during the test, place the printing board that awaits measuring and to test in the middle of the base of installation printing board. This device can screen the test before the board load module is printed to the radio frequency, overcome printing board load module chronic, dismantle trouble shortcoming, can effectively improve the efficiency of software testing of radio frequency printing board.
Description
Technical field
The present invention relates to a kind of radio frequency PCB testing device, more particularly, to one kind can be before radio frequency printed board load modules
Its radio-frequency performance is quickly tested and the radio frequency printed board based on rf probe and rotary joint pedestal of batch testing is surveyed
Trial assembly is put.
Background technology
With the development of electronic technology, the batch production of printed board and inspection become an important research topic.Currently
Printed board processing correctness generally detects by x optical detector in PCB Production producer；Surface Mount producer is generally examined by x light
Survey instrument to detect the Surface Mount effect of device in printed board, if there is short circuit or rosin joint.However, because a lot of surface mounting components adopt
Qfn or bga etc. encapsulates, the possibility of the detection of x light nor exclusion printed board rosin joint and short circuit completely.
DC test is another kind of method for checking printed board and surface mounting component effect, and the method is printed for low frequency
It is effective for plate.But for radio frequency printed board, DC test cannot be checked its radio-frequency performance thus cannot function as
Radio frequency printed board whether can normal work basis for estimation.
Man of complete system plant is generally tested after printed board load module complete for Surface Mount, and this can check radio frequency printed board
Radio-frequency performance.However, the installation time that this method needs is longer, go wrong if it turn out part printed board performance, need
Again to dismantle printed board to complete to keep in repair.This prints panel products for the very big radio frequency of batch and can waste a lot of manpowers and thing
Power.Therefore, quick test and the batch testing of radio-frequency performance is met in the urgent need to a kind of new radio frequency PCB testing device
Demand.
Content of the invention
It is an object of the invention to provide the survey of a kind of quick test and its radio-frequency performance of batch testing for radio frequency printed board
Trial assembly is put, and can carry out filler test before radio frequency printed board load module, will be direct for printed board that device has Surface Mount problem
Return the maintenance of paster manufacturer, save the process of middle installation and removal.This device to test speed is fast, can complete one piece in 20 seconds
The radio-frequency performance test of Common radio frequency printed board, is suitable for large-scale production and adopts.
The technical solution that the present invention is adopted by its technical problem of solution is: will be installed by rotary joint and spring
The pedestal of rf probe is assembled together with the pedestal installing printed board, so that the pedestal of installation rf probe is provided simultaneously with rotatable
Lift and can automatic impaction function.Wherein rf probe is using having resilient probe so that the radio frequency of probe and printed board
Port can be with good contact.Spring can control the pedestal rotation installing rf probe to lift or automatic impaction.Printed board is installed
Pedestal on to devise 4 root posts be to print plate positioning device, good positioning precision can be reached and adjust without manual
The position of printed board.The pedestal of the installation rf probe at two ends only need to be lifted during test, put in the middle of the pedestal installing printed board
Put printed board to be measured can be tested, the Installation And Test process of printed board is very convenient.
Compared with prior art, its remarkable advantage is the present invention: before radio frequency printed board load module, radio frequency can be printed
The radio-frequency performance of plate is tested, and overcomes printed board load module time length, dismantles troublesome shortcoming, is effectively improved
The testing efficiency of radio frequency printed board, reduces the waste of manpower and material resources.
Brief description
Fig. 1 test device of the present invention schematic diagram；Wherein, 1 is radio frequency printed board to be measured, and 2 is the base installing rf probe
Seat, 3 is the pedestal installing printed board, and 4 is the rotary joint of the pedestal connecting and installing rf probe and the pedestal installing printed board,
5 is the elastic device of the pedestal connecting and installing rf probe and the pedestal installing printed board, and 6 is rf probe.
Specific embodiment
The test device schematic diagram of the present invention is as shown in Figure 1.The pedestal 2 installing rf probe passes through rotary joint 4 and bullet
Property device 5 be assemblied in the two ends of the pedestal 3 installing printed board, make pedestal 2 be provided simultaneously with rotatable lift and can automatic impaction
Function, installs the installation offer positioning action that can design 4 root posts on printed board pedestal 3 for printed board, it is to avoid adjust print manually
The position of making sheet；Rf probe 6 is installed on the base 2, has elasticity so that the prevention at radio-frequency port of probe and printed board can be good
Contact.Two ends only need to be lifted during test the pedestal 2 with elastic radio frequency probe is installed, put in the middle of the pedestal 3 installing printed board
Put radio frequency printed board 1 to be measured can be tested.
The concrete testing procedure of radio frequency PCB testing device is:
(1) elastic rf probe 6 is arranged on the pedestal 2 installing rf probe；
(2) elastic device 5 is arranged between pedestal 2 and pedestal 3；
(3) using rotary joint 4, pedestal 2 and pedestal 3 are cascaded；
(4) a certain radio-frequency performance according to tester's printed board of concern, rf probe 6 is connected and tests to corresponding
Instrument；
(5) lift the pedestal 2 at pedestal 3 two ends, place radio frequency printed board 1 to be measured in the middle of pedestal 3；
(6) pedestal 2 of the installation rf probe of loose ends, completes the radio-frequency performance test of radio frequency printed board 1 to be measured；
(7) complete to test, lift the pedestal 2 at two ends, place the printed board to be measured of next block.
