Abstract
The utility model discloses a hermaphroditic connector's survey test panel, it includes that two at least pads, SMA head, resistance and PCB walk the line, one of them pad is walked the line through PCB and is connected all the other pads process grounding with the SMA head. A survey test panel, hermaphroditic connector and test equipment that hermaphroditic connector's testing arrangement includes two foretell hermaphroditic connector. Grounding has been realized passing through to hermaphroditic connector's unsettled PIN by resistance and pad through surveying on the test panel to reduced to insert and decreased the resonance that arouses and crosstalk, increaseed the precision to the electric capability test of nonpolarity connection. The utility model relates to an install and extensively be applicable to integrated circuit test field of being directed at the hermaphroditic connector electric property is tested.
Description
Technical field
This utility model relates to integrated circuit testing field, the test board of a kind of hermaphroditic con and device.
Background technology
Hermaphroditic con: itself does not specify signal pin and ground pin, needs the adapter that user specifies the when of use, such as pogo adapter.
Along with the development of electron trade, various circuit all tend to using integrated mode.Adapter be our electronic engineering technical staff often in contact with a kind of parts.Its effect is the most simple: between two veneers or plate internal circuit, erect the bridge of communication, so that signal circulation, makes the function that circuit realiration is predetermined.When using hermaphroditic con, the quality of hermaphroditic con directly affects the performance of circuit, the most before use it will be clear that and know the performance parameter (including structure, serviceability and classical insulation) of hermaphroditic con itself exactly.At present, when the electric property aspect to hermaphroditic con is tested in the industry, generally tested by design connector test plate, do not process for unsettled pin foot.The pin not processed also is directly grounded, and influences whether to draw the quality of pin foot test, disturbs signal roundtrip inside, can cause big resonance, can become the biggest for crosstalk for Insertion Loss.
Utility model content
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide test board and the device of a kind of hermaphroditic con reducing resonance that Insertion Loss causes and crosstalk.
This utility model be the technical scheme is that the test board of a kind of hermaphroditic con, it is characterized in that: it includes at least two pad, SMA head, resistance and PCB trace, one of them pad is connected with SMA head by PCB trace, and remaining pad is through resistance eutral grounding.
Further, described test board is provided with a Thru line, a Load line, three line lines and an Open line.
This utility model additionally provides the test device of a kind of hermaphroditic con, it includes the test board of two pieces of above-mentioned hermaphroditic cons, hermaphroditic con, SMA connecting line and Network Analyzer, the test board of described two pieces of hermaphroditic cons is divided into test board and lower test board, described upper test board is connected with lower test board by hermaphroditic con, and described upper test board is connected with Network Analyzer by SMA connecting line respectively with lower test plank.
The beneficial effects of the utility model are: the pin vacantly of hermaphroditic con is achieved through resistance eutral grounding by the resistance on test board and pad by this utility model, thus decrease resonance and the crosstalk that Insertion Loss causes, increase the precision of electric performance test to nonpolarity connection.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
Fig. 1 is the circuit diagram of test board one specific embodiment of a kind of hermaphroditic con of the present utility model；
Fig. 2 is the structural representation of the device of a kind of hermaphroditic con of the present utility model.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
Embodiment 1
As it is shown in figure 1, the test board of a kind of hermaphroditic con, it is characterised in that: it includes at least two pad, SMA head resistance and PCB trace, and one of them pad is connected with SMA head by PCB trace, and remaining pad is through resistance eutral grounding.
Wherein said SMA is for being connected with Network Analyzer, and described resistance is adjustable, mates according to the situation of circuit.
Being further used as preferred embodiment, the test board of described hermaphroditic con is provided with a Thru line, a Load line, three line lines and an Open line, and three line lines include line1, line2 and line3.Three groups of data, Thru, Reflect and Match can be calculated during TRL calibration.Thru is exactly the data of Thru line, and Reflect refers to the data of open line, and Match refers to the data of load, line1, line2 and line3 line.Load is directed to the verification of low-frequency range, and high band then verifies with line1, line2, line3, only need to ensure that the highest frequency of each section and the ratio of low-limit frequency are less than 8.The test board making described hermaphroditic con by arranging TRL standard component can be connected with Network Analyzer and carries out TRL calibration, then tests, obtains the classical insulation of adapter.
Embodiment 2
As shown in Figure 2, a kind of test device of hermaphroditic con, it includes the test board of two pieces of above-mentioned hermaphroditic cons, hermaphroditic con 3, SMA connecting line and Network Analyzer and test equipment, the test board of described two pieces of hermaphroditic cons is divided into test board 1 and lower test board 2, described upper test board 1 is connected with lower test board 2 by hermaphroditic con 3, and described upper test board 1 is connected with Network Analyzer by SMA connecting line respectively with lower test plank 2.
Wherein said upper test board 1 is used for making hermaphroditic con 3 be connected with test equipment with lower test board 2 and pad, wherein pad connects one to one with the pin of hermaphroditic con 3, one of them pad is connected with SMA head, remaining pad is connected to ground by resistance respectively, so that the unsettled PIN of hermaphroditic con 3 is connected to ground by resistance, reduce the reflection of signal, thus decrease the resonance on the Insertion Loss of side measured signal pin and crosstalk, increase the precision of electric performance test to nonpolarity connection.
Wherein, Network Analyzer connects through SMA p-wire and is connected with the SMA head on upper test board 1 and lower test board 2, by TRL thereon arrange calibration upper test board 1 and lower test board 2 are entered cabling and SMA impact be calibrated out, each parameter of upper test board 1 and lower test board 2 is carried out TRL calibration, and then test can obtain the performance parameter of hermaphroditic con.
The beneficial effects of the utility model are: the unsettled PIN of hermaphroditic con is achieved through resistance eutral grounding by the resistance on test board and pad by this utility model, thus decrease the resonance and crosstalk that on signal pin, Insertion Loss causes, increase the precision of electric performance test to nonpolarity connection.
It is above preferable enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement on the premise of this utility model spirit, and deformation or the replacement of these equivalents are all contained in the application claim limited range.
