Description

Test board

Technical field

The utility model relates to a kind of test board, but particularly relates to a kind of utility model of test board of test socket pin.

Background technology

In the middle of the manufacture process of motherboard, whether each part of motherboard all needs test in advance normal, avoids the problem that just takes place after shipment, and causes fabricator's heavy losses.

In the middle of prior art, when whether the slot of wanting the Test Host plate or connector can operate as normal, for example whether free weldering, rosin joint of test, open circuit, during the similar abnormal case of short circuit or other, normally memory module or PCI adapter etc. are actual will to be come slot is tested practically in the module of this slot work by inserting.But this test mode is owing to need to use physical storage module or PCI adapter, and therefore required cost is higher.And when inserting memory module or PCI adapter, which pin that also is difficult for judging slot or connector has problem.Therefore this test mode has many inconvenience for the fabricator.

In view of this, the problem that is necessary to provide a kind of novel test board to solve in the prior art and is taken place.

The utility model content

Fundamental purpose of the present utility model is that a kind of test board is being provided, but it has the test socket functions of pins.

For reaching above-mentioned purpose, test board of the present utility model is in order to insert the slot on the motherboard, with a plurality of pins of test socket.A plurality of pins are to cooperate the circuit layout of motherboard to constitute.Test board comprises circuit board, a plurality of electrical inserted terminal and a plurality of portion that electrically conducts.A plurality of electrical inserted terminals are printed on the circuit board, in order to electrically connect a plurality of pins of slot.A plurality of portions of electrically conducting are connected to each other with a plurality of electrical inserted terminals respectively.The cabling of a plurality of portions that electrically conduct is in order to cooperate the circuit layout of motherboard, for a plurality of pins of test.After wherein test board inserts slot, testing whether conducting, and judge further whether a plurality of pins of slot weld normally by input test signal.

Test board of the present utility model does not need to use physical storage module or PCI adapter, and cost is low.And which pin that can judge slot or connector easily has problem, for the user facilitates.

Because the utility model structure is novel, can provide on the industry and utilize, and truly have the enhancement effect, so apply for utility model patent in accordance with the law.

Embodiment

For above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, cited below particularlyly go out specific embodiment of the utility model, and cooperate appended accompanying drawing, be described in detail below.

Below please in the lump with reference to figure 1 and Fig. 2 about the relevant synoptic diagram of the utility model test board with slot, wherein Fig. 1 is installed on the synoptic diagram of slot for test board of the present utility model, Fig. 2 is the synoptic diagram of the circuit layout of motherboard of the present utility model.

Whether test board 10 of the present utility model is in order to the slot on the Test Host plate 1 20, normal to judge its a plurality of pin 21.In the present embodiment, slot 20 is to be used for dual-inline memory module (Dual Inline MemoryModule, slot DIMM) are that example describes, but the utility model is not as limit with a kind of.Slot 20 has a plurality of pins 21, in order to electrically connect with memory module.When slot 20 was installed on the motherboard 1, a plurality of pins 21 were welded in the solder joint on the motherboard 1, therefore needed to cooperate the circuit layout mode of solder joint on the motherboard 1.Circuit layout on the motherboard 1 be a chrysanthemum chain (Daisy Chain) circuit layout, but the utility model is not as limit promptly as shown in Figure 2 in the present embodiment.Because the mode of chrysanthemum chain circuit layout is extensive use of in the application by the general circuit layout, so do not repeat them here its principle.

Test board 10 comprises circuit board 11, a plurality of electrical inserted terminal 12 and a plurality of portion 13 that electrically conducts.Circuit board 11 is a printed circuit board (PCB), in order to print a plurality of electrical inserted terminals 12.A plurality of electrical inserted terminals 12 are a plurality of golden fingers, and when test board 10 inserted slot 20, a plurality of electrical inserted terminals 12 were in order to electrically connect a plurality of pins 21.A plurality of portions 13 that electrically conduct are made by a plurality of sheet metal plate, in order to print or to be attached on the circuit board 11.A plurality of portions 13 that electrically conduct are connected in twos alternately with a plurality of electrical inserted terminals 12.A plurality of portions 13 that electrically conduct cooperate a plurality of pins 21 with the cabling mode of a plurality of electrical inserted terminals 12, that is cooperate the circuit layout that is welded on the motherboard 1.Thus, after test board 10 inserts slot 20, can be connected in series to form a complete loop with a plurality of pins 21.

For example, be example with general dimm socket 20, it has 240 pins 21.Therefore the single face of circuit board 11 promptly has 60 portions 13 that electrically conduct, to cooperate 120 electrical inserted terminals 12,120 pins 21 that electrically conduct.Thus, can test by 10 pairs of all pins 21 of two-sided test board.That is make the starting point input test signal, and last pin 21 is considered as terminal point to have judged whether the test signal transmission with first pin 21.The mode of carrying out test relevant for test board 10 has detailed description in the back.

Please refer to the synoptic diagram that Fig. 3 is connected with the pin of slot about test board of the present utility model.

Figure 3 shows that example, the 13a of the portion that electrically conducts on the test board 10 connects electrical inserted terminal 12a and electrical inserted terminal 12b; The portion 13b of electrically conducting connects electrical inserted terminal 12c and electrical inserted terminal 12d; The portion 13c of electrically conducting connects electrical inserted terminal 12e and electrical inserted terminal 12f.Electrically inserted

terminal

12a, 12b, 12c, 12d, 12e and 12f electrically connect

21a, 21b, 21c, 21d, 21e and 21f more respectively.And because the circuit layout on the motherboard 1, so pin 21b links to each other with pin 21c, pin 21d links to each other with pin 21e again.

In the time will testing, measurement jig (figure does not show) is about to test signal input pin 21a, and whether test receives test signal at pin 21f place again.If receive test signal, but can determine that each inter-module electrically connects the loop that has formed conducting.Therefore a plurality of pins 21 must weld normally.

If arbitrary pin 21 failure weldings are wherein arranged, test signal just can not be transmitted smoothly.In the case, can utilize the portion of electrically conducting 13 to advance the rank testing process again.

Measurement jig is after the test signal input, connects the portion 13 that electrically conducts wherein again, to judge whether conducting of test signal.Thus, can accurately learn which pin 21 failure weldings.

For example, suppose pin 21b failure welding, behind pin 21a input test signal, promptly can't form normally.This moment, measurement jig but can record test signal at the portion 13a place that electrically conducts, and therefore can judge is that pin 21b has unusual condition.By above-mentioned method, the flow process that can advance the rank test apace is correctly to judge the unusual place of slot 20.

To sum up institute is old, and no matter the utility model everywhere all shows it totally different in the feature of known technology with regard to purpose, means and effect, earnestly asks the auditor to perceive, and grants quasi patent early, makes Jiahui society, and the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for convenience of explanation, the utility model interest field required for protection should be as the criterion so that claims scope is described certainly, but not only limits to the foregoing description.
