Embodiment
Fig. 1 is the detection schematic diagram of the pin welding condition detection apparatus of the utility model one preferred embodiment.Fig. 2 is the distribution schematic diagram that the pin of the utility model one preferred embodiment welds the switching part of condition detection apparatus.Please refer to Fig. 1 and Fig. 2.In the present embodiment, pin welding condition detection apparatus 1 is used to detect the welding situation of a plurality of pins 21 of slot 2.At this, slot 2 is that example describes with the cpu socket with 989 pins.Yet the utility model is not done any qualification to this.
In the present embodiment, pin welding condition detection apparatus 1 comprises a plurality of switching part 10, a plurality of probe 11, at least one resistance 12, detection piece 13 and indication piece 14.The corresponding one by one setting of pin 21 of switching part 10 and slot 2, probe 11 connects switching part 10 respectively, and when detecting, probe 11 also connects one to one with pin 21 respectively.That is, switching part 10, probe 11 equate with the number of pin 21.
In the present embodiment, during detection, each switching part 10 is connected to each pin 21 of slot 2 respectively through probe 11, and therefore, the situation of each switching part 10 can reflect the welding situation of corresponding pin 21.That is, in the present embodiment, each switching part 10 can be simulated corresponding pin 21.At this; Switching part 10 is also corresponding identical with the type of pin 21; As shown in Figure 2, it can comprise ground connection (GND) switching part, 1.5 volts of voltage switching parts, bus termination voltage (+VTT_CPU) switching part, core voltage (+VCORE) switching part, 1.8 volts of voltage switching parts and empty pin (NC) switching part.Yet the utility model is not done any qualification to this, and it can be done change according to the type of the slot that is detected.
In addition, in the present embodiment, owing to adopted probe 11 to connect the corresponding pin 21 of switching part 10 and slot 2, therefore, it can have excellent contact property, and can improve the serviceable life of whole pin welding condition detection apparatus 1.When probe 11 damages, also only need change corresponding probe 11, and need not change whole pin welding condition detection apparatus 1, to practice thrift maintenance cost.
In the present embodiment, per two switching parts 10 electrically connect each other, and both have different potential.At this; Because the number of the pin 21 of the corresponding slot 2 of the number of switching part 10 is an odd number; Therefore, as shown in Figure 1, certain two switching part 10 (being arranged in the switching part 10 of both sides among Fig. 1) can be connected to a switching part 10 (Fig. 1 is positioned at middle switching part 10) with high potential jointly.Yet the utility model is not done any qualification to this.In other embodiments, wherein some switching parts also can be connected to power supply unit (figure does not show) or grounding parts (figure does not show) separately.
In the present embodiment, resistance 12 connects per two switching parts 10 that electrically connect each other, so that these two switching parts 10 that electrically connect each other form a test loop with the resistance 12 of corresponding connection.Because the number of the pin 21 of slot 2 is an odd number, therefore, the number that the number of resistance 12 can be pin 21 adds 1 again divided by 2.At this, be 495.Yet the utility model is not done any qualification to this.
In the present embodiment, the resistance value of each resistance 12 can equate, for example, can be 56 ohm.Yet the utility model is not done any qualification to this.In other embodiments, the resistance value of each resistance 12 can have different values.In addition, be the situation of avoiding judging by accident, also for obtaining preferable anti-interference, resistance 12 is preferably has bigger resistance value simultaneously.
In the present embodiment, when two pins, 21 welding of the correspondence of slot 2 just often, the resistance value of the test loop that it is corresponding is the resistance value of resistance 12.As shown in Figure 1, the resistance value of the test loops that formed by two resistance 12 parallel connection should be the value of two resistance 12 parallel connections.Yet the utility model is not done any qualification to this.When reality is used, also can in test loop, set up the element that other has resistance value.
In addition, in the present embodiment, switching part 10 and resistance 12 can be packaged into the form of a double-sided circuit board component.Wherein, the one side of facing slot 2 is provided with switching part 10, and corresponding linking probe 11, and relative another side can be provided with resistance 12.Yet the utility model is not done any qualification to this.
In the present embodiment, detection piece 13 for example can be computer, and it connects switching part 10.Yet the utility model is not done any qualification to this.Can store trace routine in the detection piece 13, be used to detect the resistance value of each test loop, and compare with predetermined value.Particularly; Detection piece 13 can come according to the height of each switching part 10 current potentials automatically each test loop to be supplied power; Detect the resistance value of each test loop simultaneously, and detection resistance value that obtains and the predetermined value that is stored in it are compared, obtain the welding situation of corresponding pin.In the present embodiment, two pins 21 that predetermined value is the correspondence of slot 2 are under the normal situation of welding, the due resistance value of test loop.At this, can correspond to the resistance value of resistance 12, as shown in Figure 1 in addition, other has the predetermined value of a test loop to be the value of the parallel connection of two resistance 12.
