Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 2, the structural representation of the utility model pcb board pressure resistant testing device first embodiment, this device comprises Hi-pot Tester 10 shown in the figure, first lead, second lead, test needle stand 13, input test pin 11 and output testing needle 12, input test pin 11 and output testing needle 12 are fixed on the test needle stand 13, the output terminal of Hi-pot Tester 10 connects input test pin 11 by first lead, the earth terminal of Hi-pot Tester 10 connects output testing needle 12 by second lead, also comprise capable Test Switchboard 15 and row Test Switchboard 16, row Test Switchboard 15 is electrically connected between the output terminal of input test pin 11 and Hi-pot Tester 10, and row Test Switchboard 16 is electrically connected between the earth terminal of output testing needle 12 and Hi-pot Tester 10.
The two piece conductive pins of input test pin 11 for being arranged in parallel, output testing needle 12 is two conductive pins that are arranged in parallel.Further, input test pin 11 and output testing needle 12 are the conductive pin of metal material.Further, input test pin 11 and output testing needle 12 are copper pin or stainless pin.
See also Fig. 3, in second embodiment of the present utility model, the pcb board pressure resistant testing device also comprises control panel 17 except all technical characterictics that comprise first embodiment, and row Test Switchboard 15 and row Test Switchboard 16 all are fixed on the control panel.
Under the test environment of reality, at first make the anchor clamps of whole plate voltage-withstand test, and assembled formation, as shown in Figure 4.Input test pin 11 and output testing needle 12 are fixed on the test needle stand 13, and the little layout 14 of polylith PCB is combined into PCB justifying 18 before sharp processing.Per two input test pins and two output testing needles carry out voltage-withstand test to a little jigsaw.
Then, to couple together respectively corresponding to the testing needle of Hi-pot Tester output terminal and Hi-pot Tester earth terminal, for each little jigsaw, we can stipulate that the testing needle that is connected with the Hi-pot Tester output terminal belongs to anodal, and the testing needle that is connected with the Hi-pot Tester earth terminal belongs to negative pole.Then, the positive pole that will belong to delegation connects together respectively, and the negative pole that belongs to same row connects together respectively, as shown in Figure 5.Hi-pot Tester output terminal row Test Switchboard K1, K2, the K3 of being electrically connected in parallel, Hi-pot Tester earth terminal row Test Switchboard K4, K5, K6, the K7 of being electrically connected in parallel, form the Test Switchboard matrix with row Test Switchboard and row Test Switchboard, the withstand voltage situation of testing the little layout of each PCB according to the break-make of row switch and row switch.
Then, make an easy control panel in the outside of voltage-withstand test frock, as shown in Figure 6, the opening and closing of the line of control correspondence respectively and corresponding alignment.
In proper testing, capable switch and row switch all on the control panel are all closed, like this, can test whole plate, if little jigsaw voltage-withstand test is bad, just judge by capable switch on the control panel and row switch.
Below, be exemplified below at concrete decision method:
Suppose a PCB who contains 12 little jigsaw (3 row, 4 row) is put in order the plate voltage-withstand test, and suppose that two little jigsaw that the 1st row the 3rd row and the 3rd row the 2nd are listed as exist voltage-withstand test bad, we need determine the position of defective products by stirring switch on the control panel.
Our way is: the row of at first judging defective plate place.Disconnect row switch (walking to the 3rd row from the 1st) successively, switch of every disconnection just restarts Hi-pot Tester one time, test again behind the switch that is disconnected to the 3rd row, and Hi-pot Tester is not reported to the police.This explanation, certain defectiveness plate in the 3rd row.Below, whether row (being 1 row and 2 row here) that need to confirm the front defectiveness plate, at this moment, with the switch closures of 1 row and 2 row, test once more, instrument is still reported to the police, and illustrates the 1st to go and the 2nd go back the defectiveness plate among going.At this moment, disconnect the 3rd row capable switch (disconnect the 2nd row here earlier, disconnect the 1st row again) before successively, test again behind the switch that is disconnected to the 1st row, defective disappears, and also defectiveness plate of the 1st row is described, at this moment, whether need to judge between the 1st row and the 3rd row defectiveness plate.To test behind the 2nd row switch closure, Hi-pot Tester is not reported to the police, and illustrating in the 2nd row does not have the defective plate, and the defective plate is locked in the 3rd row and the 1st row.
Next, judge the row of defective plate correspondence.In this example, locked behavior the 1st row and the 3rd row at defective plate place, below, the row of judgement defective correspondence.The switch of at first closed the 1st row (other row switch disconnects, and the row switch is all closed) judges that with above-mentioned same method defective plate the corresponding the 1st goes the row at place.Then, the switch of closed the 3rd row (other row switch disconnects, and the row switch is all closed) judges that with above-mentioned same method defective plate the corresponding the 3rd goes the row at place.
Can judge accurately that like this, soon the defective plate is positioned at the 1st row the 3rd row and the 3rd row the 2nd row.
In this explanation, just sketch the whole plate voltage-withstand test principle that contains 12 little jigsaw (3 row, 4 row), need use 7 switches.If the whole plate that contains 49 little jigsaw (7 row, 7 row) is carried out voltage-withstand test, then need 14 switches, in actual production, it is very low the bad probability of voltage-withstand test to occur, usually far below 1%.So this method though need artificial judgment, still is greatly to have improved voltage-withstand test efficient.
The whole plate voltage-withstand test that contains 12 little jigsaw has only been introduced in this explanation, if the little jigsaw number that contains is many more, testing efficiency is high more.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
