Embodiment
Main conception of the present invention is with the test combination of complexity, deducts the part of repeated test earlier, simplifies the number of times of test again in the mode of distinguishing group, is to guarantee that with minimum testing time all leads are mutually insulated each other.
Please refer to Fig. 1, it illustrates and is the process flow diagram according to the insulation impedance detecting method of a preferred embodiment of the present invention.At first shown in step 201,, define 2 to M bar lead to be measured
n＜M≤2
N+1, and n is positive integer, and the n+1 representative test M bar lead required testing time that insulate each other.And then shown in step 203, it is immediate 2 that M bar lead is divided into number of lead wires in regular turn
iIndividual group, the initial value of i is 1, and the number of lead wires of each group is respectively N1 and N2, and N1 〉=N2.Then shown in step 205, with 2
iBe numbered the mutual short circuit of lead of odd number group in the individual group, and will be numbered the mutual short circuit of lead of even number group.
Then shown in step 207, measure the lead and the lead of the even number group after the short circuit of the odd number group after the short circuit, its two whether insulate, if not, then representing has short circuit to take place between M bar lead, needs to finish to test.Then shown in step 209,, whether then judge i, if not, then represent M bar lead to survey and finish less than n+1 if above-mentioned insulation impedance meets the requirements, and mutually insulated all each other, test can be finished.And then shown in step 211, if i less than n+1, then increases progressively 1 with i.
Then shown in step 213, it is immediate 2 that M bar lead is divided into number of lead wires in regular turn
iIndividual group, and the number of lead wires of each group is respectively N1, N2 ... N2
i, and N1 〉=N2 〉=... 〉=N2
iEnter step 205 at last again, and finish the insulation impedance test of M bar lead according to aforementioned correlation step.
Please refer to Fig. 2, it illustrates is the permutation and combination figure of 24 leads.Article 24, the permutation and combination of lead has 276 kinds as shown in Figure 2, and insulation impedance detecting method of the present invention utilizes minimum testing time promptly to finish 276 kinds above-mentioned permutation and combination, to guarantee that between 24 leads be mutually insulated.For instance, if number of lead wires M=24, then 2
n＜24≤2
N+1, therefore and n+1=5 utilizes 24 leads of insulation impedance detecting method test of the present invention mutually insulated whether each other, only needs can all test for 5 times to finish.
When measuring for the 1st time, need 24 leads are divided into 2
iIndividual group, and i=1.Therefore, 24 leads are divided into the 1st group and the 2nd group.The 1st group comprises the 1st～the 12nd lead, and the 2nd group comprises the 13rd～the 24th lead.With the 1st in the 1st group～the 12nd the mutual short circuit of lead and with the 13rd in the 2nd group～the 24th the mutual short circuit of lead.And test insulation impedance value between the 1st group and the 2nd group.If it is mutually insulated that measured insulation impedance value is then represented the 1st group and the 2nd group greater than 100M Ω.That is represent the lead of each permutation and combination of zone in 101, be mutually insulated to each other.
When measuring for the 2nd time, i=2.Therefore, 24 leads are divided into the 1st group, the 2nd group, the 3rd group and the 4th group.The 1st group comprises the 1st～the 6th lead, and the 2nd group comprises the 7th～the 12nd lead, and the 3rd group comprises the 13rd～the 18th lead, and the 4th group comprises the 19th～the 24th lead.With the mutual short circuit of all leads in the 1st group and the 3rd group, and with the mutual short circuit of all leads in the 2nd group and the 4th group.And measurement insulation impedance value between the two.If it is mutually insulateds that measured insulation impedance value is then represented both greater than 100M Ω.That is represent the lead of each permutation and combination of zone in 103, be mutually insulated to each other.
By that analogy, after the 3rd measurement, the 4th measurement and the 5th measurement finish, can learn that 24 leads insulate each other.That is represent the lead of zone 105, zone 107 and zone each permutation and combination in 109, be mutually insulated to each other.
In addition, the present invention is applied on the film circuit board, because film circuit board itself has generation of static electricity, so the insulation impedance value is limited at least the scope of experiment greater than 100M Ω.In addition, the number of lead wires of test also can for other for example be 25 or 34 leads all can, and this film circuit board also to can be applicable to for example be on the keyboards such as digitizing personal assistant (PDA), mobile phone, notebook computer.
The disclosed a kind of insulation impedance detecting method of the above embodiment of the present invention, test combination with complexity, the part of deduction repeated test is earlier simplified the number of times of test again in the mode of distinguishing group, be to test out between all leads each other insulation impedance effectively with minimum testing time.In quality management (Quality Control), can reduce manpower and improve product test efficient, and then make product experimentally use more conveniently in volume production or research and development.
In sum; though the present invention discloses as above with a preferred embodiment; so it is not to be used to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking appended the claim scope person of defining.
