Description
Technical field
The utility model relates to the anti-ion migration test technical field of (being called for short CAF), specifically is a kind of CAF multichannel measuring system.
Background technology
Development along with miniaturization of electronic products, in high-density multi-layered printed wiring board, layer with layer, distance between the Kong Yukong, between line and the hole is more and more littler, these small distances are easy to make electronic product in use because of inner generation copper ion migration circuit malfunction to take place, and have reduced reliability of products.For fear of the generation of ion migration, need checking sheet material, production technology and design safety distance, need carry out anti-ion migration test (being called for short the CAF test).In order to obtain reliable result, test needs to use a large amount of samples, thereby need a large amount of measurements, CAF measuring equipment in the market, all be subjected to measuring the restriction of passage, 56 passages, 126 passages, 256 passages can only be measured, multi-channel measurement more can't be satisfied to improve the requirement of efficiency of measurement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, CAF multichannel measuring system of being suitable for significantly improving efficiency of measurement.
For solving the problems of the technologies described above, the utility model provides a kind of CAF multichannel measuring system, and it comprises: be used for connecting respectively a plurality of high-density multi-layered printed wiring boards that place constant temperature humidity chamber the sample stube cable, organize the sample stube cable with the hyperchannel conversion equipment that links to each other of sample stube cable of grouping, being used for of linking to each other with the hyperchannel conversion equipment by each each high-density multi-layered printed wiring board carried out the computing machine that the Insulation Resistance Tester of grouping mea-sure, being used to of linking to each other with this Insulation Resistance Tester realize that measurement data is stored; The hyperchannel conversion equipment links to each other with described Insulation Resistance Tester by measuring cable B.Be connected with on the hyperchannel conversion equipment and be used for the bias voltage access device of input measurement with bias voltage.
Good effect of the present utility model: in the CAF multichannel measuring system of the present utility model, the cable that the hyperchannel conversion equipment will connect sample (being a plurality of high-density multi-layered printed wiring boards) divides into groups to connect, and uses Insulation Resistance Tester to carry out grouping mea-sure then.Device of the present utility model can increase the measurement passage greatly, has solved the problems of measurement in various product test, makes the sample number of single test can increase a lot, has reduced experimentation cost.This device is measured the conversion except that providing, and measurement clearance can be inserted current-limiting resistance, adds bias voltage for the experimental network in the sample, satisfies the growth conditions of ion migration.
