vp980 - cd4007 testing Reply

Fastah Hi I just repairing some old scope and suspect one cd4007 was failed but testing with vp-980 say chip was ok. Is this test realy reliable and complete? I don"t have spare chip for trying. Can you recheck testing options for this chip in software? Thank you Go back list [ Posted:2009-09-22 07:44:54 ]

lxx Our test only can test chip"s logic. If chip has bad in quality, such as speed, it can not test. Go back list [ Posted:2009-09-22 08:47:56 ]

Fastah About testing dram chips... this is basic five type of dram chips: 4164 (64k x 1bit), 4464 (64k x 4bit), 41256 (256k x 1bit), 44256 (256k x 4bit) and 511000 (1M x 1bit)... if you make some "generic" algorithm for testing various manufacturers and speeds this will be great feature... Please see what you can do... I have 5-6 datasheets and can send all to your mail.... Thanks again Go back list [ Posted:2009-09-22 23:47:47 ]
