ionograph testing | 26 July, 1999

any advice on ionograph testing in the 1 microgram/cm^2 for small devices. We have a old Alpha 500 series machine that is dead but ALpha doesn't service this vintage machine.Any other way to perform this test, or a third party vendors to service this machine, or other manufacturers equipment that can be recommended to perform this tests. Our parts are small less than a 1/4" square and we don't need a SMT sized PCB ionograpgh tester. thanks

Aqueous Technologies manufactures the Zero-Ion ionic contamination tester. The Zero-Ion utilizes dynamic-based technology and has been assigned the highest equivalency value by the NAWC. It is among the most sensitive of all of the military-approved testers. As a rule, dynamic based system are more sensitive than static based systems.

Test cells are available in a variety of sizes including small sizes like 12" x 12" (or smaller custom sizes). The Zero-Ion sells for under $ 10K.

Other manufacturers include Westek (ICOM 5000), Alpha Metals (Ionograph / Omegameter).

You might find a used ionograph out there that meets your requirements. Can your board fab help you?

Good luck
