Chiakl Ion Chromatography has been perfectly described by Dave, but here are a couple of extra considerations: Ion Chromatography will tell you precisely what is present on the surface of your board/assembly but it will not tell you whether it will b

An ionic contamination tester should meet industrial cleanliness specifications including MIL-STD-2000A, MIL-P-28809, J-STD-001 and Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25

You should refer to the IPC-J-STD001B and IPC-TM-650, they will give you good recommendations. Also, we do new reliability test systems and if you can give me your address and e-mail, I will send you some more info. Regards, Graham Naisbitt | looking

�What does 5 micrograms of chloride mean to me?� * With SIR testing, you can show no detrimental leakage currents under humid conditions, no corrosion, no metal migration, which are the big factors in figuring out electrochemical reliability. People

Hi: I am wondering what others are doing that use a Static Ionic contaminate test (e.g. Ionograph/Alphametals) in relation to time. Our Ionograph has the option of setting a test time, or setting it to auto-terminate when there is no change in resis
