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

Hi, We will run a no-clean wave solder process to assemble TV boards. What about incorporating a ROSE Test equipment (Ionograph, zero-ion, Omega Meter) in the process? Is it recommended, helpful or unnecessary? I�ve read about the use and limits of

A fairly painless method for monitoring cleanliness is Resistivity Of Solvent Extract [ROSE]. Equipment is: * Omegameter * Ionograph * Ion Chaser [Zero-Ion] Anyone who desires to use an Resistivity Of Solvent Extract tester should read EMPF repor

Your Ionograph and Zero-ion Values are set by you. There is no raw pass of fail criteria only the limits you set up. Ionograph is great for bare board resistivity (salt) test just as a pass fail for incoming inspection but this is all per your facto

Hi, Is there a standard expiry date for a ROSE Test Instrument Like Ionographs, Omega Meters, Zero-Ion etc.? How can I verify if my OmegaMeter 500 which is almost 20 years old is providing me reliable data during testing? Note that the equipment is

This may sound dopey, but it may be the answer to your question. ROSE testers from different suppliers produce different results. Look at MIL-STD 2000. Based on Table VII, you find the following upper control limits (micrograms NaCl / sq. in.): * M

When carry out the contamination test,do we measure for Chlorides on water soluble and No-clean fluxes? 1) What is the equivalent factor for machines developed to test the board cleanliness, Omega-meter vs Ionograph vs Zero-ion. 2) What values do we

Both are equally efficient process control tools. Neither is particularly effective in testing ionic contamination. The best way to sell your customer on allowing you to do this is to show them that you understand the WHOLE process and are able

Hi GS, Just a clarification� No-clean does NOT equal no ions. It equals less ions (at best). Automatic R.O.S.E (Resistivity Of Solvent Extract) testers are commonly used to detect ionic contamination from no-clean applications. Your comment rega

You should specify the level of res based on the effect of the res on the end-use of the product. J-STD-001 defines cleanliness requirements for ALL flux types, including water soluble and no-clean that you mention. 1 There is no equivalency betwee
