Military and most commercial standards requires post-soldered boards to measure less than 10 �g/in of NaCl (14 when using an Omegameter, 20 on a Ionagraph, and 37 on a Zero-Ion). As Dave stated, 6.5 �g/in of NaCl is called out in Mil-P-55110 for ba

Q1: Will the ion chromatography be able to identify and quantify the contaminant? A1: Yes, it will identify and quantify the amount of contaminant. Obviously this is very useful in troubleshooting the source of the contaminant. [The only problem fo

First, welcome to your new job. Second, IPC-TM-650 2.6.14 is only loosely an �Ionic Contamination (Electromigration) Test�. * Electromigration Test, IPC TM 650 2.6.14, 2.6.14.1 * Ion Chromatography for Ionic Cleanliness, IPC TM 650 2.3.28 Third, I

The "Rose" test is a process control tool because it is cheap and easy to use. It has it's problems; but, it is generally agreed to be the best tool available for this purpose. All others are much more expensive and time consuming to run every day.

| I need a memory jog. What is the term for the growth of conductive contamination after a board is in storage or field? | There are several different mechanisms which can cause this. In reality, ionic contamination is the root cause for many of the

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
