Are there any established acceptance criteria for contaminants based on Ion Chromatography testing? I've found some references to certain levels for some contaminants but there doesn't seem to be any industry consensus. Any feedback or reference to l

In your situation, the issue is the compatibility of your flux residues and the encapsulant that you choose. First, contact your encapsulant supplier for advice. They've likely been down this road with other customers and may be able so save you som

Hi there - unfortunately, there are no good cleanliness specs available mainly because clealiness requirements are case sensitive - you should talk to Terry Munson at 765-457-8095 - he can definitely give you advice on Ion Chromatography, SIR, ROSE t

Three popular methods: Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25: The ROSE test method is used as a process control tool to detect the presence of bulk ionics. The IPC upper limit is set at 10.0 *g/NaCl/in2. This test is p

ROSE has the advantage in that it does have a specific acceptance criteria (J-STD-001), whereas the IC does not. ROSE allows the test to be run at ambient or at an elevated temp, IC requires the component/board/assembly to be "cooked" for 1 hour @ 8

New to using Ion Chromatography (IC)testing to understand cleanliness of PCB. I've been informed that one method to monitor is to use R/O/I. What is R/O/I?

Thanks for the reply. R/O/I is ROSE / Omegameter / Ionograph which is used as a baseline for Ion Chromatography.

edmaya33, you're correct about what J-STD-001E says, but recognize that the measure that you refer us to in not IC [Ion Chromatography]. It is modified ROSE [Resistivity of Solvent Extract] ... or whatever they call modified ROSE now-a-days

Our Customer had detected tarnished pad on ImAg PCBA and had conducted several SEM-EDX test at the soldermask below some of the chip resistors. High concentration of sulfur was found and it can be significantly reduced after further chemical cleaned
