Typically, PAL utilizes IPC testing methods when analyzing circuit boards via IC. However, we can use other approved methods to accomodate your needs, such as Delphi's or GE's specification. What is Ion Chromatography?
Ion chromatography (IC) is a method of analyzing solutions containing components that have an ionic charge. It is the method of choice for analyzing process residues and addressing cleanliness due to its separating and quantifying capacity compared to the traditional Omegameter test. Below is a list of ionic components analyzed by PAL.

Anions: F, Cl, NO2, Br, NO3, PO4, and SO4
Cations: Li, Na, NH4, K, Mg, and Ca
Organic Acids: Succinic, Formic, Acetic, Maleic, Oxalic, and Methane Sulfonic

IPC-TM-650: Ionic Analysis Methodologies

2.3.25 Detection and Measurement of Ionizable Surface Contaminates by Resistivity of Solvent Extract (ROSE)
This method is utilized primarily as a control tool for the inspection of printed wiring boards (PWB's) and assemblies to determine if they meet the user's performance specification/s.


2.3.25.1 Ionic Cleanliness of Bare PWB's
The purpose of this method is to establish the total extractable ionic content found within or upon the surface of PWB's. This method was developed for purposes of process control and results are expressed in sodium chloride equivalents.


2.3.28 Ionic Analysis of Circuit Boards, Ion Chromatography (IC) Method
This method is used to characterize anion, cation, and/or organic acid residues using ion chromatography.


2.3.28.1 Ionic Analysis of Fluxes and Pastes, Ion Chromatography (IC) Method
This method is used to characterize anion and/or organic acid components within fluxes and pastes using ion chromatography.


Continuous Monitoring Program
Our continuous monitoring program allows the client to obtain a large picture of the production process over time. A detailed report is completed upon each analysis and a monthly summary can be generated with the clients request. This program has no limits and can be tailored to meet individual needs.
