Our Analytical Methods

Foresite uses a wide range of analytical methods to identify specific residues on the surfaces of electronics..


Commonly Used Residue Analytical Methods

Ion Chromatography

From the beginning, Foresite has used ion chromatography (IC) as a critical tool in our residue-related failure analysis, detecting both anions and cations.



FT-IR Spectroscopy

This analytical method characterizes organic and inorganic substances that could have a negative impact on your product.



Electron Microscopy (SEM/EDS)

Microscopic analysis allows for in-depth analysis of the inner layers of PCBs, PCBAs, and components, catching weaknesses that are almost impossible to pinpoint.



X-ray Fluorescence

XRF is a quick, non-destructive, analytical technique used to determine the elemental composition of a material or mass. Another primary use of XRF, which Foresite performs for numerous clients, is to screen and verify that circuit boards, components and assemblies  are compliant to RoHS (Restriction of Hazardous Substances) initiatives.
