Surface Insulation Resistance (SIR) Testing
Meet demanding miniaturization challenges while ensuring PCB reliability with Element's Surface Insulation Resistance (SIR) Testing. As PCBs become smaller and spacing between their conductive parts decreases, our hands-on experts provide detailed insights into your PCB’s performance under real-world temperature and humidity conditions, helping you validate processes and prevent electrochemical failures. With rapid turnaround times and comprehensive analysis, we help you deliver superior products that meet rigorous reliability standards.
What is Surface Insulation Resistance (SIR) Testing at Element?
Surface insulation resistance (SIR) testing, also referred to as temperature humidity bias (THB) testing, is a test process used to determine if a printed circuit board is likely to fail when exposed to various temperature and humidity conditions.
As PCBs become smaller and the spacing between their conductive parts decreases, they become more susceptible to failure modes caused by surface residues and humidity. Get detailed insights into your PCB's performance with our Surface Insulation Resistance testing, also known as temperature humidity bias (THB) testing. We simulate real-world conditions to identify potential failure modes like conductive anodic filament (CAF) formation and electrochemical migration and validate the effect of new processes on the product’s surface insulation resistance.
