SPI InspectionSolder Paste Inspection (SPI) is an automated 3D optical inspection performed immediately after the solder paste is printed onto the PCB. It precisely measures the volume, height, and alignment of the paste to detect printing defects early. This proactive check prevents soldering issues in subsequent stages, significantly improving production yield and reducing rework. 

3D Solder Paste Inspection (SPI)

X-Ray InspectionX-Ray Inspection is a non-destructive test method used to examine hidden solder connections, such as those under BGA and QFN components. It effectively identifies defects like solder voids, bridges, and misalignment that are invisible to the naked eye, ensuring the structural and electrical integrity of complex PCB assemblies.

Characterization for materials used in medical devices – an analysis of a material’s composition, purity, uniformity, sterilant residuals and extractables – is an essential step to verify their suitability for human body contact, thus should not be missed out throughout the product life cycle.  Following the enforcement ofRoHS2 in the European Union, which restricts the use of specified hazardous substances in electrical and electronic equipment, and medical devices are now added to the scope of the Directive and have to be verified asRoHS-compliant.  The chemical laboratory at STC is equipped with the most advanced testing equipment; our team of experts can perform material characterization and RoHS analysis with a wide range of testing methods. We can help manufacturers identify the appropriate testing program based on the intended use of a device and material, and its expected nature of contact with the human body.
