Quality Assurance SMT Manufacturing.

Digital Optical Comparator system for PCB-A Factory. The system photographs the the PCB components including the soldering of the components and compares it to a digital golden sample. By caparing the 2 it identifies incorrect component placments, missing components, missaligned components and even defective soldering. source

Electronic data aids inspection in PCB Assembly

Contract manufacturers create and store a lot of electronic information in the process of manufacturing printed circuit board assemblies. This video shows how that information can be leveraged to improve inspection and quality control throughout production. source

AOI (Automatic Optical Inspection)-PCBA Quality Control-High Quality SMD Assembly China-SMT PCBA.mp4 Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used in the manufacturing process because […]
