OPPORTUNITIES: Growing Demand for AOI systems for inspection of IC substrates

The introduction of nanotechnology has triggered the miniaturization and use of high-density PCBs in electronics manufacturing. However, with these advancements, many problems are arising. As the size of the PCB is shrinking, the ball grid array (BGA) gap is also decreasing, which gives rise to various defects in the PCB. Few of these defects include substrate corrosion, material mismatch, solder paste defects, and susceptibility to EMI interference. These defects cannot be precisely identified using manual inspection. Hence, there is a rising demand for the use of AOI systems in the detection of IC substrate defects.

CHALLENGES: Availability of superior inspection technology as the substitute

An AOI system works efficiently while inspecting PCBs where solder joints are visible. However, with the advent of new PCB and IC manufacturing technology such as ball grid array (BGA), where solder joints are not visible, AOI systems are not capable of finding soldering defects. On the other hand, other inspection technology, such as automated x-ray inspection (AXI), can inspect a wide range of assembly defects of PCBs with BGA technology. AXI uses X-rays instead of light imaging to inspect the PCBs. Companies often use AXI to evaluate particularly complex or densely constructed boards.
