It is suggested that automated optical inspection (AOI) competes effectively to fill the in-circuit test gap. AOI adds no unwelcome technologies to the workplace. Its programming and its results are simple and understandable in visual terms. AOI is thus considered high in strength, simplicity and universality. It is expected to grow rapidly, driven by the never ending demand for strong, simple, universal inspection methods.
