Expansion of the Multi Line platform with high-resolution color camera module and oblique view cameras for the inspection of protective coatings (CCI)
Protective coatings ensure the reliability of electronic assemblies. Errors in the coating can therefore have serious consequences for their function. Malfunctions or field failures cannot be tolerated, especially when used under changing climatic conditions and in safety-relevant automotive, military, avionics and telecommunications applications. Painting defects and deviations from the painting plan can now be detected automatically and reliably with the new CCI inspection system from GOEPEL electronic – for the first time simultaneously on both sides, which significantly reduces the inspection time in production.
The new Multi Line CCI for conformal coating inspection (CCI) extends the Multi Line machine platform from GOEPEL electronic. This fully automatic CCI system can inspect both from above and optionally from below. For example, dip-coated assemblies can be inspected on both sides simultaneously without having to turn the assembly over. Fully automatic return of the assemblies below the inspection level is also possible. The CCI camera module of the Multi Line CCI is equipped with a high-resolution color camera (resolution 8 µm/17 µm), telecentric optics and high-power UV LEDs for illumination from several directions with a wavelength of 365 nm. The camera module can also be equipped with four or eight angled-view cameras in order to inspect connector pins reliably from multiple viewing directions.
The upper component clearance is a comfortable 120 mm; assemblies weighing up to 15 kg can be transported. Inspection can therefore also be carried out directly in product carriers. For seamless protective coating inspection, fluorescent coatings are illuminated by the UV LEDs in the Multi Line CCI. In conjunction with the color camera, the high-resolution, telecentric optics provide high-contrast images and enable inspection within seconds.
Programming the CCI inspection is designed to be extremely user-friendly: The system is set up within a few minutes using CAD data and painting plans. Both the painted and unpainted areas of the assembly are inspected. The new system is based on the Multi Line platform with an operating system and housing optimized for professional production applications. The tried-and-tested Pilot 7.1 operating software now features the new CCI inspection function. This covers all requirements for an all-encompassing protective coating inspection and also enables the import of a painting plan. The overarching hardware and software platform character enables flexible employee scheduling and optimizes the exchange of knowledge within the company, as the AOI is operated centrally and almost identically on all Multi Line systems, without the need for extensive training.
