Viscom's proven S3088 CCI inspection system ensures high-precision conformal coating inspection of printed circuit boards. The system quickly and reliably detects typical defects such as cracks, coating voids, smearing and splashing. Layer thickness and wet coating can also be analyzed. The S3088 CCI now comes standard with an unmatched upper transport clearance of 105 mm, thus providing even more flexibility during final inspection of fully assembled components.

Conformal coating is becoming increasingly important in electronicsmanufacturing. Coating is applied wherever electronic components need tobe protected against damaging environmental influences. This is especiallythe case for safety-relevant applications. The rapid and continueddevelopment in electromobility and autonomous vehicles, as well as thegrowth of wind energy, have made this production step all the moreessential. The insulating effect of conformal coatings responds to the trendtoward miniaturization by allowing the distance between conductor paths tobe reduced.

The inspection process uses white light and special UV LEDs which reliablyreveal defects in UV-sensitive conformal coating. The S3088 CCI's flexibleinspection algorithms can be rapidly adapted to various conformal coatings.Optimal inspection coverage is ensured by means of one orthogonalcamera in combination with four, or optional eight, angled view cameras,which allow for accurate inspection of component sides and gaps betweenpins. With a maximum orthogonal resolution of up to 15 μm/pixel and anangled view resolution of up to 17.5 μm/pixel, the S3088 CCI inspects alltypical defects with 100% reliability — and thanks to the standard four, oroptional eight, side views, inspection results are free of shadowing.

Viscom AG · Carl-Buderus-Str. 9 - 15 · 30455 Hanover, Germanycoatings, such as conformal coatings which are very thin or coatings whichcontain silicone. The system also provides layer thickness measurement(3D spot measurement), nanolayer inspection and wet coating inspection.Additional inspection of selected post-reflow criteria, such as OCR anddisplacement, is also available.

The camera system works with the vVision or EasyPro inspection software,thus offering the same user interface as other AOI systems in the provenS3088 family. Inspection program creation is hence quick and easy. As aresult, traceability concepts, special inspections such as reading labels withdata matrix code (DMC) and other production-relevant features can beimplemented effectively. Moreover the documentation of all process data isguaranteed.
