Conformal coating inspection systems

SCH Technologies offer a range of conformal coating inspection systems.

They include:

All of the systems have been tried and tested in our coating services and can be suitable for low, medium, and high level conformal coating production.


Manual conformal coating inspectionSCH offer a range of conformal coating manual inspection systems

Manual inspection of circuit boards after conformal coating application is the main method used by >95% of the electronics manufacturing world.

There are two critical points when considering inspection & finishing and they all relate to creating the optimum environment.

First point is to provide the perfect conditions where an operator can easily inspect conformally coated circuit boards without fatigue to body or eyes. This will provide the highest quality results for the conformal coating process.

Once this is complete the second critical factor is to provide a work space that will keep the operator safe from the harmful effects of solvents if they are used.

Complete these two points and the operator will have the perfect conditions for inspecting conformally coated circuit boards.

SCH Technologies design and manufacture a range of purpose-built, compact, and coordinated UV inspection & finishing booths for conformal coating inspection.

Automated conformal coating inspection (CCAOI)SCH provide Modus conformal coating AOI systems

Automating a conformal coating inspection process can be a difficult process. The coating fluoresces and is transparent allowing the colours of the circuit board below to interfere with the analysis of the image. Link this to a 3D structure and this can be extremely problematic for high speed processing.

It has took a long time to develop AOI systems that can meet these challenges.

However, Modus, a German AOI company has specialised in this area and now provides camera and scanner based technologies which provide a range of solutions for conformal coating Automated Optical Inspection (AOI).

These systems address the IPC standards directly, ensuring that the criteria for inspection is met. The systems use UV LED lighting systems which optimise the image capture and they can address 3D issues using parallax free lens systems for their scanner systems.

Why is conformal coating inspection important?Conformal coating inspection is an important process.

Ultimately, the conformal coating is only as good as how its applied. If you can’t inspect it correctly then its almost impossible to ensure that the quality is good enough.

Inspection of conformal coated circuit boards is a critical process that should be carried out on completion of the finishing process. However, it is often neglected stage of the conformal coating process.

The standards such as IPC A 610 are explicit in their requirements for conformal coating inspection yet few companies actually inspect to that level.
