6 FAQs about [Requirements for conformal coating for photovoltaic inverters]

What is the best standard for a conformal coating?

For example, someone who manufactures printed circuit assemblies (PCAs) for standard commercial usage, will be best served using the IPC-610 standard for their conformal coating. However, NASA standards are far more applicable to aerospace projects.

What are the IPC standards for conformal coating?

The two most important IPC standards for conformal coating are: IPC A 610 Acceptability of Electronic Assemblies Standard – It is currently the most widely used IPC-standard for consumer and high reliability printed wiring assemblies. It contains valuable, but limited, criteria for conformal coating applications.

What standards are available for the energy rating of PV modules?

Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.

What is the ul746e conformal coating standard?

The UL746E Conformal Coating Standard comprises a series of dielectric tests that measure the coating’s insulation properties following environmental stress, as well as its flame retardancy. The IPC-CC-830 standard was created by the Institute for Printed Circuits (IPC) to replace the MIL-I-46058C Standard, which was declared inactive in 1998.

How thick is a conformal coating?

Typical coating thickness ranges from 12.5 μm [0.49 mil] to 200 μm [7.9 mil]. Processing characteristics and curing mechanisms are dependent on the coating chemistries used. The desired performance characteristics of a conformal coating depend on the application and should be considered when selecting coating materials and coating processes.

What are the different types of conformal coatings?

There are currently eight distinct families of conformal coatings, as designated in the IPC-CC-830C Standard. These comprise acrylic, polyurethane, silicone, epoxy, UV curable, parylene, ultra-thin and styrenated block-copolymer types. The table below summarizes the pros and cons associated with each coating type.
