At 'productronica', the books 'Beschichtungsstoffe für die Elektronik. Part 1 + 2' by Dr. Manfred Suppa (Lackwerke Peters) will be presented. The 1,300-page two-part book will be published by Leuze-Verlag in 2024. We interviewed Dr. Suppa.
What has changed compared to its predecessor from 2010?
It was time for a new edition. 13 years is almost an eternity in our industry. A lot has happened in terms of technology. The first book also dealt exclusively with conformal coatings, i.e. protective coatings for the electronics of certain assemblies. Over the years, the area of potting compounds has grown considerably and moved more into the electronics of assemblies, especially transparent potting compounds, for example for LEDs. In general, the requirements for assemblies have increased, for example in the high-voltage area of e-mobility and miniaturization. There is a great need for more in-depth information about coating materials and how coatings and potting compounds work.
How do modern products differ from earlier coating materials?
The first coating materials were generally single-component protective coatings, often physically drying, i.e. technologically simple. In the meantime, UV-curing coatings and 2K coatings have been developed. Their chemistry is more complex. Handling them requires more know-how.
How much has this changed the coatings?
As expected, the properties have improved significantly in terms of temperature resistance, thermal shock resistance and compliance with insulation limits under moisture. I explain all this in detail in the two books. Visitors to the trade fair can take a first look.
