Roartis is a manufacturer of high-quality and innovative products for electronics and industrial applications. Roartis focuses on the development and production of epoxy, epoxy-hybrid and acrylic-based technology. The core range that Mavom offers consists of: electrically and thermally conductive adhesives, underfill products, glob tops, Dam & fill products and optically clear adhesives and coatings.
Higher capacities on smaller surfaces as a result of product miniaturization provide extra heat development. Thermally conductive products dissipate heat efficiently, leading to better reliability and longer life of electronic components.
An adhesive makes it possible to join dissimilar materials. Within Electronics, the applications are wide, such as: gluing SMA components, fixing large components, sealing a housing or gluing a PCB in a housing. The gluing process is also ideal for automation.
Electrically conductive adhesives are usually filled with metal particles, such as silver or graphite, and are used to electrically connect components together. Typical applications are the bonding of small components to temperature-sensitive substrates such as flex prints. Or as a replacement for solder pastes in applications where large thermal cycles are necessary.
On a printed circuit board, there can be naked chips on sensitive components that need to be individually protected. There are various techniques to protect such components against environmental influences and mechanically, namely Glob top and Dam & fill.
Underfill products are 1-component, epoxy-based products that fill the air bubble-free layer between BGA, CSP, flip chip and the printed circuit board and thus protect the active side of the component. At the same time, this layer reduces the thermal stress on the solder joints. This technique protects the components against shocks, vibrations and exposure to varying temperatures. Important properties for this type of product are a high glass transition temperature, low expansion coefficient and very good flow.
An important property for optical applications is that they do not yellow under the influence of UV and temperature. When it comes to semi-conductor applications, such as LED packages or optical lenses, it is also a requirement that the products have a high refractive index and a low ion content. In addition to optical products for the semiconductor industry, Mavom also offers die-attach, die-encapsulants and spin-on dielectric products.
