already mounted components. There are also applications in pre-stage
processes, such as the AntiCorr® corrosion protection coating. By applying this coating to silver-plated or copper-plated LED lead frames, they are protected and corrosion is prevented. Before the introduction of this PlasmaPlus coating, LED manufacturers had to use nickel-gold, gold or nickel-gold- palladium coated lead frames. These surface coatings are no longer necessary due to plas- ma processing and can reduce both manufac- turing costs and production time.
More Applications Another application process
in the LED field is the prevention of epoxy bleeding. The bleeding of epoxy resins from the adhesives used is a phenomenon well-known in the industry. The bleeding sub- stance is often clear and colorless and surrounds the attach. The epoxy bleedout has a neg-
ative effect on the following steps in LED manufacturing, such as wirebonding. Typically, bleeding epoxy is removed in a vacuum plasma process. However, this process step can be avoided since barrier coating applied in advance using Openair-Plasma will pre- vent the bleeding. Even MSDs (moisture sensi-
tive devices) can be pretreated with Openair-Plasma to save costs for electronics manufactur- ers. Special handling or storage is no longer necessary, leading to cost reductions. With a Plasma - Plus coating in the production process, these components can be classified in a lower MSL (mois- ture sensitive level) classifica- tion. The ability for component manufacturers to bring their components to lower MSL offers great added value, as some elec- tronics manufacturers require that only components up to a cer- tain MSL can be used. Openair-Plasma has proven
its effectiveness in electronics manufacturing because the treat- ment of individual areas can replace processes such as surface cleaning with chemical cleaning media in a cost-efficient way. It offers almost unlimited possibili- ties for safe and reproducible
