The defined absorption procedure for the "HTV – Long-Term Conservation" prevents the development and progression of oxidation/corrosion processes in a reliable and sustainable way.
Moisture and hazardous substances
Oxidation processes motivated through moisture and hazardous substances can cause, for example, the disintegration of conducting paths and isolation layers on long-term. The absorption process defined for the TAB®- procedure prevents reliably and sustainably from formation and progression of oxidation processes and corrosion processes. Additionally, hazardous substances, generated material-dependently, are absorbed.
Oxygen, resulting from the water molecule H2O, is the crucial factor for corrosion and oxidation. An oxygen atom with a low bond energy inside this molecule implements a high oxidation rate already at room temperature. Thus the direct cause for an oxidation is not the oxygen itself but it’s primarily the reaction with the moisture and hazardous substances of the surrounding atmosphere.
During production of electronic components, both, at fixing of dies and manufacturing of mold masses, one or two component adhesives, consisting substantial of resin, are used. In turn, these resins contain ingredients respectively hazardous substances, volatilising by and by. Located in closed packing (e.g. Dry-Packs), the hazardous substances accelerate the behaviour with regards to oxidation and corrosion of the components. As a consequence thereof the necessity of an absorption procedure is resulting.
The defined absorption procedure for the "HTV – Long-Term Conservation" prevents the development and progression of oxidation/corrosion processes in a reliable and sustainable way. Over and above we face the advantage of material-dependent absorption of the arising hazardous substances.
