Reliable Surfaces for Robust Power Module Interconnection Technologies (AVT)
Understanding and optimizing surface interfaces – Maximize Yield, Minimize Failure Risks
Reliable Interconnection Technologies (AVT)Understanding and Optimizing Surface Interfaces
In the manufacturing of high-quality power modules, yield is a critical factor for overall cost efficiency. The multitude of material interfaces and boundary layers within these modules are exposed to significant thermomechanical stress—both during production and in the field.
At the same time, the mechanical integrity of these interfaces is key to the long-term reliability of advanced power modules.
This is particularly challenging when dealing with supplier components, as their surface characteristics are often difficult to specify and subject to process-related tolerances. These variations can reduce yield and negatively affect both quality and cost.
We support you with high-precision analytics to help you understand your surfaces—and, if necessary, with innovative wet-chemical surface modification to enable robust and reliable interconnections.
Reliable AVT ProcessesThese Assembly and Interconnection Processes Put Your Component Surfaces to the Test
The interfaces of components in power modules are subjected to significant thermomechanical stress—whether during manufacturing or in the field. This applies to processes such as wire bonding, terminal bonding, transfer molding, large area or baseplate sintering.
To ensure robust connections at these interfaces, wet-chemical surface modification can be a powerful enabler.
Wet-chemical surface modification means that your component surfaces are conditioned using specialized chemical treatments to achieve optimal properties for the respective process step. For example, specific surface characteristics can be adjusted to ensure ideal mold adhesion.
