Temporary Bonding and Debonding in Advanced Packaging
An adhesive system consisting of hard adherends and a soft adhesive layer, such as a pressure-sensitive adhesive (PSA), can be called a "soft interface" adhesive system, as shown in Fig. 1b.According to Dahlquist''s empirical criterion [], the storage modulus of the soft adhesives does not exceed 0.1 MPa at 1 Hz and their …
These changes may be reversible, enabling the adhesive to rebond substrates after initial exposure to light. 88–91 Alternatively, UV-sensitive irreversible temporary adhesives can promote permanent debonding by increasing the polymer side-chain cross-linking density, creating interpenetrating networks, or by employing photodegradable linkers ...
Düsseldorf, Germany – As automotive electrification continues to evolve, powerful lithium-ion (li-ion) battery architectures are at the center of discussions around electric vehicles. While battery system designs vary by manufacturer, the joint performance objectives for all automotive batterytechnologies are longer lifetime, operational safety,...
Despite the load being evenly distributed in an adhesive-bonded connections, the stress distribution in the interface is nonuniform, which causes one of the main failure modes for an adhesive-bonded interface: the debonding of the two laps, which is very problematic to predict in practice . Therefore, frequent and thorough inspections …
