A wide variety of adhesives are used to manufacture complicated electrical and electromechanical devices. These adhesives are normally customized for the specific materials to be joined and are chosen to hold parts together indefinitely. Usually, no thought is given to disassembly.
However, disassembly is becoming an increasingly important aspect of manufacturing. For environmental and economic reasons, more manufacturers are concerned with "cradle to grave" management of their products. In addition, manufacturers are designing future electronic systems to be more assessable than in the past, so that expensive components can be repaired or upgraded.
One way to facilitate disassembly is with removable adhesive bonds. Easy disassembly of critical bonds allows products to be upgraded as new technology becomes available or rebuilt if defects are discovered during manufacturing or after deployment. Recycling is easier if bonds can be broken without damage to the components.
