4. Identify other assembly functions

4.1 Assembly set with external material input

This joint or adhesive (glue or double-sided) is a good way of fulfilling these functions.

Here is a non-exhaustive list of examples of functions to be performed:

• guarantee the anti-corrosion function of your assembly: substrates can interact with each other and corrode over time;

• distribute stress evenly to prevent breakage of fragile substrates;

• avoid surface degradation or embrittlement of substrates: friction between substrates or point stresses...
