WebThe results show that during aging, tin is de-pleted from the solder/base metal interface. The two-phase Sn-Bi microstructure coarsens during aging; the rate of coarsening can be slowed by adding 1.0 wt. % Cu to the solder. The aging also affects the shear strength of the solder joints, where aged joints show an increase in maximum shear stress ...

Derangements are arrangements of some number of objects into positions such that no object goes to its specified position. In the language of permutations, a derangement is a permutation \sigma σ of n n elements with no fixed point; that is, \sigma (i) \ne i σ(i) = i for all i \in \ {1,2,\ldots,n\} i ∈ {1,2,…,n}. constantly in trouble
