Fuzzy models are not
constrained to be linear, and do not require exact
mathematical equations to describe the process.
Second, exact knowledge of all sigtuficant variables that
Sect process peformance is not easily gathered.
Accurately quantifjing the wire and material
characteristics and machine tool conditions is difficult.
although these can significantly affect the outcome of the
wire bonding process. Fuzzy models are relatively robust
in the case of inexact knowledge of model variables
