Abstract:
1. A method of analyzing wire bonding operations for a specified capillary design of a wire bonding machine, comprising: performing multiple finite element analysis simulations modeling an actual wire bonding operation of the specified capillary design with a range of simulation inputs; developing first empirical equations relating to the inputs simulations based on simulation outputs from the multiple finite element analysis simulations; performing multiple actual wire bonding operations using the specified capillary design over ranges of actual wire bonding machine adjustment parameters; developing second empirical equations relating to the actual wire bonding machine adjustment parameters based on results of the multiple actual wire bonding operations; and combining the first and second empirical equations to provide correlated empirical equations for the simulation inputs as functions of at least some of the actual wire bonding machine adjustment parameters.
