Numerical methods of thermomechanical design in electronic assembly

The increase in interest in numerical design is, among other things, the result of increasing pressure of the electronics industry due to increasing competitiveness and consumer expectations. The problem of pro-ecological design is also important.

The miniaturization and integration of integrated circuits as well as the increase in the amount of information processed also means that efforts are being made to produce handheld devices and devices with increased functionality and working at ever higher frequencies.

Methods and numerical design algorithms become one of the key engineering tools. Selected methods and algorithms of numerical design in electronic assembly were discussed and a certain methodology was proposed, the aim of which is to optimize the reliability of electronic assembly, taking into account aspects such as sensitivity analysis and tolerance design.
