Nowadays, compact and reliable electronic devices including up-to-date ceramic micro-electro-mechanical systems require thick-film resistors with significantly reduced dimensions and stable and precise resistance values. For that reason, instead of standard laser trimming method, high voltage pulse trimming of thick-film resistors is being introduced. This method allows controlled and reliable ...

An approach for thermal simulation and reliability evaluation of MCM film resistors is described. Result can be used to reach an optimal solution based on available data, technology, topology and material parameters. To achieve a high reliability level and performance of the resistors, the board must be designed taking into account the thermal consideration for each component. Result of thermal...
