Resumo
As placas de circuito impresso são a base de todos os equipamentos eletrônicos utilizados atualmente. Antigamente, as placas ocupavam grandes espaços e eram conectadas através de fios, válvulas e componentes eletromecânicos. Com o desenvolvimento dos circuitos integrados surgiram técnicas para a concepção de um circuito impresso no qual utilizam componentes cada vez menores e com alta velocidade de processamento. Porém, com a miniaturização dos componentes e redução das dimensões das placas de circuitos impressos surgem problemas de compatibilidade e interferência eletromagnética. Os estudos desses fenômenos demandam alto grau de esforços para os cálculos dos resultados. Diante dessa dificuldade são introduzidos softwares especialistas que utilizam algoritmos otimizados, obtendo melhores resultados em curto espaço de tempo. A fim de estudar os efeitos da compatibilidade e interferência eletromagnética usou-se uma placa de circuito impresso, de uma central telefônica. Através de simulações de integridade de sinal e compatibilidade eletromagnética pode-se fazer ajustes nas placas para atender às normas das agências reguladoras

Studies of these phenomena require a high degree of effort for the calculations results. Given this difficulty the introduced using specialist software algorithms optimized, permits obtaining better results. In order to study the effects of electromagnetic interference and compatibility it was used a printed circuit board in the development of a telephone exchange. Through simulations, signal integrity and electromagnetic compatibility can make adjustments on the boards in order that the board was able to be manufactured and sold meeting the standards of compatibility and electromagnetic interference
