\u00bfQu\u00e9 es un PCBA?<\/h2>\r\n\r\n\r\n\r\n

Por PCBA (Printed Circuit Board Assembly) se entiende el ensamblaje de componentes electr\u00f3nicos en una PCB (Printed Circuit Board) mediante tecnolog\u00eda de montaje en superficie (SMT) o tecnolog\u00eda de agujeros pasantes (DIP), formando un m\u00f3dulo funcional completo. Es el \u201ccerebro y sistema nervioso\u201d de los dispositivos electr\u00f3nicos, ya que permite que la corriente y las se\u00f1ales fluyan ordenadamente entre los componentes.<\/p>\r\n\r\n\r\n\r\n

  • Una placa de circuito impreso consta de un sustrato aislante y trazas de l\u00e1mina de cobre.<\/li>\r\n\r\n\r\n\r\n
  • La l\u00e1mina de cobre se graba para formar patrones de circuito espec\u00edficos.<\/li>\r\n\r\n\r\n\r\n
  • Estos trazos act\u00faan como \u201cautopistas electr\u00f3nicas\u201d, conectando componentes como resistencias, condensadores, transistores y chips para formar una red de circuitos completa.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
