Reparação de uma placa PLC
2 years ago
1
Neste vídeo faço a reparação de uma placa PLC, destinada ao controlo de uma plataforma elevatória de escada (e não de um elevador). Essencialmente, substituo dois circuitos integrados danificados, ambos do tipo ULN2803A, com outros integrados idênticos provenientes de outra placa. Adicionalmente, faço a emenda da pista danificada na placa de circuito impresso em reparação.
