| 摘要 |
<p>The present invention refers to an electric and/or electronic device comprising at least one source of electric current (3) or at least one input (5) for the electrical connection to at least one source of electric current (3), and a printed circuit (130, 230, 330, 430, 530), characterised in that it does not have a transformer device positioned between the at least one source (3) and the at least one printed circuit (130, 230, 330, 430, 530), and the printed circuit is at least partially electrically insulated (130, 230, 330, 430, 530). The invention also refers to the electrical insulation of printed circuits, to their heat transmission rate and to their surface finishing.</p> |
