I vakuumr\u00f8r-\u00e6raen blev fenolharpikslaminater typisk produceret med en tykkelse p\u00e5 1\/16 tomme (ca. 1,6 mm), og matchende stik og andre komponenter blev designet til denne specifikation og dannede gradvist en komplet industriel k\u00e6destandard.<\/p><p>Med den teknologiske udvikling er PCB-tykkelsen nu udvidet til 0,4-3,0 mm eller endnu bredere, men 1,6 mm er stadig standardvalget for de fleste elektroniske produkter p\u00e5 grund af dens gode mekaniske styrke, fremstillingskomfort og omkostningseffektivitet.Is\u00e6r for 4-lags printplader giver 1,6 mm tykkelse ideel isolering mellem lagene og strukturel stabilitet.<\/p><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Design_Considerations_for_4-Layer_16mm_PCB\"><\/span>Vigtige designovervejelser for 4-lags 1,6 mm PCB<span class=\"ez-toc-section-end\"><\/span><\/h2><h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Impedance_Control_and_Signal_Integrity\"><\/span>Impedansstyring og signalintegritet<span class=\"ez-toc-section-end\"><\/span><\/h3><p>I design af h\u00f8jhastighedskredsl\u00f8b er impedanskontrol afg\u00f8rende.Det 4-lags 1,6 mm PCB giver klare referenceplaner for signaler gennem dedikerede jord- og str\u00f8mlag, hvilket i h\u00f8j grad forenkler design af impedanstilpasning.
