Deze wordt veel gebruikt in computers, communicatieapparatuur, industri\u00eble besturingen en consumentenelektronica, en biedt betrouwbare elektrische verbindingen en fysieke ondersteuning voor elektronische componenten.<\/p><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Characteristics_and_Advantages_of_Rigid_PCBs\"><\/span>1.

Hun belangrijkste kenmerken zijn:<\/p><ul class=\"wp-block-list\"><li><strong>Hoge mechanische sterkte<\/strong>: Het stijve substraat biedt een hoge weerstand tegen buigen en trillingen en is geschikt voor vaste installaties.<\/li>\n\n<li><strong>Uitstekende elektrische prestaties<\/strong>: Stabiele di\u00eblektrische constante en laag signaalverlies, geschikt voor hoogfrequente en hogesnelheidstoepassingen.<\/li>\n\n<li><strong>Goede thermische stabiliteit<\/strong>: Hittebestendig met een glasovergangstemperatuur (Tg) die doorgaans hoger is dan 140 \u00b0C.<\/li>\n\n<li><strong>Hoge bedradingsdichtheid<\/strong>Ondersteunt meerlaagse ontwerpen (meestal 4-12 lagen), waardoor complexe circuitlay-outs mogelijk zijn.<\/li><\/ul><p>In vergelijking met flexibele printplaten (Flex PCB's) zijn stijve printplaten goedkoper en hebben ze een meer volwassen productieproces, maar ze zijn minder flexibel en lichtgewicht.
