Joang PCB PCB substrates classified?
Substrate, joalo ka ha lebitso le bolela, ke ntho ea mantlha, ke thepa ea mantlha ea tlhahiso boto ea potoloho e hatisitsoeng, Karolo e akaretsang ea PCB e entsoe ka lehoakhoa, lisebelisoa tsa matlafatso, lisebelisoa tse tsamaisang, ho na le mefuta e mengata. Lehoakhoa ke atileng ka ho fetisisa epoxy lehoakhoa, phenolic lehoakhoa, thepa matlafatso ho akarelletsa le pampiri, lesela khalase, joalo-joalo, lintho tse bonahalang tse atisang ho sebelisoa conductive ke koporo foil, foil koporo e arotsoe ka elektrone ea elektrolytic foil le calendered koporo foil.
PCB substrate lintho tse bonahalang tlhophiso:
E le ‘ngoe, ho latela lisebelisoa tsa matlafatso:
1. Karolo ea pampiri (FR-1, FR-2, FR-3);
2. Epoxy khalase ea fiber lesela substrate (FR-4, FR-5);
