2 Layer OSP F4B High Frequency PCB
Mabapi le F4B High Frequency PCB
Wangling F4B e ipapisitse le litlhoko tsa ts'ebetso ea motlakase ea li-circuits tsa microwave,
Ke mofuta o motle oa boto ea potoloho e hatisitsoeng ea microwave e nang le thepa e ntle ea motlakase le matla a phahameng a mochini.
Moralo oa F4B High Frequency PCB
Moqapi oa PCB ea maqhubu a phahameng, baqapi ba atisa ho ela hloko haholoanyane dielectric constant (DK) le tangent loss (DF) ea PCB ha ba khetha thepa, 'me ba ela hloko feela botenya ba foil ea koporo ha ba khetha foil ea koporo, e leng bonolo ho hlokomoloha tšusumetso ea mefuta e sa tšoaneng ea koporo foil roughness ka thepa ea motlakase ea lihlahisoa.
Tlhahlobo ea SEM ea micromorphology ea mefuta e fapaneng ea foil ea koporo le sebaka sa ho kopana sa dielectric e bonts'a hore ho thata ha mefuta e fapaneng ea foil ea koporo ho fapane haholo.Moqapi oa mohala oa microstrip, ho ba thata ha foil ea koporo le sebaka sa ho kopana sa dielectric ho tla ama ka ho toba tahlehelo ea ho kenngoa ha mohala oohle oa phetisetso.
Lisebelisoa tsa lisebelisoa tsa F4B PCB
Wangling F4B e entsoe ka thepa ea boleng bo holimo ho latela litlhoko tsa ts'ebetso ea motlakase ea li-circuits tsa microwave.E na le ts'ebetso e ntle ea motlakase le matla a phahameng a mochini.Ke boto e ntle haholo e hatisitsoeng ea potoloho ea microwave.Tloaelehileng 15N / cm kamehla mongobo mocheso le 260 ℃ ± 2 ℃ fusion tjheseletsa thepa ho boloka 20 metsotsoana e ntle foaming, ha ho stratification le peeling matla ≥12 N/cm.
