Prepreg PCB (Pre-impregnated PCB) ke karolo ea bohlokoa ho li-PCB tse ngata, tse sebelisoang haholo lihlahisoa tsa sejoale-joale tsa elektroniki ho pholletsa le liindasteri tse fapaneng. Ho Highleap Electronics, moetsi ea ka sehloohong oa PCB le setsebi sa kopano ea PCB, re utloisisa ka botebo bohlokoa ba lisebelisoa tsa Prepreg ho fihlela ts'epo le ts'ebetso e phahameng ea sehlahisoa. Sengoliloeng sena se hlalosa ka botlalo bohlokoa, thepa, mefuta, mekhoa ea khetho, ts'ebetso ea tlhahiso, le lits'ebetso tsa Prepreg PCB.

PCbiner pcb?

Prepreg PCB e bolela lesela la fiberglass le kentsweng pele ka resin epoxy e phekotsweng hanyane kapa ditsamaiso tse ding tsa resin ya thermosetting. Polelwana "prepreg" e emetse pre-impregnation, ho bolelang hore lesela la khalase le se le ntse le tletse resin, empa le dula le le boemong ba ho phekolwa hanyane. Boemo bona ba ho phekolwa hanyane bo nolofalletsa thepa ho phalla, ho kopana, le ho thatafala ka botlalo nakong ya tshebetso ya PCB lamination tlasa mocheso le kgatello e laolwang. Disebediswa tsa Prepreg di sebetsa e le lera la ho kopanya le ho thibela ho ruruha pakeng tsa difoile tsa koporo kapa di-core, tse bohlokwa bakeng sa meaho ya PCB ya mekhahlelo e mengata.

Sebopeho le Thepa ea Prepreg Material

Prepreg (lisebelisoa tse kopantsoeng pele ho kenyeletsoa) ke lisebelisoa tse mahareng tsa laminated tse sebelisoang haholo ho etsa multilayer PCB. E na le lesela le lohiloeng la fiberglass le kenngoeng ka sistimi ea thermosetting resin e phekotsoeng hanyane - eo hangata e thehiloeng ho epoxy - e kopantsoeng le palo e nepahetseng ea lisebelisoa le li-additives. Ts'ebetso ea prepreg maemong a lamination le a-in-service e itšetlehile ka sebopeho sa eona sa lintho tse bonahalang le boitšoaro ba eona ba ho sebetsa.

1. Fiberglass Reinforcement (Structural Backbone)

Lesela la fiberglass le fana ka thepa ea mantlha ea mochini oa prepreg:

• Setaele sa Weave (mohlala, 106, 1080, 2116, 7628) se etsa qeto ea ho ts'oaroa ha resin, dielectric constant, le dimensional botsitso.
• Litaba tsa khalase li ama matla a tsitsipano, katoloso ea z-axis, le ho satalla.
• Botenya bo ts'oanang bo netefatsa sebaka se tsitsitseng sa dielectric, se bohlokoa bakeng sa taolo ea impedance tseleng ea mats'oao a lebelo le holimo.

2. Resin Matrix (Ts'ebetso ea Dielectric le Adhesive)

Sistimi ea resin-hangata DICY- kapa phenol-cured epoxy-e ikarabella bakeng sa:

• Ho khomarela pakeng tsa li-foil tsa koporo le likarolo tse ka hare, ho nolofalletsang ho lamination ea multilayer.
• Tshebetso ea dielectric, e susumetsang Dk (dielectric constant) le Df (dissipation factor) ka maqhubu a itseng (mohlala, 1 GHz kapa 10 GHz).
• Thermal le lik'hemik'hale tse tsitsitseng, tse nang le lisebelisoa tse phahameng tsa Tg (> 170 ° C) tse sebelisoang lits'ebetsong tsa lebelo le holimo kapa tse tšepahalang tse kang RF, liboto tsa likoloi kapa tsa sefofane.

Lisebelisoa tse ling tsa prepreg li kenyelletsa li-resin tsa tahlehelo e tlase (mohlala, epoxy e fetotsoeng, polyimide, PTFE hybrids) ho ts'ehetsa ponts'o ea matšoao ho meralo ea microwave kapa millimeter-wave.

3. Li-Agents tsa Pheko le Li-additives tsa Phallo ea Phallo

Lisebelisoa tse phekolang tse kang DICY, anhydrides, kapa amine li kopantsoe le resin ho hlalosa:

• Pheko e sa lekanyetsoang (B-stage): e lumella prepreg hore e lule e le thata ebile e khonahala pele ho lamination ea ho qetela.
• Nako ea gel le boitšoaro ba ho phalla, bo tlamehang ho laoloa ka hloko ho netefatsa hore resin e koloba ka ho feletseng ntle le ho phunyeletsa ho feteletseng kapa sebopeho se se nang letho.
• Thempereichara ea phetoho ea khalase (Tg) le tekanyo ea khokahanyo ea sefapano, e laolang botsitso ba mocheso le mochini oa post-lamination.

Lintlha tsa bohlokoa tsa thepa ea Prepreg

Ho Khetha Boitsebiso bo Nepahetseng ba Prepreg: Lintlha tsa Bohlokoa

Ho khetha thepa e nepahetseng ea ho itokisetsa esale pele ke mohato oa bohlokoa moralo oa PCB oa mekhahlelo e mengata , o amang ka kotloloho ts'ebetso ea matšoao, botsitso ba mocheso, le mokhoa oa ho etsa. Sekahare sa resin le setaele sa ho loha khalase li khetholla botenya ba lamination le ho kenya mocheso lipakeng tsa mekhahlelo, tse bohlokoa bakeng sa ho boloka impedance e laoloang lipotolohong tsa lebelo le phahameng le tsa RF. Ho khetha botenya bo nepahetseng ho boetse ho thusa ho netefatsa hore ho tlamahana hantle le ho tšoana ha mekhahlelo nakong ea potoloho ea khatiso.

Ts'ebetso ea mocheso, haholo mocheso oa phetoho ea khalase (Tg), ke taba e 'ngoe e kholo. Bakeng sa liboto tse sebelisoang lits'ebetsong tsa likoloi, tsa indasteri, kapa tsa matla, Tg prepregs e phahameng (> 170 ° C) e fana ka khanyetso e phahameng ho delamination le ka mokhathala tlas'a libaesekele tse futhumetseng. Tekanyetso e phahameng ea Tg e boetse e netefatsa botsitso ba sekhahla nakong ea ts'ebetso ea phepelo e se nang lead le bophelo bo atolositsoeng ba ts'ebeletso libakeng tse thata.

Thepa ea dielectric, haholo-holo dielectric constant (Dk) le dissipation factor (Df), e ama botšepehi ba pontšo ka maqhubu a phahameng. Dk e tsitsitseng e bohlokoa bakeng sa taolo e nepahetseng ea impedance, athe Df e tlase e fokotsa tahlehelo ea mats'oao ho meralo ea lebelo le holimo. Bakeng sa RF, microwave, kapa litsamaiso tse thehiloeng ho SerDes, ho khetha lits'ebetso tsa prepreg tsa tahlehelo e tlase ho netefatsa phetisetso e tsitsitseng ea mats'oao ka ho bonahatsa ho fokolang kapa ho sotha.

Qetellong, litšobotsi tsa phallo ea resin li tlameha ho lumellana le litlhoko tsa sebopeho sa boto. Phallo ea resin e laoloang nakong ea lamination e thusa ho felisa likheo, ho tiisa hore ho khomarela lesela le thata, 'me ho tlatsa li-vias kapa likoti tse phuntsoeng ka katleho-haholo-holo ka HDI, ka-in-pad, kapa meralo ea boto ea cavity. Ho Highleap Electronics, lienjineri tsa rona li thusa bareki khethong ea prepreg, moralo oa li-stack-up, le mohlala oa impedance ho netefatsa ts'ebetso e nepahetseng, ts'ebetso le ts'epahalo.

Prepreg PCB Manufacturing Process and Industry Applications

Mokhoa oa Lamination ho Prepreg PCB Manufacturing

Tlhahisong ea Prepreg PCB, ts'ebetso ea lamination e bohlokoa ho theha meaho e tšepahalang ea boto ea multilayer. E kenyelletsa ho bokella likarolo tse fapaneng tsa li-laminate tsa koporo le maqephe a Prepreg, ebe o sebelisa mocheso o laoloang le khatello. Nakong ea ts'ebetso ena, resin ea B-stage ho prepreg e nolofatsa le ho phalla, ho tlatsa likheo le ho kopanya likarolo tsa koporo hammoho. Hang ha e se e phekotsoe ka botlalo, resin e ea tiea ho theha "Prepreg PCB" e matla, e tsitsitseng ka boholo.

Litaolo tsa Ts'ebetso e Bohlokoa bakeng sa li-PCB tsa Prepreg tsa boleng bo holimo

Ho netefatsa boleng bo tsitsitseng ho Prepreg PCBs, taolo e nepahetseng ea liparamente tsa lamination ke ea bohlokoa. Lintlafatso tse tloaelehileng tsa ts'ebetso li kenyelletsa:

• Vacuum lamination ho felisa ho kenella ha moea le likheo
• Mekhoa ea ho tlosa metsi pele u hatella ho fokotsa bokooa ba ka hare
