Isingeniso ku-PCB substrate

Ukuhlukaniswa kwama-substrates

Izinto ezijwayelekile eziphrintiwe ze-substrate zebhodi zingahlukaniswa zibe izigaba ezimbili: izinto eziqinile ze-substrate nezinto eziguquguqukayo ze-substrate.Uhlobo olubalulekile lwezinto ezijwayelekile eziqinile ze-substrate yi-copper clad laminate.Yenziwe nge-Reinforeing Material, efakwe nge-resin binder, yomisiwe, inqunywe futhi ifakwe emgqeni ongenalutho, bese ihlanganiswa nge-foil yethusi, isebenzisa ishidi lensimbi njengesikhunta, futhi icutshungulwe ngokushisa okuphezulu nokucindezela okuphezulu emshinini oshisayo.Ishidi elijwayelekile le-multilayer semi-cured, ligqokiswe ithusi kunqubo yokukhiqiza imikhiqizo eqediwe (ikakhulukazi indwangu yengilazi efakwe ku-resin, ngokusebenzisa ukucubungula).

Kunezindlela ezihlukahlukene zokuhlukanisa i-copper clad laminate.Ngokuvamile, ngokwezinto ezihlukahlukene zokuqinisa ebhodini, zingahlukaniswa ngezigaba ezinhlanu: isisekelo sephepha, isisekelo sendwangu yengilazi ye-fiber, isisekelo esiyinhlanganisela (uchungechunge lwe-CEM), isisekelo sebhodi le-multilayer laminated kanye nesisekelo sezinto ezikhethekile (i-ceramics, isisekelo sensimbi, njll.).Uma ibhodi esetshenziswa ezahlukene resin Adhesive for ngezigaba, iphepha ezivamile - CCI esekelwe.Kukhona: i-phenolic resin (XPc, XxxPC, FR 1, FR 2, njll.), i-epoxy resin (FE 3), i-polyester resin nezinye izinhlobo.I-CCL evamile i-epoxy resin (FR-4, FR-5), okuwuhlobo olusetshenziswa kakhulu lwendwangu yengilazi ye-fiber.Ngaphezu kwalokho, kunezinye izinhlaka ezikhethekile (indwangu ye-fiber yengilazi, i-polyamide fiber, indwangu engalukiwe, njll., njengezinto ezengeziwe): i-bismaleimide modified trizine resin (BT), i-polyimide resin (PI), i-diphenyl ether resin (PPO), maleic anhydride imide — styrene resin (MS), polycyanate ester resin, polyolefin resin, njll.

Ngokokusebenza kwe-CCL kwe-flame retardant, ingahlukaniswa ngohlobo lwe-flame retardant (UL94-VO, UL94-V1) nohlobo olungabusheki amalangabi (Ul94-HB).Eminyakeni eyi-12 eyedlule, njengoba kugxilwe kakhulu ekuvikelweni kwemvelo, uhlobo olusha lwe-CCL evimbela amalangabi ngaphandle kwe-bromine luye lwahlukaniswa, olungabizwa ngokuthi "i-CCL eluhlaza okotshani be-flame-retardant".Ngokuthuthuka okusheshayo kobuchwepheshe bomkhiqizo we-elekthronikhi, i-cCL inezidingo zokusebenza eziphezulu.Ngakho-ke, kusukela kusigaba sokusebenza se-CCL, futhi ihlukaniswe ngokusebenza okujwayelekile kwe-CCL, i-CCL ephansi ye-dielectric engaguquki, ukumelana nokushisa okuphezulu kwe-CCL(ipuleti elijwayelekile L ku-150 ℃ ngenhla), i-coefficient ephansi yokwandisa okushisayo kwe-CCL(ngokuvamile esetshenziswa ku-substrate yokupakisha) nezinye izinhlobo. .

Izinga lokusetshenziswa kwe-substrate

Ngokuthuthuka kanye nenqubekelaphambili eqhubekayo yobuchwepheshe be-elekthronikhi, izidingo ezintsha zihlale zibekwe phambili ezintweni eziphrintiwe zebhodi le-substrate, ukuze kuthuthukiswe ukuthuthukiswa okuqhubekayo kwamazinga epuleti le-copper clad.Njengamanje, izindinganiso eziyinhloko zezinto ze-substrate zimi kanje.
1) Amazinga Kazwelonke Wama-Substrates Njengamanje, Amazinga kazwelonke wama-substrates e-China ahlanganisa i-GB/T4721 — 4722 1992 kanye ne-GB 4723 — 4725 — 1992. Izinga le-copper clad laminates esifundeni sase-Taiwan e-China yizinga le-CNS, elisekelwe ngezinga lama-JIs aseJapan futhi lakhishwa ngo-1983.

Ngokuthuthuka kanye nenqubekelaphambili eqhubekayo yobuchwepheshe be-elekthronikhi, izidingo ezintsha zihlale zibekwe phambili ezintweni eziphrintiwe zebhodi le-substrate, ukuze kuthuthukiswe ukuthuthukiswa okuqhubekayo kwamazinga epuleti le-copper clad.Njengamanje, izindinganiso eziyinhloko zezinto ze-substrate zimi kanje.
1) Amazinga Kazwelonke Wama-Substrates Njengamanje, izindinganiso kazwelonke zaseShayina zama-substrates ahlanganisa i-GB/T4721 — 4722 1992 kanye ne-GB 4723 — 4725 — 1992. Izinga le-copper clad laminates esifundeni sase-Taiwan e-China yizinga le-CNS, elisekelwe ku I-Japan JIs ejwayelekile futhi yakhishwa ngo-1983.
2) Amanye amazinga kazwelonke ahlanganisa indinganiso ye-JIS yaseJapane, i-American ASTM, i-NEMA, i-MIL, i-IPc, i-ANSI ne-UL ejwayelekile, izinga le-British Bs, izinga le-German DIN kanye ne-VDE, izinga le-French NFC ne-UTE, izinga le-Canadian CSA, izinga le-Australian AS, izinga le-FOCT ye-Soviet Union yangaphambili, kanye nezinga le-IEC lamazwe ngamazwe

Izinga likazwelonke elijwayelekile lesifinyezo libizwa ngokuthi umnyango wokwakhiwa kwamagama ajwayelekile
