Kunezindlela eziningi zokuhlukanisa ithusi eligqokiwe ithusi. Ngokuvamile ngokuya ngepuleti yokuqinisa impahla yehlukile, ingahlukaniswa: isisekelo sephepha, ingilazi yefayibha yendwangu,

Isisekelo esiyinhlanganisela (uchungechunge lwe-CEM), multilayer PCB isisekelo nesisekelo sezinto ezikhethekile (i-ceramic, isisekelo sensimbi yensimbi, njll.). Uma isetshenziswa yibhodi.

Izinto zokunamathisela i-resin zihlukaniswa ngokuhlukile, iphepha elijwayelekile elisuselwa ku-CCI. Kukhona: i-phenolic resin (XPc, XxxPC, FR-1, FR.

I-2, njll.), I-epoxy resin (FE 3), i-polyester resin nezinye izinhlobo. Ingilazi ejwayelekile yefayibha yesisekelo i-CCL ine-epoxy resin (FR-4, FR-5), njengamanje iwuhlobo olusetshenziswa kakhulu lwengilazi yefayibha. Ngaphezu kwalokho, kukhona ezinye izinhlaka ezikhethekile (ezinengilazi yefayibha yendwangu, i-polyamide fiber, indwangu engalukiwe njengezinto ezengeziwe): i-bismaleimide modified triazine resin (BT), i-polyimide resin (PI), i-diphenyl ether resin (PPO), i-maleic anhydride imide – I-styrene resin (MS), i-polycyanate ester resin, i-polyolefin resin, njll.

Ngokusho ilangabi cishe yizona ezisetshenziswa kabanzi ukusebenza CCL, ingahlukaniswa ibe ilangabi cishe yizona ezisetshenziswa kabanzi uhlobo (UL94 VO, UL94 V1 isigaba) futhi non-ilangabi cishe yizona ezisetshenziswa kabanzi uhlobo (UL94 HB ikilasi) izinhlobo ezimbili ipuleti. Emnyakeni owodwa kuya kwemibili yakamuva, ngokubhekelwa kakhulu ekuvikelweni kwemvelo, kwaqalwa uhlobo olusha lweCCL ngaphandle kwe-bromine kwi-flame retardant CCL, engabizwa nge- “green flame retardant CCL”. Ngokuthuthuka okusheshayo kobuchwepheshe bomkhiqizo we-elekthronikhi, i-cCL inezidingo zokusebenza eziphakeme. Ngakho-ke, kusukela kusigaba sokusebenza seCCL, ingahlukaniswa ibe yi-CCL ejwayelekile yokusebenza, i-CCL engaguquguquki ephansi ye-dielectric, ukumelana nokushisa okuphezulu i-CCL (ipuleti ejwayelekile L ngenhla kwe-150 ℃), i-coefficient yokwanda okushisayo ephansi ye-CCL (ejwayele ukusetshenziselwa ukufakelwa kwe-substrate) nokunye izinhlobo.

Ngokuthuthukiswa nokuqhubeka okuqhubekayo kobuchwepheshe be-elekthronikhi, izidingo ezintsha ze-PCB substrate materials zihlala zibekwa phambili, ngaleyo ndlela zikhuthaza ukuthuthukiswa okuqhubekayo kwamazinga ebhodi we-clad foil. Njengamanje, izindinganiso eziyinhloko zezinto ezisetshenziswayo zingokulandelayo.

② Izindinganiso ezisemqoka zamanye amazinga kazwelonke yilezi: I-JIS ejwayelekile yaseJapan, i-ASTM, i-NEMA, i-MIL, i-IPc, i-ANSI, i-UL ejwayelekile, i-Bs ejwayelekile yaseBrithani, i-DIN yaseJalimane, indinganiso ye-VDE, i-French NFC, i-UTE ejwayelekile, indinganiso ye-CSA yaseCanada, ejwayelekile yase-Australia AS, ejwayelekile yaseSoviet Union FOCT standard, Njengamanje, izindinganiso zikazwelonke zezinto ezisetshenziswayo e-China ziyi-GB / T4721-47221992 ne-GB4723-4725-1992. Ithusi egqoke ucwecwe ipuleti ejwayelekile endaweni yaseTaiwan eChina yi-CNS ejwayelekile, esekwe kumazinga ajwayelekile aseJapan futhi akhishwa ngo-1983.
