He kupu whakataki ki te taputapu PCB

Te whakarōpūtanga o nga taputapu

Ka taea te wehea nga rauemi papaa papaa whanui ki nga waahanga e rua: nga rawa maataki maataki me nga taonga taapiri ngawari.Ko tetahi momo mea nui o te papanga papaa maariki he raima whakakakahu parahi.He mea hanga mai i te Reinforeing Material, he mea whakamaroke ki te here kapia, ka whakamarokehia, ka tapatapahia, ka whakakikoruatia ki te parai, katahi ka hipokina ki te pepa parahi, ma te whakamahi i te pepa rino hei pokepokea, ka tukatukahia e te pāmahana teitei me te pehanga teitei i roto i te perehi wera.Ko te pepa whaanui-a-whaa-whakaoranga, he parahi te kakahu i roto i te mahi hanga o nga hua ahua-oti (te nuinga o nga kakahu karaihe kua ruia ki te kapia, na roto i te whakamaroketanga o te whakamaroke).

He maha nga tikanga whakarōpū mo te laminate kakahu parahi.Ko te tikanga, kia rite ki nga rauemi whakakaha rereke o te poari, ka taea te wehea ki nga waahanga e rima: te turanga pepa, te turanga papanga muka karaihe, te turanga hiato (raupapa CEM), te turanga papaa paparanga maha me te turanga rauemi motuhake (te karamu, te turanga whakarewa, etc.).Mena ka whakamahia e te poari nga taapiri rereke rereke mo te whakarōpūtanga, ko te CCI e pa ana ki te pepa noa.He: phenolic resin (XPc, XxxPC, FR 1, FR 2, etc.), epoxy resin (FE 3), polyester resin me etahi atu momo.Ko te CCL noa ko te epoxy resin (FR-4, FR-5), koinei te momo papanga muka karaihe e tino whakamahia ana.I tua atu, i reira e te tahi atu kapia motuhake (kakae muka karaihe, muka polyamide, kakahu kore-whatu, me ētahi atu, rite rauemi tāpiri): bismaleimide whakarerekē trizine resin (BT), polyimide resin (PI), diphenyl ether resin (PPO), maleic anhydride imide - styrene resin (MS), polycyanate ester resin, polyolefin resin, etc.

E ai ki te mahi mura o te CCL, ka taea te wehewehea ki te momo mura (UL94-VO, UL94-V1) me te momo mura kore (Ul94-HB).I roto i nga tau 12 kua pahure ake nei, i te mea kua nui ake te aro ki te tiaki i te taiao, kua wehea he momo hou o te CCL mo te mura o te mura me te kore bromine, ka taea te kiia ko "CCL mura-kaakaariki".Na te whanaketanga tere o te hangarau hua hiko, cCL he whakaritenga mahi teitei ake.Na reira, mai i te whakarōpūtanga mahi CCL, ka wehea ki te mahi whanui CCL, te CCL dielectric iti, te aukati wera nui CCL (paepae whanui L i te 150 ℃ i runga ake), te whakarea whakareatanga whakareatanga waiariki CCL (i te nuinga o te waa e whakamahia ana i runga i te taputapu kapi) me etahi atu momo. .

 

Paerewa o te whakatinana i te tïpako

Na te whanaketanga me te ahu whakamua tonu o te hangarau hiko, kei te tukuna tonu nga whakaritenga hou mo nga rauemi papaa papa taapapa, hei whakatairanga i te whanaketanga tonu o nga paerewa pereti kakahu parahi.I tenei wa, ko nga paerewa matua mo nga taputapu taputapu e whai ake nei.
1) National Standards for Substrates I tenei wa, Ko nga paerewa a-motu mo nga taputapu i Haina ko GB / T4721 — 4722 1992 me GB 4723 — 4725 — 1992. Ko te paerewa mo nga raima whakakakahu parahi i te rohe o Taiwan o Haina ko te paerewa CNS, kei runga i runga i te paerewa JI Japanese a i tukuna i te tau 1983.
