He nui ake te utu o ngā PCB uku i ngā papa FR-4 tuku iho?
Ae, he nui ake te utu o ngā PCB uku i ngā papa FR-4 tuku iho nā te mea he rauemi PCB hou, he pai ake hoki te mahi a te papa uku.
Me pēhea te hanga o ngā PCB uku?
Anei tētahi tukanga hanga māmā ake mō ngā PCB uku.
Whakaritea te rauemi mata → te paparanga o roto o te whakairo parahi → te whakahāngai → te keri → te paparanga o waho o te parahi → te tānga kopare whakapiri → te maimoatanga mata → te tānga mata hiraka → te whakamātautau tuwhera/poto → te tirotiro kounga whakamutunga → te takai.
Ka hangaia e Richfulljoy he PCB uku paparanga maha?
Ae, he nui ō mātou wheako ki te hanga PCB paparanga maha uku. Tena koa whakapā mai ki tā mātou tīma hokohoko kia whiwhi ai koe i tētahi whakatau utu kore utu mō tō hanga PCB uku.
He aha ngā rerekētanga matua: PCB uku me FR4?
1. He rerekē ngā papa;
2. He rerekē ngā whakamahinga;
3. He rerekē ngā utu: he nui ake te utu o te papa uku whakakikoruatia ki te parahi;
4, He rerekē te hanga: he uaua ake te tukanga hanga PCB uku.
He mea motuhake anō hei whakaaroaro māu i te wā e hoahoa ana i tētahi PCB uku?
I te wā e hoahoa ana i ngā PCB uku, kaua e whakahawea ki te hoahoa, ā, me mahara ki ētahi whakaaro.
I te hoahoa i tētahi PCB uku, me āta whiriwhiri tātou i te rauemi dielectric mō te tono e hiahiatia ana.
E hiahiatia ana te aukati whakahaere i roto i ngā PCB uku, nō reira me tatau e ngā kaihoahoa te uara aukati i runga i ngā tawhā rauemi (Er), te matotoru parahi, te whānui/wāhi parahi, te matotoru dielectric, me ētahi atu.
I te mea he nui ake te utu o te rauemi uku i te rauemi FR4, me whai whakaaro te hoahoa o te papa ara iahiko uku ki te utu PCB me te utu whānui mō te tono.
Ki te kitea wawetia ngā raruraru pea i roto i te tukanga hoahoa, ka taea e tātou te whakarite kia angitu i ngā wāhanga o muri mai. Mā te whakamahere tupato, ka taea e ngā PCB uku te whakarato i ngā otinga tino pai mō ngā tono maha. Tena koa whakapā mai ki a mātou mēnā he pātai āu e pā ana ki ngā PCB uku.
Kia pēhea te roa o te wā e hiahiatia ana mō te hanga PCB uku?
Ko te roanga o te wā e tika ana mō te hanga PCB he tata ki te 1-3 wiki. Engari i ētahi wā, ka hiahiatia pea he wiki torutoru hei hoko rauemi uku motuhake. Nō reira, ko ngā āhuatanga pēnei i te momo rauemi me te hangarau e whakamahia ana i runga i te PCB ka whakatau i te roanga tika mō te hanga PCB uku.
He aha te utu mō te PCB uku?
Ko ngā āhuatanga e whai ake nei e whakatau ana i te utu o te PCB uku.
Rauemi papa (te wāhanga tino nui);
Te rahinga mō ia puranga;
Hangarau Tukanga, pērā i ngā vias matapo/tāpuke;
Te uauatanga o te hanga, pērā i te manawanui ātete tino kikī, te manawanui whānui parahi kikī;
Ētahi atu whakaritenga motuhake.
He aha te rerekētanga i waenga i te PCB uku me te PCB Teflon?
He rerekē ngā rauemi:
He momo rauemi polyimide te Teflon, he momo kirihou mahi-teitei motuhake. Engari ko te uku he momo matū i hangaia mai i te boron nitride, te beryllium oxide me te silicon carbide.
He rerekē ngā whakamahinga:
E whakamahia ana ngā PCB Teflon mō ngā mahi ngaruiti me te RF. Engari ko ngā rauemi uku ka whakapakaritia ki te huinga o ētahi atu rauemi, nō reira he whānui ake te whakamahinga o ngā papa uku.
He rerekē ngā tukanga me ngā tikanga whakaputa PCB:
Nā te mea he tino rerekē ngā āhuatanga o ngā momo rauemi e rua.
