Te Hoahoa me te Huihuinga PCB Auau-Teitei: Ngā Rauemi Matua
Ngā papa ara iahiko tānga auau-teiteiHe wāhanga nui ngā PCB i roto i ngā momo tono, tae atu ki ngā whakawhitiwhiti kōrero, ngā pūnaha radar, te whakawhitiwhiti ahokore, me te tukatuka raraunga tere-teitei. He nui te awe o ngā rauemi i whiriwhiria mō tā rātou hoahoa me te huihuinga ki te mahi a ēnei PCB. E tūhuratia ana e tēnei tuhinga ngā rauemi matua e whakamahia ana i roto i te hoahoa me te huihuinga PCB auau-teitei, me te whakanui i ō rātou āhuatanga me ō rātou painga.
- Ngā Rauemi TūāpapaKo te rauemi turanga te turanga o tētahi PCB auau-tiketike, ā, he mahi nui tāna ki te whakatau i ōna āhuatanga hiko. Ko ētahi o ngā rauemi turanga matua e whakamahia ana i roto i ngā PCB auau-tiketike ko:
- FR-4He rauemi hiato karāhe epoxy ohanga, ā, e whakamahia whānuitia ana, e whakarato ana te FR-4 i te ātete pai ki ngā āhuatanga miihini me tepumau wera.Heoi, ko tōnapūmau whakawehenga hiko(Dk) metauwehenga memehaKāore pea te (Df) i te tino pai mō ngā tono auau teitei.
- Ngā Rauemi a RogersE mōhiotia ana a Rogers mō āna rauemi dielectric mahi-teitei, pērā i te RT/Duroid. He tino pai ngā uara o te pūmau dielectric (Dk) me te tauwehenga marara (Df), ā, he pai mō ngā tono PCB auau-teitei.
- Ngā Rauemi TaconicHe maha ngā rauemi hiko-whakakore mahi-teitei a Taconic, pērā i te PEEK (Polyether Ether Ketone) me te polyimide, e tuku ana i te pumau wera tino pai me ngā uara Df iti, e pai ai mō ngā ara iahiko auau-teitei.
- Ngā Rauemi AratakiHe mea nui te whiriwhiri i ngā rauemi kawe hiko i roto i te hoahoa PCB auau-tiketike, nā te mea ka whakatauhia e rātou te kawe hiko, te ātete, me te pono o te tohu o te ara iahiko. Ko ētahi o ngā rauemi kawe hiko e whakamahia whānuitia ana i roto i ngā PCB auau-tiketike ko:
- Parahi: Ko te parahi te rauemi kawe hiko e whakamahia whānuitia ana nā tōna kaha kawe hiko tino pai, ā,whai huatanga utuHeoi, ka piki ake tōna ātete i te auau, nō reira ka taea te whakamahi i ngā paparanga parahi angiangi i roto i ngā tono auau teitei.
- Koura: E mōhiotia ana te koura mō tōna kawe hiko tino pai me te iti o te ātete, ā, he pai mō ngā PCB auau-teitei. He pai hoki te whakaratoātete ki te waikurame te pakari. Heoi, he nui ake te utu o te koura i te parahi, ā, he iti noa iho tōna whakamahinga i roto i ngā tono e aro nui ana ki te utu.
- Konumohe: He iti ake te rongonui o te konumohe mō ngā PCB auau-teitei, engari ka taea te whakamahi i roto i ngā tono motuhake e aro nui ana ki te taumaha me te utu. He iti ake tōna kawe hiko i te parahi me te koura, ā, me whai whakaaro anō pea ki te hoahoa.
- Ngā Rauemi Hiko-koreHe mea nui ngā rauemi dielectric mō te ārai i ngā tohu kawe hiko i runga i te PCB, ā, he mea nui hoki ki te whakatau i ngā āhuatanga hiko o te PCB. Ko ētahi o ngā rauemi dielectric matua e whakamahia ana i roto i ngā PCB auau-teitei ko:
- Hau: Ko te hau te rauemi hiko-kore e tino kitea ana, ā, he tino pai te mahi hiko i ngā auau teitei. Heoi, he iti noa iho tōna pumau wera, ā, kāore pea e pai mō ngā tono pāmahana teitei.
- Pōrimide: Herauemi hiko-teitei rongonui mō tōna pumau wera tino pai me ngā uara Df iti. He maha te whakamahinga i roto i ngā PCB auau-teitei e hiahia ana kia tu atu ki ngā pāmahana teitei.
- Epoxy: He pai te pumau ā-pūkaha me te ā-wera o ngā rauemi dielectric e hangai ana ki te epoxy. He mea whakamahi noa ēnei i roto i ngā rauemi turanga FR-4, ā, he pai te mahi hiko tae atu ki tētahi auau.
He mea nui te whiriwhiri i ngā rauemi mō te hoahoa me te huihuinga PCB auau-teitei kia eke ki te mahi tino pai. He mea nui te rauemi turanga, ngā rauemi kawe hiko, me ngā rauemi dielectric katoa ki te whakatau i ngā āhuatanga hiko o te PCB, te pono o te tohu, me te pono. Me tino whiriwhiri ngā kaihoahoa i ēnei rauemi i runga i ngā whakaritenga tono motuhake kia pai ai te mahi me te mahi. I te haere tonu o te whanaketanga o te hangarau, ka puta tonu mai ngā rauemi hou me ngā whakapainga i roto i ngā rauemi o nāianei, ka whakanui ake i ngā kaha o ngā PCB auau-teitei.
