He wāhanga nui ngā papa hiko tā. He maha ngā paparanga o ngā PCB o ēnei rā: te papa, ngā tohu, te kopare whakapiri, me te mata hiraka. Ko tētahi o ngā rauemi tino nui o te PCB ko te parahi, ā, he maha ngā take e whakamahia ai te parahi hei utu mō ētahi atu koranu pēnei i te konumohe, te tine rānei.
He aha ngā mea i hangaia ai ngā PCB?
E ai ki tētahi kamupene huihuinga PCB, he mea hanga ngā PCB i tētahi matū e kiia nei ko te papa, he mea hanga ki te muka karāhe kua whakakahangia ki te kapia epoxy. Kei runga ake i te papa he paparanga pepa parahi ka taea te hono ki ngā taha e rua, ki te taha kotahi rānei. Kia oti te hanga o te papa, ka whakatakotoria e ngā kaihanga ngā wāhanga ki runga. Ka whakamahia e rātou he kopare whakapiri me te mata hiraka me ngā ātete, ngā pūnga, ngā transistor, ngā diode, ngā maramara ara iahiko, me ētahi atu wāhanga tino motuhake.
He aha i whakamahia ai te pepa konutea parahi i roto i ngā PCB?
Ka whakamahia e ngā kaihanga PCB te parahi nā te mea he pai ake te kawe hiko me te wera. I te nekehanga o te iahiko me te PCB, ka ārai te parahi i te wera kei kino, kei whakararuraru rānei i te toenga o te PCB. Mēnā he koranu anō – pērā i te konumohe, i te tine rānei – ka kore e taurite te wera o te PCB, ā, kāore e mahi tika.
Ko te parahi te koranu pai rawa atu nā te mea ka taea e ia te tuku i ngā tohu hiko puta noa i te papa, me te kore e ngaro, e whakaroa rānei i te hiko. Mā te whai huatanga o te whakawhiti wera ka taea e ngā kaihanga te tāuta i ngā totohu wera tawhito ki runga i te mata. He whai hua te parahi tonu, nā te mea ka taea e te hekere parahi te kapi i te putu tapawha o te papa PCB he 1.4 mano o te inihi te matotoru, arā, 35 maikiromita.
He tino kawe hiko te parahi nā te mea he irahiko kore utu tōna ka taea te haere mai i tētahi ngota ki tētahi atu me te kore e whakaroa. Nā te mea he rite tonu tōna whai huatanga i taua taumata tino angiangi me tōna whai huatanga i ngā taumata matotoru, he nui te painga o te iti o te parahi.
Te Parahi me Ētahi Atu Konganuku Utu Nui e Whakamahia ana i roto i ngā PCB
E mōhio ana te nuinga o te tangata he kakariki ngā PCB. Engari, e toru ngā tae o te paparanga o waho: te koura, te hiriwa, me te whero. He parahi parakore anō hoki kei roto, kei waho hoki o te PCB. Ko ngā konganuku kē atu o te papa ara iahiko e kitea ana i roto i ngā tae rerekē. Ko te paparanga koura te mea tino utu nui, ko te paparanga hiriwa te tuarua o ngā mea tino utu nui, ā, ko te whero te mea tino iti te utu.
Te Whakamahi i te Immersion Gold i roto i ngā PCB
parahi i runga i te papa hiko tānga
Ko te paparanga koura e whakamahia ana mō ngā konganuku honohono me ngā papa wāhanga. Ko te paparanga koura rumaki kei reira hei ārai i te nekehanga o ngā ngota o te mata. Ehara i te mea he koura anake te tae o te paparanga, engari he koura tūturu. He tino angiangi te koura engari he nui hei whakaroa i te roa o te ora o ngā wāhanga e hiahia ana kia honohonoa. Mā te koura ka ārai i te waikura o ngā wāhanga honohono i te roanga o te wā.
Te Whakamahi i te Hiriwa Ruku i roto i ngā PCB
Ko te hiriwa tētahi atu konganuku e whakamahia ana i roto i te hanga PCB. He iti ake te utu i te rumaki koura. Ka taea te whakamahi i te rumaki hiriwa hei whakakapi mō te rumaki koura nā te mea ka āwhina hoki i te hononga, ā, ka whakaiti i te utu whānui o te papa. He maha ngā wā ka whakamahia te rumaki hiriwa i roto i ngā PCB e whakamahia ana i roto i ngā motuka me ngā taputapu rorohiko.
Papa Parahi i roto i ngā PCB
Engari mō te whakamahi i te rumaki, ka whakamahia te parahi i roto i te āhua kua whakakikoruatia. Koinei te paparanga whero o te PCB, ā, koinei te konganuku e whakamahia whānuitia ana. He parahi te konganuku turanga o te PCB, ā, he mea tika kia hono pai ai ngā ara iahiko, kia kōrero pai ai tetahi ki tetahi.
Me pēhea te whakamahi i te pepa konutea parahi i roto i ngā PCB?
He maha ngā whakamahinga o te parahi i roto i ngā PCB, mai i te papa parahi ki ngā tohu. He mea nui te parahi kia pai ai te mahi a ngā PCB.
He aha te PCB Trace?
Ko te ara PCB te āhua o tōna tangi, he ara hei whai mā te ara iahiko. Kei roto i te ara te whatunga parahi, te waea, me te whakamahana, tae atu ki ngā fiusi me ngā wāhanga e whakamahia ana i runga i te papa.
Ko te huarahi māmā ki te mārama ki tētahi ara ko te whakaaro he rori, he piriti rānei. Hei whakauru i ngā waka, me whānui te ara kia taea ai te pupuri i te iti rawa kia rua o aua ara. Me matotoru kia kore ai e hinga i raro i te pēhanga. Me hanga hoki i ngā rauemi ka tu atu ki te taumaha o ngā waka e haere ana i runga. Engari, he iti ake te mahi a ngā ara ki te neke hiko, kaua ki ngā motuka.
Ngā Wāhanga o te Ara PCB
He maha ngā wāhanga e hanga ana i te tohu PCB. He maha ngā mahi e tika ana kia mahia kia pai ai te mahi a te papa. Me whakamahi te parahi hei āwhina i ngā tohu ki te mahi i ā rātou mahi, ā, ki te kore te PCB, kāore he taputapu hiko. Whakaarohia he ao kāore he waea atamai, he pona, he mīhini kawhe, me ngā motuka. Koinei te mea ka whai tātou mēnā kāore ngā PCB e whakamahi i te parahi.
Matotoru o te Ara PCB
Ko te hoahoa o te PCB e whakawhirinaki ana ki te matotoru o te papa. Ka pā te matotoru ki te taurite, ā, ka hono tonu ngā wāhanga.
Whānui o te Ara PCB
He mea nui anō hoki te whānui o te tohu. Kāore tēnei e pā ki te taurite, ki te piri rānei o ngā wāhanga, engari ka pupuri i te rere o te iahiko me te kore e wera rawa, e kino rānei te papa.
Iahiko Whai PCB
He mea nui te iahiko PCB nā te mea koinei te mea e whakamahia ana e te papa hei neke i te hiko mā roto i ngā wāhanga me ngā waea. Ka āwhina te parahi i tēnei, ā, mā te irahiko kore utu i runga i ia ngota ka neke maeneene te iahiko i runga i te papa.
He aha i pania ai te pepa konutea ki ngā papahikohiko
Te Tukanga Hanga PCB
He rite tonu te tukanga hanga PCB. He tere ake te mahi a ētahi kamupene i ētahi atu, engari he rite tonu te tukanga me ngā rauemi e whakamahia ana e rātou katoa. Koinei ngā mahi:
Hangaia he turanga mai i te muka karāhe me ngā kapia
Whakatakotoria ngā paparanga parahi ki runga i te turanga
Tāutuhia, ka whakatakotoria hoki ngā tauira parahi
Horoia te papa i roto i te kaukau
Tāpirihia te kopare whakapiri hei tiaki i te PCB
Whakapirihia te mata hiraka ki runga i te PCB
Whakatakotoria, ka whakapiripiria ngā ātete, ngā ara iahiko whakauru, ngā pūnga hiko, me ētahi atu wāhanga.
Whakamātauria te PCB
Me whai wāhanga tino motuhake ngā PCB kia pai ai te mahi. Ko tētahi o ngā wāhanga tino nui o te PCB ko te parahi. E hiahiatia ana tēnei koranu hei kawe i te hiko ki ngā taputapu ka whakanohoia ngā PCB. Ki te kore he parahi, e kore ngā taputapu e mahi nā te mea kāore he koranu hei neke mā roto.
