He nui te whakamahinga o te parahi i roto i ngā hua ahumahi maha, ā, he rauemi maha ngā whakamahinga e kitea ai ēnei.
Ka hangaia ngā pepa konukōre parahi mā roto i ngā tukanga hanga motuhake i roto i te mira pepa konukōre tae atu ki te huri wera me te huri matao.
Haunga te konumohe, e whakamahia whānuitia ana te parahi i roto i ngā hua ahumahi hei rauemi tino maha ngā whakamahinga i waenga i ngā rauemi konganuku kore-ferrous. I ngā tau tata nei, kua piki haere te hiahia mō te pepa parahi mō ngā hua hiko tae atu ki ngā waea pūkoro, ngā kāmera mamati, me ngā taputapu hangarau mōhiohio.
Te hanga pepa konumohe
Ka hangaia ngā pepa parahi angiangi mā te whakanoho hiko, mā te hurihuri rānei. Mō te whakanoho hiko, me whakarewa te parahi kounga teitei ki roto i te waikawa hei whakaputa i te irahiko parahi. Ka panahia tēnei otinga irahiko ki roto i ngā pahu hurihuri kua rumakina ki roto, ā, kua utaina ki te hiko. Ka whakatakotoria he kiriata parahi angiangi ki runga i ēnei pahu. E mōhiotia ana hoki tēnei tukanga ko te whakakikorua.
I roto i te tukanga hanga parahi kua whakanohoia ki te hiko, ka whakatakotoria te pepa parahi ki runga i te pahu hurihuri titanium mai i te otinga parahi ka honoa ki te pūtake hiko DC. Ka piri te katote ki te pahu, ā, ka rumakina te anode ki roto i te otinga electrolyte parahi. Ina whakamahia he papa hiko, ka whakatakotoria te parahi ki runga i te pahu i a ia e hurihuri ana i te tere puhoi rawa. He maeneene te mata parahi i te taha pahu, ko te taha ke he taratara. Ko te puhoi o te tere o te pahu, ka matotoru ake te parahi, ā, ko te ritenga ke. Ka kukumea te parahi, ka kohia ki runga i te mata katote o te pahu titanium. Ka haere te taha matte me te taha pahu o te pepa parahi i roto i ngā huringa maimoatanga rerekē kia pai ai te parahi mo te hanga PCB. Ka whakarei ake ngā maimoatanga i te piri i waenga i te parahi me te paparanga dielectric i te wā o te tukanga whakakikorua parahi. Ko tētahi atu painga o ngā maimoatanga ko te mahi hei ātete-whakakino mā te whakaroa i te waikura o te parahi.
Pikitia 1:Te Tukanga Hanga Parahi Whakatakoto HikoKei te whakaatu te Pikitia 2 i ngā tukanga hanga o ngā hua parahi hurihuri. E toru ngā momo o ngā taputapu hurihuri; arā, ngā mira hurihuri wera, ngā mira hurihuri matao, me ngā mira pepa konutea.
Ka hangaia ngā porowhita angiangi o ngā pepa angiangi, ā, ka tukatukahia kia tae rā anō ki tō rātou āhua whakamutunga. Kei te Pikitia 2 tētahi tirohanga whānui o te tukanga hurihuri o ngā pepa parahi. Ka whakamahanahia he poraka parahi whakarewa (ngā rahinga tata: 5mx1mx130mm) ki te 750°C. Kātahi ka hurihia kia wera, kia hurihia hoki i roto i ētahi taahiraa ki raro ki te 1/10 o tōna matotoru taketake. I mua i te hurihuri makariri tuatahi, ka tangohia ngā unahi i ahu mai i te maimoatanga wera mā te mira. I roto i te tukanga hurihuri makariri, ka whakaitihia te matotoru ki te 4 mm pea, ā, ka hangaia ngā rau hei porowhita. Ka whakahaerehia te tukanga kia roa noa te rauemi, kia kore ai e rerekē tōna whānui. Nā te mea kāore e taea te hanga anō i ngā rau i tēnei āhua (kua whakapakeketia te rauemi), ka tukatukahia kia wera, ā, ka whakamahanahia ki te 550°C pea.
