Ekwenziweni kwe-PCB evumelana nezimo, isici esibalulekile esingenakuzitshwa ukuhlanza nokunqanda ukungcoliswa. Lezi zinyathelo zihamba ibanga elide ekugcineni ukubukeka nokusebenza kwebhodi lesifunda.Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngokuthi ungazikhetha kanjani izindlela zokuhlanza ezifanele kakhulu nezokuvikela ukungcola zokukhiqiza i-PCB eguquguqukayo.
Ama-PCB aguquguqukayo asetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi i-aerospace, eyezimoto, yezokwelapha kanye neyabathengi.Lawa mabhodi aziwa ngokuguquguquka, ukukhanya, namandla okonga isikhala. Kodwa-ke, njenganoma iyiphi enye ingxenye ye-elekthronikhi, ama-PCB aguquguqukayo asengozini yokutheleleka futhi adinga ukuhlanzwa okuvamile ukuze kuqinisekiswe ukusebenza kahle.
Ukukhetha izindlela ezifanele zokuhlanza nezokunqanda ukungcoliswa zokwenziwa kwe-PCB eguquguqukayo kungaba umsebenzi oyinselele uma kubhekwa ubuthaka bala mabhodi. Inqubo kufanele ihlelwe ngokucophelela futhi yenziwe ukuvimbela noma yikuphi ukulimala kwesekethe. Nazi ezinye zezinto ezibalulekile okufanele uzicabangele lapho wenza lokhu kukhetha:
1. Ukuhambisana kwempahla: Kubalulekile ukukhetha izindlela zokuhlanza nezokuvimbela ukungcola ezihambisana nezinto ezisetshenziselwa ama-PCB aguquguqukayo.Izinto ezehlukene zivame ukusetshenziswa enqubweni yokukhiqiza, njengethusi, i-polyimide, nezinamatheliso. Qinisekisa ukuthi ama-ejenti okuhlanza nezindlela ezikhethiwe ngeke zidale noma yimuphi umonakalo noma ukucekelwa phansi kwalezi zinto.
2. Ukucatshangelwa kwemvelo: Imithetho yemvelo kanye nokucatshangelwa kufanele kucatshangelwe lapho kukhethwa izindlela zokuhlanza nokulwa nokungcoliswa.Khetha izixazululo ezivumelana nemvelo ezinomthelela omncane ku-ecosystem. Bheka imikhiqizo engenawo amakhemikhali ayingozi futhi uthobelane nemithetho efana ne-RoHS (Umkhawulo Wezinto Eziyingozi).
3. Izinto zokuhlanza: Kunezinhlobo eziningi zama-ejenti okuhlanza e-PCB avumelana nezimo emakethe. Ezinye izinketho ezivamile zihlanganisa abahlanza amanzi, izihlanzi ezisekelwe ku-solvent, nezixazululo ezikhethekile zokuhlanza.Isihlanzi ngasinye sinezinzuzo kanye nezingozi ezingaba khona. Hlaziya izidingo ezithile ze-PCB yakho eguquguqukayo bese ukhetha isicoci esifanele ngokufanele.
4. Ubuchwepheshe bokuhlanza: Ukuhlanza okuguquguqukayo kwe-PCB kungasebenzisa ubuchwepheshe obuhlukahlukene, njengokuhlanza ngesandla, ukuhlanza nge-ultrasonic, ukuhlanza isigaba segesi, njll.Ukukhethwa kobuchwepheshe bokuhlanza kuncike ezintweni ezifana nezinga lokungcola, ubunzima bebhodi lesifunda kanye nokuhlanzeka okudingekayo. Linganisa lezi zici bese ukhetha ubuchwepheshe obufaneleka kangcono izidingo zakho.
5. Ukuvikelwa kwe-ESD: I-Electrostatic discharge (ESD) ingalimaza izingxenye ezibucayi zama-PCB aguquguqukayo.Ngakho-ke, kubalulekile ukusebenzisa izindlela ezifanele zokuvikela i-ESD phakathi nenqubo yokuhlanza. Lokhu kungase kuhlanganise ukusebenzisa ama-anti-static, amabhande asesihlakaleni, nokuhlanza endaweni ephephile ye-ESD.
6. Ukuhlola Ngemva Kokuhlanza: Ngemva kokuba inqubo yokuhlanza isiqediwe, kubalulekile ukwenza ukuhlola okuphelele ukuze kuqinisekiswe ukuthi i-PCB ayinakho ukungcola nezinsalela.Lokhu kungenziwa kusetshenziswa izinto zokuhlola ezifana nezibonakhulu nezingilazi zokukhulisa. Noma yikuphi ukungcola okusele kufanele kubhekwane nakho ngokushesha ukuze kugwenywe izinkinga zokusebenza kwesikhathi esizayo noma ukwehluleka okungenzeka.
Ngokucubungula lezi zici ngokucophelela nokukhetha izindlela ezifanele zokuhlanza nezokuvimbela ukungcoliswa, ungakwazi ukulondoloza ukubukeka nokusebenza kwe-PCB yakho eguquguqukayo. Ukuhlanza njalo nokunakekela akugcini nje ukwandisa impilo yebhodi lesifunda sakho kodwa futhi kuqinisekisa ukusebenza okuthembekile nokungaguquguquki.
Ngokufigqiwe, ukukhetha okufanele ukuhlanza kanye nezinyathelo zokunqanda ukungcoliswa kokukhiqizwa kwe-PCB okuguquguqukayo kubalulekile ekugcineni ukubukeka nokusebenza kwebhodi. Cabangela izici ezifana nokuhambisana kwezinto, izici zemvelo, ama-ejenti okuhlanza, amasu okuhlanza, ukuvikelwa kwe-ESD nokuhlola ngemva kokuhlanza.Ngokwenza ukukhetha okuhlakaniphile, ungaqinisekisa ukuphila isikhathi eside nokuthembeka kwe-PCB yakho eguquguqukayo, ekugcineni unike amandla izinhlelo zokusebenza ze-elekthronikhi eziphumelelayo nezisebenza kahle.
