Emkhakheni ovela ngokushesha wobuchwepheshe bokunakekelwa kwezempilo, indima yamabhodi esekethe aphrintiwe (PCBs) iya ngokuya ibaluleke kakhulu. Phakathi kwezinhlobo ezahlukene zama-PCB, ama-PCB ezokwelapha aqinile-aguquguqukayo asephenduke izingxenye ezibalulekile ezinezinzuzo eziningi ezisiza ukuthuthukisa ukusebenza kahle, ukuphepha, nokuthembeka kwemishini yezokwelapha. Lesi sihloko sinikeza ukubheka okujulile kwezinzuzo, izinhlelo zokusebenza, ukucatshangelwa kwedizayini kanye nokuhambisana nokulawula okuhlobene nama-PCB ezokwelapha aguquguqukayo embonini yokunakekelwa kwezempilo.
1. Isingeniso
Amabhodi esekethe aphrintiwe (ama-PCB) ayizingxenye ezibalulekile emishinini yezokwelapha, ehlinzeka ngenkundla yokuhlanganisa nokuxhumana kwezingxenye ze-elekthronikhi. Ikakhulukazi, ama-PCB ezokwelapha aqinile nezimo ahlanganisa izinzuzo zama-PCB aqinile futhi aguquguqukayo, anikeze amathuba okuklama ayingqayizivele emishini yezokwelapha.
Emkhakheni wemishini yezokwelapha, ama-PCB adlala indima ebalulekile ekunikeni amandla ukusebenza kwamasistimu e-elekthronikhi ahlukahlukene, njengemishini yokuxilonga, okokusebenza kokuqapha isiguli, izisetshenziswa zezokwelapha ezifakelwayo, nemishini yokuthwebula yezokwelapha. Ukuhlanganiswa kwama-substrates e-PCB aqinile futhi aguquguqukayo emishinini yezokwelapha kuye kwaholela ekuthuthukisweni okuphawulekayo, ukuthuthukisa ukusebenza, ukwethembeka kanye nokusebenza kwalawa madivayisi.
2. Izinzuzo zei-PCB yezokwelapha eqinile eguquguqukayo
Idizayini eguquguqukayo neyonga isikhala
Ama-PCB ezokwelapha e-Rigid-flex ahlinzeka ngokuguquguquka kwedizayini okungenakuqhathaniswa ukuze kuzuzwe izici zefomu eziyinkimbinkimbi nezihlangene ezihambisana nokuma nosayizi wezidingo zemishini yezokwelapha. Ukuvumelana nezimo kwalo mklamo akusizi nje kuphela ukonga isikhala kodwa futhi kwakha amadivaysi ezokwelapha ahlakaniphile nasebenza kahle alungele iziguli nabasebenzi bezempilo.
Thuthukisa ukwethembeka nokuqina
Ukuhlanganiswa okungenamthungo kwama-substrates aqinile futhi aguquguqukayo ebhodini lesifunda eliphrintiwe lezokwelapha kukhulisa ukwethembeka nokuqina. Ukuqeda ukuxhumana okujwayelekile nezixhumi kunciphisa ingcuphe yokwehluleka kwemishini ngoba ukuxhumeka okudayisiwe kudala amaphuzu ambalwa okuhluleka. Lokhu kwethembeka okwenyukayo kubalulekile ekusetshenzisweni kwezokwelapha, lapho ukusebenza okungaguquki nokunembile kwemishini kubalulekile ekunakekelweni kwesiguli nokuphepha.
Thuthukisa ubuqotho besignali futhi unciphise ukuphazamiseka kwe-electromagnetic
Ama-PCB ezokwelapha e-Rigid-flex ahlinzeka ngobuqotho besignali obuphakeme ngenxa yokuthi i-substrate eguquguqukayo inciphisa ukungafani kwe-impedance nokulahlekelwa kwesignali. Ukwengeza, inani elincishisiwe lokuxhumanisa linciphisa ukuphazamiseka kukazibuthe, liqinisekisa ukunemba kwamasiginali kagesi ezinhlelweni ezibucayi zezokwelapha ezifana nemishini yokuxilonga kanye nemishini yokuqapha isiguli.
Ibiza kakhulu futhi inciphisa isikhathi sokuhlanganisa
Izinqubo zokukhiqiza ezenziwe lula zama-PCB ezokwelapha aqinile zingonga izindleko futhi zinciphise isikhathi sokuhlanganisa. Ngokuhlanganisa ama-PCB amaningi abe idizayini eguquguqukayo eqinile, abakhiqizi bangakwazi ukunciphisa izindleko zempahla nezokuhlanganisa ngenkathi benza kahle inqubo yokuhlanganisa, okuholela ekongeni kwezindleko ngaphandle kokubeka engcupheni ikhwalithi noma ukusebenza.
3. Ukusetshenziswa kwe-PCB yezokwelapha eqinile nezimo
I-PCB yezokwelapha eyi-Rigid-flex isetshenziswa kabanzi kumishini yezokwelapha ehlukahlukene, kufaka phakathi kodwa kungagcini nje:
Imishini yezokwelapha efakelwayo
Ama-PCB aguquguqukayo abalulekile ekwakhiweni nasekusebenzeni kwamadivayisi ezokwelapha afakelwayo njengama-pacemaker, ama-defibrillators, ama-neurostimulators, nezinhlelo zokulethwa kwezidakamizwa ezifakelwayo. Imvelo eguquguqukayo yalawa ma-PCB iwavumela ukuthi avumelane nama-contours womzimba womuntu, okuvumela ukuthuthukiswa kwamadivayisi angavaleli kancane futhi athembeke kakhulu afakelwayo.
imishini yezithombe zezokwelapha
Emishinini yokucabanga yezokwelapha efana nemishini ye-MRI, izikena ze-CT kanye nemishini ye-ultrasound, amabhodi wesifunda sezokwelapha aqinile-flex adlala indima ebalulekile ekuhlanganiseni izingxenye ze-elekthronikhi eziyinkimbinkimbi kuyilapho enikeza ukuguquguquka okudingekayo ukuze kuhlangatshezwane nezithiyo zemishini zala madivayisi. Lokhu kuhlanganiswa kwenza izinhlelo zokuthwebula izithombe zisebenze ngaphandle komthungo, okusiza ukuzuza imiphumela enembile yokuxilonga nokunakekelwa kwesiguli.
imishini yokuqapha isiguli
Ama-PCB ezokwelapha e-Rigid-flex asetshenziswa emishinini yokuqapha isiguli, okuhlanganisa izinto ezigqokwayo, iziqapha ze-EKG, ama-pulse oximeters, nezinhlelo eziqhubekayo zokuqapha ushukela. Ukuvumelana nezimo nokuthembeka kwalawa ma-PCB kubalulekile ekuthuthukisweni kwamadivayisi okuqapha anethezekile nanembile anganikeza ochwepheshe bezokunakekelwa kwempilo idatha yesikhathi sangempela ukusiza ukuthuthukisa ukunakekelwa nokwelashwa kwesiguli.
imishini yokuxilonga
Amathuluzi asetshenziselwa ukuxilongwa kwezokwelapha, njengabahlaziyi begazi, abalandelanayo be-DNA, namadivayisi okuhlola indawo yokunakekela, azuza ekuhlanganisweni kwama-PCB ezokwelapha aguquguqukayo njengoba enza kube lula ukuthuthukiswa kwemishini yokuxilonga ephathekayo, ethembekile, nenembile. Lawa ma-PCB asiza ukuhlanganiswa okungenamthungo kwezingxenye ze-elekthronikhi ezithuthukisiwe, okusiza ukuthuthukisa ukunemba nokusebenza kahle kwezinqubo zokuxilonga.
4. Izinto okufanele uziqaphele umaukuklama i-PCB yezokwelapha eqinile eguquguqukayo
Lapho uklama ama-PCB ezokwelapha aqinile ezicelo zokunakekelwa kwezempilo, izici ezimbalwa ezibalulekile okufanele zibhekwe:
Ukukhetha okubalulekile
Ukukhetha izinto ezibonakalayo ngokucophelela kubalulekile ukuze kuqinisekiswe ukwethembeka nokusebenza kwama-PCB ezokwelapha aguquguqukayo. Ukukhethwa kwama-substrates, izinto zokunamathisela, nezinto zokuqhuba kufanele kusekelwe ezintweni ezifana nokuguquguquka kwemishini, izakhiwo ezishisayo, i-biocompatibility, kanye nokumelana nezinqubo zokuvala inzalo, ikakhulukazi kumishini yezokwelapha ehloselwe ukufakwa.
Ukubekwa kwengxenye
Ukubekwa kwezingxenye ze-elekthronikhi kuma-PCB ezokwelapha e-rigid-flex kudlala indima ebalulekile ekusebenzeni, ekuthembekeni, nasekukhiqizeni idivayisi. Ukubekwa kwengxenye efanele kuhilela ukwakheka okwenza isignali iqine, inciphise izinkinga ezishisayo, futhi ivumelane nemikhawulo yokulungisa idivayisi yezokwelapha kuyilapho iqinisekisa ukuhlanganisa nokugcinwa kalula.
Inqubo yokukhiqiza nokuhlola
Inqubo yokukhiqiza nokuhlola yama-PCB ezokwelapha aqinile-aguquguqukayo idinga ubungcweti obukhethekile nezinto zokusebenza ukuze kuqinisekiswe ikhwalithi, ukwethembeka kanye nokuthotshelwa kokulawula komkhiqizo wokugcina. Ukuhlola okuphelele, okuhlanganisa ukuhlolwa kukagesi, ukuhamba ngebhayisikili elishisayo, nokuhlolwa kokwethembeka, kubalulekile ukuze kuqinisekiswe ukusebenza nokuphepha kwama-PCB ezokwelapha ngaphambi kokuwahlanganisa emishinini yezokwelapha.
5. Ukuthobela Umthetho kanye Namazinga Ekhwalithi
Lapho usungula futhi ukhiqiza ama-PCB ezokwelapha aqinile embonini yezokunakekelwa kwempilo, ukuhlangabezana nezidingo zokulawula kanye namazinga ekhwalithi kubalulekile. Ukuhambisana nezindinganiso ezibekwe yi-US Food and Drug Administration (FDA) kanye ne-International Organization for Standardization (ISO) kubalulekile ukuze kuqinisekiswe ukwethembeka nokuphepha kwama-PCB ezokwelapha. Ukuthobela la mazinga kusiza ukunciphisa izingozi ezihlobene nokusetshenziswa kwemishini yezokwelapha futhi kukhulisa ukuzethemba kochwepheshe bezokunakekelwa kwempilo, izikhungo ezilawulayo kanye neziguli ekusebenzeni nasekuphepheni kwama-PCB ezokwelapha.

6 Isiphetho
Izinzuzo zama-PCB ezokwelapha aqinile neziguquguqukayo zithuthukisa kakhulu ukusebenza kwemishini yezokwelapha futhi zisize ukunikeza izixazululo zokunakekelwa kwezempilo ezithuthukile. Lawa ma-PCB anika amandla imiklamo eguquguqukayo neyonga isikhala, ehambisana nokuthembeka okuthuthukisiwe, ubuqotho besignali kanye nokusebenza kahle kwezindleko, okuwenza abe amandla abalulekile wokuqamba izinto ezintsha embonini yezokunakekelwa kwempilo. Ukubheka phambili, ukuqhubeka kwentuthuko kanye nokuqanjwa okusha kwezobuchwepheshe bemishini yezokwelapha, okuqhutshwa ngokwengxenye ukuthuthukiswa kwama-PCB ezokwelapha aqinile, kulindeleke ukuthi kuthuthukiswe ukunakekelwa kwesiguli, imiphumela yokwelashwa kanye nokuthuthukiswa kwemishini yezokwelapha yesizukulwane esilandelayo. Njengoba ubuchwepheshe bezokunakekelwa kwempilo buqhubeka nokuthuthuka, indima yama-PCB ezokwelapha aqinile ngokungangabazeki izohlala iyingxenye ebalulekile yokushayela okusha kumishini yezokwelapha kanye nokuhlinzeka ngezinsizakalo zokunakekelwa kwezempilo ezisezingeni eliphezulu.
