I-flexible P-colored BB, eyaziwa ngokuthi I-Flex PCB, iqukethe ifilimu ye-polyimide evikelayo kanye nephethini yesekethe ephrintiwe. Ama-Polyimide angama-insulators, ngakho-ke indlela ingaqedwa kuphela uma iphethini yesifunda iqhuba. “Njenge-mask yokushisela” ye-PCB eqinile, i-PCB eguquguqukayo imbozwe “imbondela” encane evikela ukujikeleza kunoma yikuphi ukuphazamiseka kukazibuthe. I-Flex PCB manje isivamile kuma-smartphone nasezinhlelweni zezokwelapha, ikakhulukazi lapho amasekhethi engaphansi kwezinguquko eziqinile zokushisa kuyilapho ehlala eguquguquka.

I-PCBS eguquguqukayo ibhekwa njenge “eguquguqukayo” ngezizathu eziningi ezahlukahlukene. Okusobala kakhulu ukuthi ukujikeleza kwabo kungalungiswa ukuze kufane nomkhiqizo ngokwawo. Lokhu kunenzuzo ikakhulukazi uma kuziwa kumapharamitha njengokusimama, ukuqina, isisindo esiphansi kanye nokuvumelana nezimo. Amabhodi esekethe endabuko awakwazi ukuhlangabezana namazinga afanayo okuqina, ubuthakathaka nokusebenza kahle.

Amabhodi aguquguqukayo aphakeme kunamabhodi aqinile endabuko uma kuziwa emikhawulweni yomkhiqizo. Isibonelo, ukusebenzisa i-PCB eguquguqukayo esikhundleni se-hard drive kunganciphisa kakhulu usayizi womkhiqizo. Zingagotshwa futhi ziphetshwe ukuze zivumelane nomkhiqizo oyinhloko. Umkhiqizo wonke ungenziwa ube lula usebenzisa izingxenye ezifanayo njengezingxenye eziqinile nezisindayo. However, flexible plates are not completely flexible. La ma-PCBS anezindawo ezithile eziqinile, kepha ama-circry abekwe ikakhulu ezingxenyeni eziguqukayo, ngakho-ke zingalungiswa ngokuya ngomkhiqizo. Gcina izingxenye eziqinile ezisetshenziselwa ukusekela izinto ezibonakalayo ukuze zigcinwe ezingeni eliphansi kakhulu ngangokunokwenzeka.

1. Ukwakhiwa:

I-PCB eguquguqukayo engase ihambisane nokuqina kwayo ingase yakhiwe ngezindlela eziningi ezahlukene. Ngokuya ngobuchwepheshe, izinga nezinto ezibonakalayo, sizihlukanisa ngale ndlela elandelayo:

Isekethe eguquguqukayo yohlangothi olulodwa (SSFC) iqukethe isendlalelo esisodwa se-conductive esihlanganisa insimbi noma i-polymer egcwele insimbi kufilimu ye-dielectric eguquguqukayo; Ngokujwayelekile i-polyimide isebenzisa indlela ye-THT (ngembobo) ukukhweza ingxenye, okusho ukuthi ungasebenzisa uhlangothi olulodwa ukuze ulungise futhi uguqule ingxenye. I-PCB eguquguqukayo ehlangothini olulodwa enenamathela noma ngaphandle kwayo ingakhiqizwa kusetshenziswa ifilimu evikelayo; Kodwa-ke, ukusetshenziswa kwe-coating yokuvikela kusekethe kuwumkhuba ovame kakhulu ngoba kuvimbela umjikelezo nanoma iyiphi i-EMI. The structure and insulation of a single-layer flexible PCB are explained as follows:

I-PCB eguquguqukayo eqoshiwe iyisethi engaphansi ekhangayo ye-PCB eguquguqukayo, okusunguliwe kwamanje kuhlobene nendlela ethile yokukhiqiza eguquguqukayo ekhiqiza isekethe eguquguqukayo enama-conductor ethusi anogqinsi oluhlukahlukene ngobude bayo. I-conductor izacile endaweni eguquguqukayo futhi ishubile endaweni eqinile. This method involves selective etching of copper foil to obtain depth in various areas of the circuit.

Ukuqopha amasu e-PCB aguquguqukayo avame ukukhethwa ukuze kukhiqizwe othintana nabo bensimbi abangenalutho ukwenza lokhu kwenzeke. Inweba ukusuka onqenqemeni kuye ekuxhumekeni kwe-plug-in. Indawo eyandisiwe yenza amajoyinti e-solder azinze futhi ahlale eqinile kunezifunda ezijwayelekile eziguquguqukayo.

I-Multilayer flexible PCB iqukethe isekethe efanayo eguquguqukayo enezendlalelo eziningi. Lezi zingqimba zixhunywe ngamapuleti ayisicaba. Izendlalelo ze-PCB enezingqimba eziningi eziguquguqukayo zihlale zilamiwe ngezimbobo. Lawa ma-PCBS anezinhlaka eziningi afana ne-PCBS yezendlalelo eziningi eziqinile ngaphandle kokuhluka kokubalulekile, ikhwalithi, izici, kanye nezindleko. Amasekhethi anezingqimba eziningi aguquguqukayo abiza kakhulu kunozakwabo, kodwa aqinisekisa ikhwalithi engcono. Ngezansi ukubonakala kwe-PCB enezingqimba eziningi.

Ingxenye eqinile kuphela ingxenye esetshenziselwa ukujoyina. Lonke ibhodi lesifunda liguquguquka.

2. Isicelo:

I-Flexible PCBS isetshenziswa ezindaweni ezilandelayo:

Amabhodi wesekethe aphrintiwe aguquguqukayo avame ukusetshenziswa lapho kudingeka ukuthembeka, ukuzivumelanisa nezimo nemikhiqizo engasindi, njengakumadivayisi wezokwelapha. Iphilisi lokugwinya lekhamera elibizwa ngePill Cam lisebenzisa isekethe elincane kakhulu eliguqukayo okufanele lifakwe umbandela kahle futhi lihlale isikhathi eside. Ngemva kokugwinya iphilisi, odokotela nochwepheshe bangabuka ngokunembile izicubu ngaphakathi emzimbeni. Amaphilisi adinga ukuba mancane kakhulu futhi kufanele ahambe ngokuguquguquka emzimbeni, ngakho i-PCBS eguquguqukayo iyisinqumo esiphelele, ngokungafani nalawo aqinile futhi ama-brittle.

B) Amafoni ahlakaniphile:

Isidingo samafoni “ahlakaniphile” sidinga ukuthi amadivaysi eselula akhiwe izingxenye ezincane namasekhethi aguquguqukayo. Ngakho-ke, i-PCBS eguquguqukayo idlala indima ebalulekile kumasekhethi asetshenziswa kwezinye izingxenye ezibalulekile zesekethe, “njengama-amplifiers”. Ngakho amafoni angaba ahlakaniphile futhi angasindi.

C) I-Computer Electronics:

Imikhiqizo ye-elekthronikhi ebhodini lomama iwumongo nomoya wekhompyutha yesimanje. Idizayini yesiyingi kufanele isetshenziswe ngendlela encane, emfushane. Ngakho-ke, kusetshenziswa amabhodi wesifunda aguquguqukayo ukugcina konke kusimeme futhi kuncane.
